Rope light - LED strips are considered flexible and energy-saving lighting alternatives. But what criteria do I use to select an LED strip from a multitude of offers? How long does an LED strip light last? Many questions, to which we will give answers in the following article.Why are LED strip lights so popular?When LED technology became suitable for the masses and was available inexpensively everywhere, completely new and very flexible possibilities for the decoration and lighting of houses, apartments and other areas of life opened up for us consumers. Small dimensions, flexibility, enormous service life, good light output and different color rendering are still the most important positive properties of LED light strips. Of course, saving high energy costs and the lack of alternatives to LEDs also play an important role. Constant competition between manufacturers also leads to falling production costs and end consumer prices. Many of the products are operated with 12 V or 24 V and are therefore not dangerous in use.Where are LED strips used?The areas of application of the LED strips are hardly limited. Thanks to the use of high-power LEDs, you can use the products as the main light. But LED strips are also ideally suited as decorative lighting on and in cupboards, in various niches or to illuminate the work area in the kitchen. In the commercial sector, you can use it to illuminate goods and offers in shop windows and shelves. TipUnder no circumstances should LED strips be severely bent or kinked. This can break circuit paths or damage LEDs, resistors and contacts. You can achieve breathtaking lighting effects with RGB strips or color-changing strips. Typically, the color and brightness of such a band is controlled by a remote control. You can adapt the lighting to your current mood, especially in quiet places. Of course, waterproof versions are also available. You can light up gardens, facades, terraces or use them to simulate the daily routine in the aquarium. Car lovers use colored LED strips to illuminate the underbody of the car, the rims or the license plate. In architecture, planners set great accents with LED strips. Creative solutions include colored facades and window frames, indirectly illuminated walls or illuminated baseboards.In other words: due to the wide range of design options, LED strips have become indispensable and are used in the design of almost every interior.Image: EVN SB542430509902 LED stripWhat is the difference between LED strips?The offer is huge. The Internet is full of special offers, which are made in China with the cheapest components, imported in huge quantities and sold at cheap prices. We also offer hundreds of variants here in the eibabo® shop, but the majority of them are from well-known manufacturers. It is not that easy to find the right product for individual use. So what selection criteria should you consider?Does the product come from a well-known manufacturer?How long is the lifespan?What power supply is required?Do I want monochrome or colored LEDs?Which tape is best?How many LEDs should be installed per meter?Does the product have to be waterproof?What length do I need?Does the tape have to withstand special conditions such as heat or mechanical loads?and much more So pay attention to the information in the product descriptions and put the price in the background. Why? You will find out in the next section.What affects the quality of an LED strip?All tapes look more or less the same and the reason for a price difference is often not apparent even at second glance. However, what matters most to you as a consumer is its lifespan, delivering a constant level of brightness over that period, and its power consumption. The heart of an LED is its crystal. This is created as part of a complex process that requires a lot of technology, knowledge and experience. Few companies rise to the challenge of producing perfect crystals. However, these are the basis for a high-quality end product. The lifetime of such a crystal is determined by its degradation. definitionDegradation is the aging process of the crystal, which causes an LED to become progressively dimmer over its life cycle. Degradation leads to a drop in luminous flux over time. With high-quality goods, the luminous flux drops by around 2% for 10,000 hours of operation. Inferior LEDs lose up to 20% of their luminous flux in the same time. However, this development does not only depend on the crystal, but also on the design of the LED body and its connections. An LED gets very hot during operation and the better the heat is dissipated, the more sophisticated the housing and the longer the service life of the LED. The design of the contact connections is also important. In a circuit there are usually several LED chips in series plus resistors. Surely you have already seen that with poor-quality soldering of the chips, the entire serial circuit on a certain section of the LED tape fails, or individual colors stop working.Already knew?LEDs do not emit white light. White light is created from the mixture of equal parts of all spectral colors. If none of these colors dominates, the light appears white, more precisely not colored.Depending on the type of tape, the white light color is mixed from red, green and blue light. However, this mixed white looks very unnatural. So-called RGBW tapes therefore have an additional LED, which emits high-quality white light. In other words: the production of LEDs with white light is complicated. It is usually formed by passing blue light through a yellow phosphor. Depending on the phosphor, the 'white' LED lights up more yellowish or more bluish. It is therefore important before manufacturing an LED strip to select and calibrate the individual LEDs according to various criteria. This step is time-consuming and is not carried out by all manufacturers. In particular, because the manufacturers of LED strips are not necessarily the producers of the LEDs. The use of different LEDs from different batches or producers leads to an uneven light pattern of the white light. With LED strips, the uniformity of the white glow is therefore a quality feature.power adapterThe power supply should provide enough power for the LED strip. An LED light strip with a length of 5 meters and a power consumption of 20 watts per meter requires a 100 watt power supply. Please plan an additional 10% reserve.An LED emits light in a specific direction. In order to achieve uniformity here too, lenses and other optical elements are used. The higher the quality, the better the color rendering and the lower the loss of luminous flux.How do I know if an LED strip is high quality?Now you know how (at least in part) the price difference comes about. If you want to enjoy your LED strip for a long time, invest a few euros more. The difference isn't huge, but it will save you trouble and early repairs. You can use the following tests to better assess the quality of an LED strip:tip 1Check the 'white' light the tape produces. Blue, yellow or reddish deviations should not occur. Contrasting sunglasses may make it easier to spot differences.tip 2A noticeable decrease in brightness on the last LEDs of a band indicates poor quality of certain components.tip 3If it is not possible to test the LED strip before buying it, a look at the soldering points between the LEDs and the carrier material will help. All solder points should look the same. Make sure that the conductor tracks on the carrier material are as wide and thick as possible. In the case of inferior goods, conductor tracks that are too weak lead to an increased voltage drop and thus to differences in brightness.tip 4Choose products from companies with many years of experience in the field of household lighting, including LED. They value a good reputation, have long-established contacts with suppliers and are unlikely to produce inferior goods. Pay attention to the guarantee.  Catalogue content:In this eibabo® catalogue Luminaires > Light ribbon-/hose/-strip you will find items from the following product groups:Item overview:Adhesive stripsArea lightBacklightingColor changeDirect lightFairy lightsFlex boardFurniture mounted lightFurniture recessed lightGroove lightHeadlightInterior lightLight barLight ceilingLight coveLight stripLine of lightLinear systemOutdoor areaQualityflexRecessed ceiling lightRecessed ceiling spotlightRecessed directional spotlightRestaurantRope lightShadow gapSpotlightHeadlampTunableWhitefrom the following manufacturers:Manufacturer overview catalogue Rope light:ArcliteBarthelmeBrumbergEOS SaunatechnikEVNHellumHeraHoubenLEDVANCENeuhaus LeuchtenPhilips LichtRZBScharnberger+Has.Schmitz-LeuchtenSLVTehalit
Cable run - cabinets - Countless cables and lines are laid in control boxes and server cabinets. In order to ensure safe installation and always keep track of things, it is advisable to lay and fix the cables and lines sensibly. On the one hand, wiring ducts have proven themselves for this purpose, but their use does not always make sense because, for example, there is a lack of space. Alternatives to this include wire, hose and cable holders, cable clamp rails, cable clamps, marshalling panels or cable brackets. This enables cables and lines to be fixed and bundled quickly and inexpensively. Your eibabo online shop offers you numerous products for cable routing so that you always have an overview of your installation and that maintenance, changes or additions can also be easily carried out by third parties.Catalogue content:In this eibabo® catalogue Energy distribution systems > Cable guide for enclosures/cabinets you will find items from the following product groups:Item overview:Cable bracketCable clampCable ductCable guard railCable guideCable guide for cabinetsCable guide for enclosures/cabinetsCable hoseCable management bracketCable management for cabinetsCable railCable routingCable troughCabling panelControl cabinet cable routingControl cabinet wiringFiber circular profileFiber Optic Cable ManagementFibre optic cable guideHammer head profileHolder for protective hoseProtective hoseQuadrant profileRailSandwich cable guideSpiralized cable routingStrain relief clampVertical cable management bracketfrom the following manufacturers:Manufacturer overview catalogue Cable run - cabinets:3MABBABNAssmannBachmannCommScope EMEACommScope/AMP NetconnCorningDätwylerEatonEFB-ElektronikEnocHagerHellermann TytonHenselIcotekMennekesMetzMurrelektronikMurrplastikPanduitReichle & De-MassariRittalSchneider ElectricSchäfer IT-SystemsSiemensSpelsbergStriebel & JohnTelegärtnerTelevesVertiv
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.

Logic module - What is a KNX logic module and what options does the device offer when linking simple and highly complex functions? Why do we recommend logic modules as a useful addition to any KNX system? Find out here.KNX is the standard protocol for smart home and building automation. A system equipped with KNX technology enables you to control all connected devices in your household via a touch panel or remotely. The KNX technology is used not only in private homes or shops, but also in industrial buildings, hospitals, schools, high-rise buildings, universities, yachts and ferries and other facilities. The KNX automation system in residential or industrial buildings connects a large number of devices within the same facility. This allows information to be exchanged very quickly and maximizes efficiency in the workplace. There are hardly any limits to the size of a system and its complexity. KNX can be connected to different systems like BACnet, LON, LCN, RS485, LoRa, NB-IOT, Zigbee and others. This creates almost unlimited possibilities. Changes and extensions are possible at any time, quickly and inexpensively. The KNX automation makes our life more comfortable because it is:flexible - Almost all functions in the house can be controlled via KNX. Numerous brand manufacturers offer a wide variety of compatible devices.User-friendly - All electrical devices are easy to control. All control modules can be operated manually.safe and secure - the KNX system is not based on 230V, but on harmless 24-30 V. With the KNX Secure function, the system is particularly secure. With the KNX technology, the house, property and outbuildings can be controlled and monitored automatically. The use of additional control centers is not necessary. The KNX system fulfills a large number of functions, for example lighting, air conditioning and security systems. Work steps and daily routines are accelerated and the energy in our living space is used more efficiently. Easy installation:As series installation devices, logic modules are quickly clamped onto the DIN rail. The KNX connection is made using a special terminal. In order to create a perfect setup, numerous primary and secondary components can and must work together in a system. This includes KNX logic modules. These are always used when the installed KNX devices lack the necessary logic functions for specific tasks or higher-level central control and regulation tasks are required. As a modular installation device with a width of 1 to 2 modular widths, logic modules and scene modules/event modules also fit into small installations. An additional power supply is not necessary. The device draws its energy from the KNX system.What are KNX logic modules used for?KNX logic modules are a very useful and important addition to any KNX system. This means that additional functions can be reliably mapped. With the help of KNX logic modules, you can define a wide variety of dependencies and logically link group addresses. It is possible to implement simple and highly complex functions, from the alarm system to meter monitoring. You always remain decentralized and independent of central server components.Image: MDT SCN-LOG1.02 logic moduleKNX logic modules offer linking functions with:all common logic gates, filter functions, time functionsTime modules with comparison function and run-on timeconverters and multiplex modulesdelay blockslight scene modulesMonitoring functions of bus participantscomplex specific blind controlshour counterstemperature switches or temperature modulesConverters for converting telegramsSequencer modules for generating multiple telegramsand many more TIPEven if a KNX server/visualization is used, we recommend a KNX logic module for failure monitoring or for relevant functions that must be ensured in the event of a KNX server failure.You are still not sure what practical use logic modules have? We will show you with a very simple example:Suppose you have a small pond with a fountain on the patio of your house. Now you want the fountain to be running when you are home in the evening. The easiest would be to turn it on and off manually. No automation is used here. Using a timer is a bit more convenient. This means that the fountain runs in the evening after work, for example from 5 p.m. to 9 p.m. However, this is not yet intelligently automated. If the fountain's power supply is connected to the KNX bus, you could set the switch-on time in the evening and let the fountain run until sunset. But what if you sit longer on your terrace at the weekend and don't want the fountain to switch off when the sun goes down. This is where the logic module comes into play. In addition to timing and sun control, you can now command the fountain to keep running as long as the patio lights are on.How are KNX logic modules programmed?The KNX logic module is usually parameterized via the ETS (Engineering Tool Software). Complex KNX logic modules are processed using a simple graphic editor, which also enables laypersons to easily program and commission them. These logic modules often require free additional software/plug-in provided by the manufacturer.Are there different KNX logic modules?eibabo® has a large portfolio of KNX modules that are designed for a wide variety of tasks. These include KNX logic modules, KNX logic building blocks, KNX security modules, KNX application building blocks, KNX time building blocks, KNX logic controls, KNX link building blocks, KNX monitoring building blocks, KNX function modules, KNX scenes/event building blocks, KNX visualization servers and KNX logic controllers. When buying, make sure you choose high-quality goods from manufacturers such as ABB, Berker, Buderus, Busch-Jaeger, Hager, Jung, MDT, Merten, Schneider-Electric or Siemens.  Catalogue content:In this eibabo® catalogue Installation bus systems > Logic component for bus system you will find items from the following product groups:Item overview:Alarm moduleApplication controllerApplication moduleBus technologyControllersFunction moduleLogic moduleMonitoring moduleSecurity moduleSocket coverZone terminalfrom the following manufacturers:Manufacturer overview catalogue Logic module:ABBBUDERUSBusch JaegerGiraMDTMertenSchneider ElectricSiemens
Pressure switch - Would you like to control switching processes in a technical system that are triggered by changes in the pressure of a gaseous or liquid medium? Then you need a pressure switch. Here you can learn a little more about the history, the tasks and the operating principle of pressure switches. Inexpensive and reliable pressure switches for switching valves or pumps are available here in the eibabo® online shop. Choose a model that suits your system from our range.What are pressure switches?Pressure switches are used to automate a pump or compressor. The basic principle of these switching devices is that connected devices:switched on when the pressure falls below a set limitoff when the upper pressure limit is reached Image: Eaton MCSN11-V pressure switchPressure switches have many names. The following terms are very common:Differential pressure switch, pressure limiter, pressure controller, pump relay, water pressure switch, air pressure switch or compressor switchThe devices are used, for example, in liquid tanks or gas tanks in which the filling level or the internal pressure of the medium contained therein is to be monitored. This ensures that certain values are not exceeded or fallen below. Alternatively, when a critical value is reached, switching processes are triggered in order to restore the desired or programmed normal state. A distinction is made between mechanical and electronic pressure switches, which offer individual advantages depending on the desired area of application.The history of the pressure switchIn the past, pumps and compressors were switched on and off mechanically and required constant human intervention. In the early 1930s, August Frede Maschinenfabrik (today: Condor-Werke) developed a simple and functional device that was equipped with a membrane and worked according to a spring principle. This first pressure switch should automate the switching on and off of pumps or compressors. In 1935, the company received the world's first patent for a diaphragm pressure controller for the automatic control of pumps. To this day, Condor-Werke is one of the global market leaders in the development and production of pressure switches.What are the advantages of a pressure switch?A pressure switch allows full automation of the start-up and shut-down process, eliminating the need for human involvement in managing the pump or compressor. An automatic shutdown when the upper pressure limit is reached guarantees the safety of the respective system. If pumps or compressors only work within a certain pressure range due to intelligent switching processes, energy costs can be significantly reduced and resources saved. TIPBe sure to note the installation location and, accordingly, the moisture protection of the pressure switch. In addition, pressure switches are very reliable and durable.The mechanical pressure switchDepending on the design, pressure switches can work mechanically or electronically. Mechanical type devices are more common due to their reliability, durability and simplicity. The mechanical pressure switch can be installed directly on site with minimal effort.NoticeHigh-quality pushbutton switches have non-stick silver-plated contacts, a high-strength diaphragm and fine-tuning capabilities. Especially with cheap goods from the Far East, the lack of these properties can lead to failures and unreliable switching operations. Here in the eibabo® online shop you only get reliable quality goods from well-known brands.The functional principle of a mechanical pressure switch is essentially based on the combination of a membrane with a block of adjustable springs. The pressure of the working medium is transmitted through the diaphragm to the working pressure setting springs by means of nuts or screws. A differential pressure setting spring measures the value of this compression. If the compression of the working pressure setting springs exceeds a certain value due to the pressure of the diaphragm, the differential pressure setting spring opens the contacts in the contact block and the pump or compressor is switched off. When the pressure drops, the tension in the springs relaxes again and the compression decreases. The mains contacts then close again and the connected device is switched on again. Depending on the version of the pressure switch, there may be additional outlets for connecting a pressure gauge and safety valves.The electronic pressure switchAn electronic pressure switch is actually a complete pump controller. As a rule, these devices include elements for soft starting, protection against dry running, as well as ways of setting the upper and lower thresholds of the operating mode of the pump or compressor. The advantages compared to a mechanical pressure switch are the smaller dimensions and the setting principle. Sensitivity adjustment screws are located on the electronic pressure switch body.How do I protect myself from my system running dry?The cause of failures in the operation of pumps or compressors is often the lack of the required working medium in the system. This problem is annoying and affects the reliability of all components. Idling leads to overheating or damage to parts and the associated failure of the entire system. To avoid this, when choosing a pressure switch, please consider the characteristics and allowable ratings for the operation of your pump or compressor. You avoid the danger of idling as follows:Buy a device with dry-running protection. These devices are a bit more expensive, but respond very effectively to pressure drops.Invest in the installation of a controller that not only monitors the pressure. This would, for example, also switch on the pump if the actual values fall below the set target values. How do I choose a pressure switch?When choosing a pressure switch, it is necessary to determine the type of pressure switch, the required functionality and the operating pressure:Should the switch monitor the pressure of liquids or gases?Does the switch have to be able to withstand chemical compounds?In which key figures is the working pressure range?How is the power supply designed for the switch (voltage, number of phases, current)?What sizes are required for the flange connections?What additional components and options are desired? Examples of this would be: start button, thermal relay to protect the electric motor, dry running protection relay for pumps, relief valve to make starting compressors easier and so on. When installing a high-quality pump, please remember that the pressure switch should also be of the same quality. This is the only way to ensure reliable operation. by the wayThe manufacturers of high-quality devices carry out long-term tests with the pressure switches in the laboratory in order to guarantee more than half a million switching operations. Use our detailed search to select your pressure switch. There you can precisely set the parameters of the switch you want and filter accordingly.  Catalogue content:In this eibabo® catalogue Low-voltage industrial components > Pressure switch you will find items from the following product groups:Item overview:Compressor switchCylinder switchDifferential pressure switchPressostatPressure limiterPressure monitoring devicePressure regulatorPressure sensorPressure sensorsPressure switchPressure transducerPressure transmitterTwo-position controllerVacuum monitorVacuum switchfrom the following manufacturers:Manufacturer overview catalogue Pressure switch:Alre-itBaumerBourdon-HaenniCondorDoepkeEatonElsterEndress + HauserHeliosHoneywell FemaIfm ElectronicIpf ElectronicJumoMaicoNE-MARockwellSchneider ElectricSickSMC Deutschland
Crimping tool - Tired of frayed cable ends? Would you like to securely attach cable lugs or ferrules so that your wires are permanently fixed in screw terminals or spring terminals? With the high-quality pressing tools from the eibabo® shop, well-functioning contact connections can be made in no time at all. Manual, battery-powered and electric, hydraulic or pneumatic crimping tools are in daily use and are part of the basic equipment of a good electrician. Even the private do-it-yourselfer achieves better results if the tools used are easy to use and precisely cut, strip or press. In this article, we will introduce you to the most important pressing tools and give tips on what to look out for when buying one. Here you will find numerous high-quality crimping pliers, cable lug pliers, notched pliers, contact crimping pliers and other crimping tools at top conditions. All products in the shop are often used by us and our partners for years and can be recommended without reservation.What is crimping?Most of the items presented here are special tools for performing a wide variety of activities. But they all have one thing in common: the tools create a connection between two components by plastically deforming them. This deformation can be caused by pressing, squeezing, piercing, flanging or folding and is referred to as 'crimping'. All of these tools are by definition crimping tools, although 'crimping pliers' are often referred to as a separate product group. We mainly use the term 'press tools'.What is the difference between pressing tools?Pressing tools are different devices that permanently connect two materials or components through deformation. One of the most common applications is attaching connectors to the end of electrical wires. But many pressing tools are multifunctional. Depending on the application, you can also bend, cut or strip materials with it. The tools are designed in such a way that they are suitable for specific cable diameters, conductor cross-sections or pipe sizes in order to guarantee secure connections. There is typically no provision for the connections to be released.The biggest difference between the individual pressing tools lies in the type of function or operation. Each type has its advantages and disadvantages. When machining smaller components, for example, precision is often important. It is best to use a manually operated pressing tool here. When you need more power, hydraulic and electric models make your job easier.hand toolsManual devices are often small, light and intended for the tool case. These are in the form of pliers and are suitable for daily use on the construction site and for processing smaller components.Equipment for the workbenchBench tools are the opposite of manual tools. These are big and heavy and have power. Permanently mounted on the workbench, these can be operated electrically or manually with levers and rotary devices. Good to knowWith the manual and battery-operated devices from our shop, you are already optimally equipped for conventional electrical installations. More complex tools are more for commercial and industrial use. Electrical appliancesElectrically operated pressing tools are usually equipped with rechargeable batteries and do the work without much effort. Wired models are rare. Although these devices are not for the pocket, they are intended for mobile use on the construction site.Pneumatic pressing toolsPneumatically operated pressing tools require little effort. The compression force is provided by compressed air. These devices offer maximum performance and are suitable for demanding installations, repair services and maintenance work. Here we distinguish between small mobile devices and permanently installed models for the workshop.Hydraulic pressing toolsThese models are similar to the pneumatic variants. Here, too, there are mobile and fixed pressing tools. However, the compression force is provided by hydraulic fluid.The pliers for ferrulesA bare and unprotected wire end is not optimal for the connection with screw terminals, spring terminals or similar. This applies in particular to flexible strands, which consist of many thin wires. These ends will fray in screw terminals, become damaged, and lack the strength to be plugged into spring terminals. Wire-end ferrules were developed for this purpose, which give the wire a firm shape and improve the resistance of the wires to oxidation. This increases the longevity and reliability of a connection. A ferrule is a soft metal tube that is crimped onto the end of a stripped wire. Most ferrules are made of copper and are tinned, sometimes gold or silver plated. This serves to protect against corrosion. The diameter and length of a ferrule is determined by the thickness of the wire.NoticeFerrules are color coded for the maximum wire sizes. However, there are different, sometimes contradicting color codes. Please ensure the correct size to ensure secure connections.A ferrule is usually wider on one side to make it easier to put it on the wire. This side is covered with a plastic cable entry sleeve (protective collar). The protective collar serves as a transition between the core insulation and the ferrule. The ferrule pliers only crimp the copper part with the wire while leaving the plastic sleeve around the insulation undamaged.cable lug pliersIn addition to ferrules, cable lugs are often attached to the wires. Cable lugs are similar to ferrules. While a ferrule only encloses and protects the wire, cable lugs also have a special attachment option for the cable. This can be, for example:Ring Eyelets: The connection part consists of a flat contact surface and is in the form of an annular eyelet completely closed in a circle. There are versions with one hole or multiple holes. Cable lugs with multiple holes prevent rotation or movement of the cable lug.Clevis: The connecting portion of a fork is in the shape of a two-pronged fork. The connection point here is not a circular closed hole, but open on one side.Special shapes: There are cable lugs in special shapes, such as flat contact surfaces (with and without side guides) for sliding onto suitable mating contacts. TIP:Multifunction tools offer the option of changing the press inserts. Among other things, this allows you to process various wire-end ferrules and cable lugs with just one device. Choosing the right cable lug (and thus the choice of the correct cable lug pliers) also depends on the conductor class. You can find more information in the category 'cable lugs'.RJ45 crimping pliersRJ45 crimping pliers are specially designed for processing non-assembled network cables and telephone lines. The pliers are used to press the Western plug (RJ45) with the inserted wires of the cables. These pliers often have an integrated flat cable cutter and a possibility for stripping.Are there pressing tools for extremely thin wire cross-sections?Working with particularly thin cables does not forgive any mistakes. Problems can even arise with the classic manual press tools. For such requirements, use a press tool with a ratchet lock. This locking device in connection with an automatic cross-section adjustment controls the pressing process. Human errors are excluded and uniformly controlled pressing results are guaranteed.Can I squeeze wire ends with pliers?The pressing and squeezing of ferrules or cable lugs with conventional pliers is not recommended. You cannot produce a safe, clean and durable cold-weld joint with it. A bad crimping result means, for example, that the sleeve or the cable lug is loose and comes off. Air and moisture could enter the connection. Then corrosion occurs and the electrical conductivity would be impaired.Image: Klauke K 05 D pressing toolIsn't soldering much more stable than pressing?A proper press connection usually provides a stronger and more reliable connection than soldering. Soldered joints can break under certain circumstances, while pressed cable ends are significantly more robust. Press connections can be made more easily with cables and lines that have already been laid. Soldering in dark and hard-to-reach places is difficult.How do I release a press connection?It is not intended to release a press connection again. If you undo a press fit, the second try is unlikely to hold reliably. In these cases, shorten the cable or line and make a new press connection.Which pressing tools are the best?Professionals and ambitious do-it-yourselfers will find professional-quality crimping tools and tools for crimping, cutting and stripping at eibabo®.

Earthed plug - Electricity is essential in all areas of daily life these days. Whether household appliances, entertainment or even driving a car - nothing works without electricity. But not only the use of electricity is important, the secure connection of the electrical devices is also crucial. SCHUKO plugs are used here. These plugs are reliable and guarantee a stable connection between the devices and the mains. SCHUKO is the abbreviation for protective contact and a system of plugs and sockets. The SCHUKO plug is part of this plug-in system, which can be plugged in and unplugged under electrical voltage or load.What is a SCHUKO plug?SCHUKO is a system of mains plugs and sockets of the CEE 7/4 standard. These are also known as Type F connectors. Type F plugs are used, for example, in Germany, the Netherlands, Portugal, Austria, Spain, Sweden, Finland, Norway and many countries in Eastern Europe.Already knewThe grounded SCHUKO plug in its current form was patented in 1929 by Siemens-Schuckertwerke AG. This was preceded by a patent by Albert Büttner, who designed the basic shape of the plug and held all the necessary parts together with just a single screw.SCHUKO plugs and the associated sockets are usually equipped with a protective earth and are intended for use in 230-volt networks with a current of 16 amps. SCHUKO plugs and sockets are unpolarized. That means: outer conductor and neutral conductor are randomly connected. In addition to the outer conductor and the neutral conductor, the system has a green-yellow protective conductor, which takes over the protective earthing with two flat contacts at the top and bottom of the plug. When plugged into a socket, the SCHUKO plug closes the connection cavity of the socket and thus prevents contact with conductive components when making contact. First, a ground is established between the flat contacts of the plug and the grounding terminals located in the socket. Only then do the phase conductor connections and the neutral conductor connections come into contact with one another. And it is precisely this fact that is special about the SCHUKO system and gives it its name: the protective contact connection diverts dangerous voltages as soon as the electrical circuit is closed by the other two poles. This design with leading protective contact ensures that there are no dangerous voltages on accessible parts of the device.Additional lateral guide slots in the socket are required for reasons of stability. These enable the use of large and heavy SCHUKO plugs, for example with a built-in transformer or timer.Image: Mennekes 10837 Schuko plugBasic information on the typification of plugs and socketsThe plugs and sockets that exist worldwide are numerous and correspondingly different. Their design and structure is often historical and adapted to the conditions of the power grid in the respective region. Worldwide, we distinguish between two standards for wired AC transmission. On the one hand, this is the 230 volt standard with a frequency of 50 Hertz / 60 Hertz. On the other hand, it is the 110 volt technology with a frequency of 50 Hertz / 60 Hertz. Based on this, individual countries and manufacturing companies began to offer their own connectors. This led to a high degree of individualization. The introduction of a globally standardized plug system failed on the one hand because of political sensitivities, wars and conflicts and, of course, because of the two already established transmission standards. Because there would be a risk of devices being damaged or short circuits or fires occurring if a device were connected to a network with a voltage other than its nominal value. As a result, the development of adapters and transformers was accepted instead to achieve cross-system international compatibility.NoticeThere are currently 15 plug / socket standards worldwide, referred to as plug types A to O. Here in Central Europe, types C, E and F are used, some of which are also compatible with each other.The Type-C plug is an unearthed two-pronged plug that used to be standard in most European countries as well as in the countries of the former USSR. This type is considered the forerunner of today's French type E and the German type F. Type C plugs are still often found in the form of flat plugs on many devices such as fairy lights, floor lamps, razors, hair dryers and other small household appliances. In the international CEE system, this plug shape is referred to as the CEE 7/16 standard. Type C plugs fit perfectly into a Type F SCHUKO socket.With the French type E plug, there is a grounding contact for the protective conductor in the center above the pins for the phase conductor and neutral conductor. The counterpart to this is a pin that protrudes from the French Type E socket. Classic plugs of this type are usually round and do not fit into the Type F SCHUKO socket because the lateral guide grooves and the recess for the earthing contacts attached at the top and bottom are missing. However, these are only very rarely found and are increasingly being replaced by CEE 7/7 plugs, which fit both type E sockets and type F SCHUKO sockets.The German Type F SCHUKO plug is widely used throughout Europe, as well as in Russia, Belarus and Ukraine. This is characterized by the grounding clamps at the top and bottom and by a guide groove on the right and left. In the international CEE system, this plug shape is referred to as the CEE 7/4 standard and is not compatible with the French Type E socket due to the lack of a recess for the grounding pin. This is why it is now considered obsolete. In the course of a homogenization of the European market, this plug is often replaced by the CEE 7/7 plug, which is a hybrid E/F plug. The CEE-7/7 SCHUKO plug is therefore the current, grounded and universal continental European standard:with grounding clips on both sides to match with Type F socketwith a socket contact to accept the ground pin of the Type E socket  by the wayThe socket of the SCHUKO socket is set back by 15 mm so that there is no risk of electric shock if the plug is partially inserted. Both the SCHUKO system and the French counterpart are designed for a nominal voltage of 230 volts at 50 hertz. All components are designed for 16 amps as standard. At 230 volts, this corresponds to an output of 3,680 watts.What is a contour plug?In connection with SCHUKO plugs, we often hear the term contour plug. A contoured plug is a two-pole (i.e. unearthed) plug that has the necessary recesses for the German grounding clamps, the guide grooves and an additional hole for the French protective conductor contact on the rounded edge of the plug. The plug thus fits into both systems, but does not use the protective contacts.At eibabo® you will find not only classic SCHUKO connectors, but also 2KT SCHUKO connectors (for difficult conditions), duroplastic connectors, flat connectors, flat cable connectors and flat connectors. Rubber plugs and PVC SCHUKO plugs as well as assembly plugs, angled plugs and wall plugs are also available for the SCHUKO system. In addition to the protective contact plugs of the SCHUKO system, we also carry protective contact plugs of the Swiss system and the English plug system. Please noteSCHUKO plug connections are not always compatible with other safety plug systems. SCHUKO plugs from all approved and well-known manufacturers are offered here in the shop, including ABL Sursum, Berker, Bachmann, Merten, Mennekes, Gira, Busch-Jaeger and Apsa.  Catalogue content:In this eibabo® catalogue Domestic switching devices > Plug with protective contact you will find items from the following product groups:Item overview:Angle connectorBelgium clutchBelgium plugConnectorConnectorsDevice connectorElamide connectorEuropean plugFrance clutchFrance plugFrench plugHousehold plugProtective contactRubber plugSafety plugSchuko plugSocketsSolid rubber plugfrom the following manufacturers:Manufacturer overview catalogue Earthed plug:ABLBachmannBalsBerkerBusch JaegerE+P ElektrikElsproGiraHartingHirschmannJungKleinhuisLegrand BticinoMennekesMertenMeyerSchulteWalther
