Ballast - If you equip your building with fluorescent tubes, high-intensity gas discharge lamps or linear plug-and-play LED lighting, you depend on ballasts. But which one is right for your application? We clarify. When you use the optimal ballast, you create a cost-effective and energy-efficient lighting solution that also gives you enhanced control over the amount of light produced in your space. Find the ballasts you need for lights and lighting systems easily at eibabo® in the extensive online range. In addition to ballasts in a wide variety of designs (electronic, DALI, KL/LL, EVG and many more), you will also find Powertronic devices and Quicktronic devices, QT-FIT ballasts, warm start devices as well as ignition devices and stabilization devices.What is a ballast?In fluorescent lighting, the ballast controls the power supply to the lamps. It provides sufficient starting voltage to start the lamps. Without a ballast, a fluorescent lamp connected directly to the mains voltage would quickly and uncontrollably increase the power consumption. Within a second the lamp would overheat and burn out. When the lamp is started, the ballast provides a brief high-voltage phase to build up an arc between the two lamp electrodes and start the ionization of the gas. This makes the gas inside the lamp electrically conductive. Once the arc is established, the ballast reduces the voltage. From that moment on, it serves to regulate the electric current in order to guarantee a constant light output.Please noteFluorescent tubes and gas discharge lamps have a negative, differential resistance during operation. As a result, as the current increases, there is a voltage drop across the lamp. For this reason, never connect gas discharge lamps directly to a voltage source.In order to achieve the full rated light output and maximum service life of a fluorescent lamp, the output characteristics of a ballast must exactly match the electrical requirements of the lamps being operated. Ballasts are typically designed in such a way that they operate a certain number of a certain lamp type with the necessary voltage. These are therefore also your primary selection criteria for the purchase of a ballast. So in order to find a suitable ballast that is compatible with a specific lamp, you should know the lamp type, lamp quantity and mains voltage.Why do only certain lamps need a ballast?Classic incandescent lamps and halogen lamps do not require ballasts. This is because the current flows through a filament. This filament resists the current, causing it to heat up and glow. It takes a lot of heat to illuminate a room bright enough. Therefore, the majority of this energy is used to generate heat and not light. This makes conventional incandescent bulbs very inefficient. LED lights also typically do not require ballasts. Here, LED power supplies and LED drivers regulate the current and voltage. The operation of fluorescent lamps and gas discharge lamps is slightly different. These are filled with gases and emit photons when charged with electricity. photonsPhotons are basic subatomic particles or waves that carry the electromagnetic force. In short: they are light particles. So in these lamps there is no filament to resist or regulate the electricity. The ballast is required for this.What types of ballasts are there?There are many different types of ballasts. The choice depends on the conditions in which your lighting is working. We distinguish between magnetic (conventional) ballasts and electronic ballasts.Conventional ballasts are the older technology and used to be responsible for flickering on start-up and lamp buzzing. Conventional ballasts have not been used since 2005 due to their low energy efficiency and high power losses of up to 20%.Nowadays, most fluorescent tubes and gas discharge lamps are operated with electronic ballasts. Electronic ballasts can emit multiple electrical frequencies without changing the input voltage. This eliminates any flickering and humming. These ballasts are available with different starting technologies:Quick StartInstant startprogrammed start Instant start ballasts switch the light on the quickest. However, these are designed for longer switching cycles. Frequent turning on and off can shorten lamp life. The devices are called instant starters because they immediately send a high voltage through the lamp to start the cathodes. Typically, instant start ballasts use slightly less power per lamp than quick start ballasts. Instant start lamps work reliably down to 0 °C.Already knew?Ballasts are also called 'ballast' in international usage. This designation is derived from their properties. Just as ballast stabilizes a ship's hull, a ballast stabilizes the power supply to a lightbulb or lamp.The ballasts work more slowly for both programmed start and quick start. However, these do not have the deleterious effects of an instant start ballast when switched on and off more frequently. The ballasts measure the temperature of the tube cathodes and preheat them. This makes starting easier and the lamp switches on immediately as soon as the light switch is pressed. However, quick-start ballasts also have disadvantages:The devices are not very energy efficient.Lamps connected to quick start ballasts do not turn on reliably at very low temperatures. Programmed start ballasts are typically coupled with occupancy sensors or motion sensors and maximize the number of lamp start cycles while maintaining energy efficiency. If you have high-traffic spaces in your building that experience multiple on-off cycles throughout the day, a programmed start ballast may be the best alternative for your lighting. Ballasts with programmed start are reliable even at low temperatures.When should I replace my ballast?Although replacement is not common, after a few years changes in ballast performance can become noticeable. If your lamps seem to be fading, humming, flickering or changing colour, it may be time to change the ballast.Image: Ledvance PTi 150/220-240 ballastAre ballasts equipped with a DALI interface?If you want to implement digital light control as part of your building automation, you may use the DALI system.What is DALI?DALI is the abbreviation for Digital Addressable Lighting Interface. It represents a programmable, digital interface for lighting scenarios including electronic ballasts. DALI is a protocol for light control in building automation, but not a bus system.DALI is suitable both for light control in individual rooms and for lighting scenarios in networked building management. As a rule, the modern electronic ballasts from most manufacturers are equipped with DALI interfaces. These interfaces establish direct communication between a control device and the lamps to be controlled. The communication between the control unit and the up to 64 connected devices takes place via a bidirectional two-wire line, so that information is transmitted both from the control unit to the lamps and vice versa. Programming the system is easy and hassle-free. For example, integration into a higher-level KNX building management system is possible via gateways.We offer you a large selection of ballasts from all well-known manufacturers such as ABB Stotz, Arclite, Ceag Notlichtsysteme, Houben, LEDVANCE as well as Philips lamps, Schuch Licht, Waldmann and Watt24.  Catalogue content:In this eibabo® catalogue Light control > Ballast you will find items from the following product groups:Item overview:BallastControl gearControl unitControllersDischarge lampFluorescent lampFluorescent lampsHeadlight bulbLightingLuminaire control gearOperating devicesPower supplyfrom the following manufacturers:Manufacturer overview catalogue Ballast:ABBArcliteCeagHoubenLEDVANCEPhilips LichtScharnberger+Has.SchuchSignify LampenSitecoZumtobel
Cooling system switch cabinet - Recooling systems are powerful devices with liquid cooling and an innovative solution for cooling electrical and electronic components. They are intended in particular for use in industrial control cabinets, server cabinets and data centers. This results in quite high power losses in the form of heat, which arise in the smallest of spaces and must be dissipated as efficiently as possible. Because the energy density of water and other liquids is up to a thousand times higher than that of air, the use of liquid-based recooling systems is recommended here. But also in numerous other manufacturing and manufacturing processes, a lot of heat is generated, which means that the use of recooling systems is absolutely necessary to ensure constant and optimal production conditions. High-quality recooling systems for small and also for particularly large industrial needs are available in the eibabo shop. Thanks to our high-performance logistics, you can also get heavy, large equipment quickly and safely directly to your company or construction site.Catalogue content:In this eibabo® catalogue Cabinet enclosures > Recooling unit (switchgear cabinet) you will find items from the following product groups:Item overview:Air conditioningChillerChiller (control cabinet)ChillersControl cabinet air conditioningCooling device for control cabinetDry cooler (switch cabinet)Heat exchangerLarge cooling unitLarge cooling unit (switch cabinet)Liquid cooling unit (enclosure/cabinet)Liquid systemLiquid system (switch cabinet)Machine coolingMachine cooling (switch cabinet)Oil cooling systemOil cooling system (switch cabinet)Process coolingProcess cooling (control cabinet)RecoolerRecooling systemRecooling system (switch cabinet)Recooling unit (enclosure/cabinet)Recooling unit (switchgear cabinet)Water chillerfrom the following manufacturers:Manufacturer overview catalogue Cooling system switch cabinet:Rittal
Cable ties - Do you want to hold lines, cables or other everyday things together, lash them down, fix them, connect them to each other - temporarily or for life? Cable ties are often a quick and very inexpensive solution. The selection of inexpensive and stable cable ties at eibabo® is huge. Here you can find out something about the history, areas of application and the properties of individual materials.Cable ties can be used universally and have become indispensable in our daily lives. These are handy, inexpensive and above all very versatile. Cable ties are used in the office, at home, on the go, when camping, as well as in trade and industry. But where does this useful everyday helper actually come from?The history of the cable tieCable ties originated in the United States of America. A cable tie was first patented there in the 1950s and was originally intended for fastening telephone cables.Already knew?The cable tie was born on October 1, 1954. On this day, the American George M. Rapata filed the corresponding patent in his name. This makes him the inventor of the cable tie.The first models were still made of metal. The further development and the commercial establishment of this idea is attributed to a Mr. Maurus S. Logan from the company Thomas & Betts. With the beginning of the industrial processing of plastics, this electrical company was able to produce the 'Ty-Rap'. The idea for the 'Ty-Rap' came to Logan in 1956 while visiting a Boeing airplane factory. At that time, the electrical wiring of the aircraft was still very complicated. Miles of wires were laid on long sheets of plywood and tied in place with waxed braided nylon cord. In view of this enormously lengthy manual work, Logan was convinced that there had to be a simple, durable and above all faster alternative. Over the next few years, Logan experimented with different tools and materials. On June 24, 1958, the 'Ty-Rap' cable tie was patented and marketed. In the decades that followed, the cable tie established itself more and more as a general means of attachment and thus found its way into almost all areas of everyday life.Flexible usageThe principle of the cable tie as a self-locking loop is even used in surgery. In this way, doctors fix broken bones or tie off vessels.Today there is hardly a household without cable ties. Whether for bundling power cables, fixing plants or as creative handicraft material - the possible uses are almost unlimited.Are there reusable cable ties?Cable ties are very inexpensive. The excess end is usually cut off after installation. This is why cable ties are usually disposable. However, there are some models that are reused.What types of cable ties are there?Cable ties differ in appearance and material. This results in different characteristics in terms of possible uses and durability. Among others, the following cable ties are widely used:Disposable cable ties:This is the classic cable tie. One end is pushed through the ratchet on the other end. This connection cannot be loosened again. To release the binding, the cable tie must be cut. Instead of a ratchet, there are also other self-locking systems, for example a clamping ball on metal cable ties.Bead Cable Ties:The design resembles a pearl necklace. The beads are threaded through a hole/two holes at the other end of the cable tie and hook into a taper of the respective hole. This holding connection is not as secure as with other models. A bead cable tie can be used again and again for this. This type of cable tie also comes in other designs, such as a herringbone or ladder shape.Multiple Cable Ties:Reusable cable ties have either a locking release feature (push button, rocker release, clip style) or a removable ratchet.Cable ties with marking:These models have flags or solid areas for written or printed identificationDouble loop cable ties:Here the ratchet sits in the middle and both ends can be pulled through the middle to form a loop.What special shapes are there for cable ties?In addition to the different types, there are also some special forms that are optimized for specific areas of application. Some cable ties have an eyelet or a fastening hole on the ratchet and can be attached to the ground with a screw. Other variants are supplied with a dowel including an impact pin. This means that electrical cables can only be laid on wood, brick and concrete surfaces using cable ties. Screws are no longer used. Cable ties with clamp anchors work in a similar way. This anchor is pushed through a hole in a metal surface and latches at the back. To fix a cable tie on a smooth surface, special pads with a self-adhesive layer are available. These can (additionally) also be fastened with a screw.What are cable ties made of?Cable ties are made of different materials. Which material you should use depends on the place of use and the desired durability. Cable ties are most commonly made from flexible nylon. At least 2% carbon black is added to nylon to increase resistance to UV light in outdoor applications. This protects the polymer chains and extends the life of the cable tie. In the food industry, cable ties contain a metal additive so that they can be detected by industrial metal detectors. ETFE (ethylene tetrafluoroethylene copolymer) cable ties are used in radiation hazardous environments. Stainless steel cable ties are available for explosion proof applications. Coated stainless steel cable ties prevent corrosion between dissimilar metals.Image: Cable ties from various manufacturersWhat affects the durability of a cable tie?Nothing is forever. Cable ties are also subject to a certain amount of wear or age over time. Then the moment has come to replace a cable tie. The following circumstances affect the durability of the cable ties:Temperature: At temperatures above 85 degrees, nylon loses its elasticity and strength. When cold, it becomes brittle and breaks.Humidity: If the air humidity is permanently high, the cable ties absorb moisture and the strength decreases.Material thickness: A larger material cross-section increases the service life.Vibration: Microcracks form due to constant vibrations, which lead to the destruction of the product.Radiation: Sunbeams and other radiations also affect the strength of the plastic structure.Mechanical stress: Twisting, pulling or abrasion lead to premature closure of the materialChemicals: Decomposing substances of all kinds and their vapors reduce durability. What do I need a cable tie tensioner for?A cable tie tensioner can be used to apply a cable tie with some tension. The tool trims the excess end flush. This will avoid a sharp edge that could otherwise cause injury. If you want to process a large number of cable ties, the tensioner offers the following advantages:convenient and fast workprovides the necessary tensionthe force regulator guarantees a uniform attachmentgrab and pull with one handSave time by automatically cutting the end piece Do the material colors have a specific meaning?In addition to a large variety of materials, we offer you natural-colored and black cable ties as well as various other material colors. The bright colors in particular are used for easy visual recognition in dark environments. The use of a specific color for a corresponding application is not prescribed. TIP:Tie together matching cables with cable ties of the same color. This makes sorting, separation or recognition within cable harnesses or in other rooms easier. At eibabo® you will find cable ties according to your wishes. Choose from classic models or designs that have been specially developed for a specific application. Well-known manufacturers are 3M, ABB, Fischer, OBO, Lapp, Rittal, Hama, Phoenix, Schneider Electric and around a dozen others.  Catalogue content:In this eibabo® catalogue Fasteners > Cable tie you will find items from the following product groups:Item overview:Ball lock cable tieBinderBolt headBundeswehr cable tiesCable fixerCable retention strapsCable strapsCable tie spoolChristmas treeDouble head tieFastening clampFastening systemFlat profile beltIdentification binderLamella footLamella foot binderMetal clampMounting tieOpening cable tiePlasticPlastic cable tiesPlug-in cable tiesStainless steel binderStainless steel cable strapSteel nose cable tiesTape materialTriple tapeVelcro strapfrom the following manufacturers:Manufacturer overview catalogue Cable ties:3MABBCellpackCimcoDeviFischer DEHamaHellermann TytonLappLegrand BticinoLegrand CablofilOBOPanduitPhoenixRittalSchneider ElectricTehalitWeidmüller
Wall light - Discover the wide range of wall lamps in the eibabo luminaire catalog. Wall lamps offer excellent opportunities to bathe your rooms in dramatic lighting, while guaranteeing sufficient lighting. Wall lights are an elegant solution, if you want to create special effects with lighting and give your room a very pleasant flair. However, the installation of such lamps requires a bit more effort, since structural modifications for installation are often required. You can install several wall lights one behind the other (eg in a corridor) or in pairs. This way, you can highlight specific areas, such as pictures or mirrors on the walls. The installation of wall lights is often easier than the installation of recessed lights, because the lights can be fastened to the wall with screws. The wall lights in the eibabo range offer a wide variety of shapes and designs, as well as different materials with different color designs and surfaces. You can choose between classic, modern or timeless styles. Create special lighting effects in your house or apartment with a wall light from our lamp catalog.

Fan switch cabinet - What to do if too much heat is generated in the control cabinet? Install fans or install air conditioning? Is an additional filter necessary? Where are the differences? We clarify. Prevent excessive temperatures in the control cabinet and protect your sensitive technology from defects and a shortened service life.With the use of technical devices, heat is always generated. Under normal circumstances this is not a problem. However, the more technology is installed in your control cabinet, the more likely it is that the temperature will rise above a critical value. When heat builds up in that small space, it's time to take countermeasures. With the eibabo® control cabinet fans, you ensure a better climate and protect your sensitive electronics from damage caused by overheating. The fans of the individual fans are designed and dimensioned differently depending on the model. This means that you too will find the best solution for optimal convection in the control cabinet.Position devices correctly in the control cabinetIt would be best if you didn't need separate cooling or ventilation for your control cabinet. Additional cooling and ventilation of the cabinet body always poses several challenges.You need a device.The device must be assembled.A power supply must be established.Regular maintenance should also take place. However, improving the natural flow of air is often enough to solve some problems. The first and perhaps most important step is to correctly position the components in the control cabinet. Devices that emit a lot of heat should not be placed close together. The wiring must also be laid properly so that the air has the opportunity to circulate. In order to increase the natural flow of air, there should be ventilation openings with grilles and filters in the upper area of the control cabinet. As soon as a natural air flow is possible, the warm air circulates and rises more easily. In many cases, this already improves the control cabinet climate. If this is still not enough to noticeably reduce the temperature, installing a fan or fans can be very effective. You have already created the conditions for the best possible air circulation by optimizing the device positions.Does it really make sense to buy a fan for the control cabinet?Installing air handling units for switch cabinets may seem like another unnecessary expense. Compared to the value of the devices in the control cabinet, however, these costs can be neglected even for high-quality fans. However, if this is omitted or the wrong fan is selected, the entire control cabinet can overheat. This not only jeopardizes the value of the devices contained therein, but also the actual function of the system. This can be the power supply for an entire process flow in a factory or the provision of the computer network within a data center. The consequences of such a failure have far-reaching consequences. Therefore, the installation of a comparatively inexpensive ventilation system makes sense in any case. TIP:Overheating of expensive devices due to the lack of active ventilation is one of the main reasons for their failure. Effective ventilation extends the service life and significantly increases the energy efficiency of the devices. A simple solution for good ventilation of the control cabinet is a combination of ventilation device and filter unit. In complex systems, ventilation systems are already part of the standard equipment of a control cabinet and are an essential part of the system design. If you would also like to increase reliability, simply take a look around in this catalogue. You will find the right fans and filters for almost every requirement.How do I choose the right fan for my control cabinet?When choosing the right ventilation system, you should consider a few things. Ventilation is basically intended to cool the devices in the control cabinet, not to heat them. Yes, even cold and frost damage the technology. So if you have a problem with temperatures that are too low or condensate for certain reasons, air conditioning units or heaters for control cabinets are more suitable for you.In order to ensure optimal ventilation and a long service life for the devices installed in the cabinet, the dimension and capacity of the ventilation devices must be calculated and selected correctly. The calculations themselves can be done expensively using manufacturer software, or quite easily done manually. For this you need:the difference between the maximum ambient temperature outside the control cabinet and the maximum permissible temperature inside the control cabinetthe heat loss behavior of the devices installed in the control cabinet in watts On the Internet you will find tables and diagrams in which you can read off the required ventilation performance (air volume in m³) based on these two values. Please note that this is a simplified calculation. Other conditions not considered here are:the size of the closetthe size and position of the openings for supply air and exhaust airthe cabinet material, installation conditions or installation environment and its insulationthe atmospheric pressurethe type of installation of ventilation High quality fans should have ball bearings. Also note how easy it is to dismantle the filter material on the ventilation grille. The cover should be easily removable to access the filter media. With a classic ventilation system, the fan first sucks the air through the air slots and then through a filter into the housing. The warm air exits through another filter mesh, which should be at least the same size as the intake. If necessary, this can also be larger in order to improve the flow behavior. Control cabinet fans must provide adequate protection against dust and splash water in order not to reduce the degree of protection of the control cabinet. Therefore, when buying, pay attention to the relevant information from the manufacturer, the presence of seals and the shape of the slats.NoticeIf the required air exchange cannot be achieved by the built-in fans and filters, there is a wide range of additional axial fans and centrifugal fans to choose from. If required, you will also find powerful air conditioning units for control cabinets here in the shop.Axial fans are typically used as exhaust fans to extract heated air from the system. When equipment is tightly housed in an enclosure, even exhaust fans may not suffice. In such cases, centrifugal fans are often used to blow cold air into the enclosure from the surrounding space, usually from the bottom of the cabinet.How and where are control cabinet fans installed?Control cabinet fans are usually used in the lower area of the control cabinet. Depending on how the cabinet is fixed (wall mounting, built-in, free-standing), choose a suitable position in a side wall, at the back or in the door. Since warm air rises, the exhaust air grille with filter is also installed on the top of the control cabinet. If you decide to use a duct in the ceiling of the cabinet, please consider the risk of inflowing liquids.Image: Rittal SK 3240.124 TopTherm filter fanUnder what circumstances should I better choose an air conditioner?There are conditions in which a classic ventilation system is no longer sufficient. If, for example, the air temperature outside the cabinet is too high or the quality of the air is too bad, an enclosure air conditioning system can be an alternative. These are designed in such a way that excess heat from control cabinets and device housings is dissipated to the environment. Use a control cabinet air conditioning system if:the ambient air contains too much humiditythe temperature inside the housing must be equal to or lower than the ambient temperaturethe ambient air is very pollutedthe required heat dissipation cannot be provided by the environment To make it easier for you to choose from our large range, the products are already sorted by relevance as standard.

Single position switches - Do you want to use single-position switches to control movements? Then use single position switches or limit switches. But what types of single-position switches are there and where are they best used? Find out here. Their functional principle is the same as with conventional switches, except that the switching process is automated or determined by external influences. Such an installation will help you avoid manual shifting where it is particularly difficult and/or dangerous.Image: Schneider Electric XCKM115H29 position switchWhat are single position switches?You won't use single-position switches that often in your home. Their areas of application are more in the industrial sector. There they ensure that a hydraulic, pneumatic, electrical or mechanical signal is triggered when a moving object has reached a specific position within a sequence control. This means, for example, that the position switch is activated or deactivated when the end of a specific production section has been reached and the next step in the process is to be started. Single position switches are also called limit switches, position switches or limit switches.What types of single position switches are there?Since the requirements in the industrial sector often depend on the respective process, the individual position switches can also be very different. A suitable solution is available for almost every application. In the following we will go into more detail about the functional principles and properties of the individual variants.Mechanical single position switchesSingle position mechanical switches can be found in both production and household settings. These switches often take the form of a button, roller, float, or lever. The classic example of the use of a mechanical single-position switch is the elevator. Only when the elevator car has reached a certain position can the door be opened. But these devices are also used in living areas in the form of microswitches. These can be found on front doors, for example, so that the lighting is switched on automatically when they are opened.Single position switch with push button or wheel switchThese versions of the single position switches consist of a housing with electrical contacts that can either open or close. These are connected to a roller with a push button or a rod. The functional principle here is also a movement mechanism. For example, if the wheel collides with another object, it is pushed down by a rod. This opens or closes the contacts in the housing and triggers a follow-up action.AssemblyWhen installing such a single-position switch, particular attention must be paid to accuracy. Otherwise, the movement of an object may not actuate the roller or push button properly, or, conversely, apply too much pressure.This may then lead to faulty switching or damage to the mechanism.micro switchSingle position switches as micro switches are used in electronics as well as in household appliances and are very small. Thus, these devices have special properties. Due to the compact dimensions, the stroke of the working part is small. As a result, installation often requires fine tuning or the use of an intermediate link. This makes it possible to increase the stroke of the working part to the extent required to ensure reliable switching.Non-contact single position switchesThis type of single position switch is widely used in industrial production. The market offers numerous variants as well as different functional principles and designs. The most important are:reed switchThis type of limit switch reacts to a magnetic field. These devices consist of several pairs of ferromagnetic contacts. The contacts inside the reed switch close or open when a magnet approaches. Since no mechanical movements trigger the contact process, the service life of the switch increases significantly. A magnet must be present as a trigger during installation, as these devices do not react to other materials. The field of application of reed switches is very diverse. These often work as a microswitch variant, for example as an alarm switch on doors and gates. When the door is closed, the magnetic field acts on the reed switch and the circuit also remains closed. When the door is opened, the magnet moves away from the reed switch. The contact opens and the alarm is triggered.Inductive switchesInductive switches are suitable alternatives to mechanical types of position switches and work without direct contact. The devices work by means of an inductor, which reacts to metal. Compared to the reed switch, these switches do not require a magnet. Inductive models are used in security systems because they respond to both the weight of a metal and its movement. The advantage of inductive switches is their tolerance to environmental pollution. As a result, inductive switches are mainly used in technological processes of industrial production. The size can vary greatly depending on the place of use and function.Switches with optical sensorsSwitches with optical sensors are also non-contact single-position switches. Such devices are often used in areas where special accuracy is required. Optical position switches work according to several principles.Reflective sensors send and receive light, which is reflected by an object located in the sensor area. Receiver and transmitter are in the same housing. The captured light energy causes a specific action at the output of the switch. The distance from the object to the sensor depends on its dimensions, texture, color and so on. If the light beam is crossed by another object and thus changes the captured light energy, a control signal is emitted. The range of such a position switch depends on the environment and its transparency.With passage sensors, the receiver and light source are separate and face each other. An object entering the area of the light beam interrupts the light and thereby changes the light energy. Then a signal is triggered.Capacitive position switchesThe principle of operation of capacitive position switches is as follows: The active surface of the switch consists of two metal electrodes. These can be thought of as capacitor plates. If an AC voltage is applied to it, current flows. The strength of the current flow depends on the medium located between the plates, the distance between the plates and the plate size. TIPCapacitive switches detect conductive and non-conductive materials in liquid, powder, or solid states. When an object appears near the active surface, the strength of the current flow changes. The position switch reacts to this and triggers an action.Are there also wireless single-position switches?Wireless instead of cable ? the wireless position switch offers you additional flexibility when designing machines and systems. You can mount these switches on fixed and moving components without a great deal of assembly work, without having to lay cables or ensure that the cables are laid without any problems. Depending on the manufacturer, the devices offer different transmission protocols or the option of integration into different wireless networks. The differences lie in the range and transmission security, among other things. In addition, there are models with or without feedback (monodirectional or bidirectional).With the single position switches from the eibabo® online shop, you can automate your production processes and thereby improve your efficiency. Since these switches are intended for industrial use, they are very robust, protected from dust and water and are particularly reliable.

Entrance panel - Depending on which doorbell system you have installed in your house, you have many options available to design the operation of the doorbell, not only visually but also technically. The simplest solution is certainly the classic doorbell button, which usually also has a field for writing the name. The multiple touch pads are a bit more extensive, on which different bells, for example those of an entire floor, are brought together. For the premium range, your eibabo shop offers you complete and elegant front-door stations made of stainless steel, which can optionally be equipped with video and light functions as well as with bus installation technology. If you want your system to be even larger, we would also be happy to supply you with solid doorbell stations for entire households and with an intercom facility.Catalogue content:In this eibabo® catalogue Communication technique > Push button panel door communication you will find items from the following product groups:Item overview:Access controlAudio moduleBell buttonBell moduleBell panel for door communicationBell plateButton moduleCall speakerDoor bellDoor communicationDoor intercomDoor stationDoorbell panelDoorbell plateEntrance panelEntrance panel door communicationExternal stationFingerprint moduleFront panelIntercomIntercom moduleObject door stationOutstationPush button panel door communicationStainless steel door stationStatus displayV2A door stationWeather protection rooffrom the following manufacturers:Manufacturer overview catalogue Entrance panel:Busch JaegerComelit GroupElcomGrotheLegrand SEKONovarRittoTCS
Tactile sensor - Smart, individual, simple, extravagant, futuristic - touch sensors, also known as KNX buttons, like to attract admiring glances and their modern design alone suggests to every user that this is more than a conventional light switch. Rockers, glowing LEDs, small symbols or even LCD displays give an idea of the numerous functions hidden behind many an installation. In addition, there is often a very noble selection of materials such as high-quality metal, acrylic or glass, which always exudes a touch of extravagance. But why are multifunctional touch sensors needed and how do you use their potential optimally? We give you a brief insight here.The basics in a nutshellTouch sensors are multifunctional control elements for the smart home.The design and function selection is huge, from a single button to a control center with 12 or more buttons, everything is possible.You can use it to control, for example, the light, its dimming, blinds, heating, entertainment center, door opener and all other devices in your home network.The button functions can be assigned individually and can be easily reprogrammed if necessary.Integrated LEDs or other displays often show the respective operating status or provide information about errors.   What is a touch sensor or a KNX button?You can operate the end devices integrated in your smart home network with a touch sensor or a KNX button. This can be blinds that you can raise and lower - light that you dim - the heating that you regulate or completely individual, user-defined scenarios. Depending on the model, operation is optically individual. In general, it is operated using a different number of buttons or rocker switches and/or even displays.The different types of KNX buttonsUsing a KNX universal button interface, you can basically turn any conventional button into a KNX button. These interfaces are installed in a deep device box behind the standard button and thus take on the task of the binary input, which converts the classic switching processes into KNX signals.Which doses are suitable?To do this, use a branch switch box with 4 screw domes or a deep switch box or an electronics box. Use our eibabo® search to quickly find the right item.This solution is particularly suitable for the standard application 'basic lighting' per room (see: 'What are standard applications?') or for the modernization of existing installations as well as for inexpensive and functionally manageable system extensions.'Real' KNX tactile sensors are much more complex and range up to control elements with elegant touch displays. Temperature sensors, LED displays and background lighting are often already combined in one device. In contrast to the simple interface variant, there is often the option of providing each key with additional functions, which are then triggered, for example, by a long press, double-click or even triple-click. TIP:We recommend planning well in advance so that you can later fit all the functions you need into your keypad. While some KNX push-button sensors require a separate bus coupler to which they are plugged, the bus coupler is already integrated in others. The eibabo® technology store also has both complete KNX pushbuttons and pushbutton sensor modules. The latter is 'only' about the technology and you can choose a matching design cover yourself. The possibilities are diverse - you can choose exactly what suits your project.The advantages and disadvantages of tactile sensorsThe central control of a large number of actions on different end devices is certainly the greatest advantage. The plus in comfort is combined with the flexible options for changing and expanding a well-planned setup. The disadvantage is certainly the slightly higher acquisition costs of a smart home solution compared to a conventional electrical installation. In the case of units with many keys and each assignment with different control variables (print, double-click), the overview of all the functions and their control can easily be lost.Unusual application examples in everyday lifeWe have already mentioned a few classic use cases. In the course of our more than 25 years of work, we have also been able to implement 'very special' projects. It starts with the smart opening and locking of the cat flap in the basement, continues with the choreographed lighting of exterior facades and doesn't end with the automatic pool cover, the fully automated aquarium or the heated driveway in winter.  You want to know more? We answer frequently asked questions.Nobody knows everything and sometimes there are small ambiguities that prevent us from correctly grasping connections or from deciding on one or the other product. You may also find an answer to your question in the following topics.How are the KNX devices programmed?Many interested parties are quickly startled by the term 'programming', but it's not that difficult at all, because it's not actually programmed with the 'ETS', but assignments and parameterizations are carried out.What does ETS mean for KNX?The term ETS (Engineering Tool Software) means that it is programming software for commissioning the KNX devices. The tool is more of a software for parameterization and basically also suitable for laypersons with an interest in the logic of the KNX.No programming knowledge or programming language is required. If you are interested in the rather simple logical connections of the KNX bus, you are in a position to create a project. Of course, more complex projects require a certain amount of experience. We always recommend having the basic project created by an experienced system integrator. This allows you to easily change important parameters yourself later on, since many things change in the life cycle.Which touch sensor or KNX button should I buy?Well, we can't give a general answer to this question, but we can perhaps provide some impetus for decision-making. KNX push button sensors are available in a variety of designs. The manufacturers offer solutions for every taste. However, you should not only be guided by the optics. In addition to the optics, eibabo® also recommends checking the applications (parameters and functions) provided by the manufacturer for the ETS (Engineering Tool Software). Significant deficits can open up here in the course of a project if the beautiful button were not able to control the necessary actions correctly. Plan exactly which requirements you place on the respective push button sensor and then select a suitable model accordingly. NOTE:ETS is standardized software for commissioning the KNX devices and can be obtained from www.knx.org. With regard to the design, you should also rely on optics that have a positive effect in the long term and not follow every short-term trend, only to realize a few years later that the brightly colored displays and the LEDs for various status messages on the buttons in the wall were a bit too much of a good thing. It makes sense to ensure that displays can be dimmed or configured in different brightness levels and status LEDs can be configured and switched off. A timeless surface design, for example, has simple elegance, looks classy, is durable and has no playful rockers that could quickly gather dust.How do I recognize whether a touch sensor already has a bus connection?Some touch sensors already have a bus connection. If you're not sure, a look at the back will clarify.Image: KNX push button sensor - Jung 4047TSMA touch sensor is equipped with a bus coupling if it has a black and red (or gray and red) terminal for the bus on its back. This 4-wire terminal with plug-in terminal connection serves as a distributor for up to four KNX lines.How do I keep track of the individual functions of complex touch sensors?We would like to encourage you to think: Imagine you come into a room and have to press the small second rocker from the top left on an 8-way pushbutton sensor every day to switch on the basic lighting. It can quickly happen that you accidentally set the pressure point on the adjacent rocker and unfortunately operate the blinds at 11:00 p.m. Not to mention how a guest or child is supposed to cope with it.So it can indeed be a bit difficult to always steer correctly. But: The advantages of the KNX lie in the intelligence of the system, which is implemented by the system integrator based on their experience and your functional requirements. For this reason, you should arrange functions logically or thematically and, if necessary, group them on easy-to-use buttons. If necessary, it is advisable to divide standard applications and detailed circuits into different buttons at different mounting heights.What are default applications? What is the best way to implement this into the system?The first switch box is usually placed on the 1.05m upper edge of the finished floor. At this point you should mount a conventional double button and connect it twice to the bus via a very inexpensive KNX button interface. Of course, you can also mount 2 or 3 double buttons and integrate a 4-way or 6-way KNX button interface. A deep switch box or electronics box is installed as a flush-mounted box in order to be able to place the small button interface behind the double button.Here you save!Combine a KNX button interface with a conventional double button.With the conventional double button, you have more choice in the design of the switch range and, in the event of defects or design changes, you can obtain a lifetime replacement without having to reprogram. You can assign the most important and most frequently used basic lighting to this button or parameterize the button or the button interface with light scene recall. A beautiful flat switch is also very easy to use for guests and children.What is meant by detailed switching on the KNX button?You should mount detailed circuits of the certainly many functions in a room on the 1.60m upper edge of the finished floor and call them up from a room controller or multiple push-button sensor with an optionally integrated room temperature controller (see also our multiple control unit catalogue). A room temperature controller already requires this mounting height for optimal control. At this user-friendly height, you can then carry out all additional controls for additional lighting, blinds, roller shutters, entertainment, etc.Touch sensors wear out very quickly! Is that correct?Like all other technical components that are used more or less every day, tactile sensors and control points in general are subject to a certain amount of wear and tear. However, this is no different than with conventional buttons or switches. It is possible that individual parts that have been in use for a decade are then worn out.Does it make sense to control the heating using touch sensors?Definitely, as a rule, individual room heating controls are also required for KNX installations. In terms of value for money, the combined buttons with room temperature controllers are the best choice, also in terms of user-friendliness.Which manufacturer offers the most beautiful and best KNX buttons?Beauty is in the eye of the beholder, we won't take a position on that. In terms of quality, however, all brands perform very well. There is no such thing as the 'best' touch sensor. Each manufacturer has its individual strengths in terms of applications (parameters and functions). eibabo® offers switches from all brand manufacturers (from ABB, Berker, Busch-Jaeger, Gira, Hager, Jung, MDT, Merten to Siemens). Select KNX push-button sensors in the following versions: KNX push-button sensor, KNX sensor unit, KNX wall sensor, KNX room control unit, KNX push-button sensor module, KNX push-button sensor extension module, KNX push-button 1-fold, KNX push-button 2-fold, KNX push-button 4-fold, KNX push-button 5-way, 6-way KNX button, 8-way KNX button, KNX control panel, KNX button with bus coupler, KNX button module, KNX touch sensor, KNX button sensor plus, KNX glass button.  Catalogue content:In this eibabo® catalogue Installation bus systems > Touch sensor for bus system you will find items from the following product groups:Item overview:Adapter frameBuilding controlBus couplerBus technologyButton couplerCabel CanalColor displayContactlessControl elementGlass buttonGlass sensorGroup button bus couplerLight scene touch sensorsNickel metallicOutdoor areaPendulum fanReceiving sensorRemote controlRemovable fanShutter buttonSingle rockerSplash proofTactile sensorsTemperature sensorTitle blockTouch sensorWireless pushbuttonWireless solutionfrom the following manufacturers:Manufacturer overview catalogue Tactile sensor:ABBAVM ComputersystemeBerkerbticinoBusch JaegerEatonElsnerESYLUXGiraHagerIssendorffJungLingg & JankeMaicoMDTMertenRopagSiemensTheben
