Modular plug connectors

What are modular connectors? Where can I use these in my home, commercial or industrial installation? What are the benefits of modular connectors? Does the eibabo® shop offer inexpensive and individual connectors? We answer these questions in the following post. In the field of electrical installation, connectors are of particular importance. Using plug-in connections, it is possible to connect two identical or different cables or lines with one another in a form-fitting manner. Such connections can also be released again.

Modular connectors are constructed in such a way that they have properties in common with other components. These are, for example, the same installation dimensions or the type of connections and attachments. These work individually, but can also be combined with others within an assembly unit to form a larger whole or exchanged for one another. If you are interested in a flexible and modular structure for your electrical installation, browse through this eibabo® catalogue. Select the modular connectors that are right for you.

Why are there modular connectors?

The modern, modular connectors go back to the development of the American telephone system. The phone companies dominated the phone network for the first few decades and didn't allow third-party devices. This applied to both commercial and private use. To connect buildings and individual telephones to the network, bulky plugs were used, which had been in use since the 1930s. These had to be installed and maintained by specialist companies at great expense.

As the telephone system became more widespread, a way was sought to reduce the high service costs. These efforts resulted in a modular system of components for standard connections. These were smaller, cheaper and easier to install. As a result, a standard was established for the connection between the telephone company's equipment and the customer's equipment. These standard interfaces were known as Registered Jacks (RJ). The RJ interface specification includes:

  • the physical construction of the plug
  • the wiring patterns
  • the signal specifications

 

Registered jacks are identified by the letters RJ. Additional digits describe the type and its properties. Modular connectors and RJ connectors are common names for the same devices. The use of modular connectors has helped fuel the global development of voice and data communications.

How are modular connectors constructed?

Modular plugs consist of a plastic or metal housing. The housing encloses stamped metal contacts separated by insulating channels. The contacts in the plug match the contacts in the socket. Part of the housing can often be used to lock the plug-socket connection and serves as strain relief. A modular plug or socket is assembled into a cable using a crimping tool. Depending on the use, individual connectors can have an even number of two to ten contact points. For this reason, the widths of the two connecting bodies vary. Not all contacts have to be assigned a line. Telephone (RJ11) connectors typically use four to six ports. RJ45 Ethernet connections have eight ports. The specification details describe the wiring. For example, a 6P2C connector has six positions and two contacts. A four-position, four-contact connector is designated 4P4C.

 


TIP:

The specification given for the wiring does not define the purpose of the wires.


 

Modular connectors are also referred to as male or female. The male connectors are plugs or headers, the female ones are sockets or sockets. Some modular connectors supply low voltage AC or DC power to small electronic devices.

What are the advantages of modular connectors?

The biggest advantage of modular connectors lies in their standard use in communication and data transmission. The connectors are also used in production, in field installation and in the maintenance and repair of machines and systems. The advantages in production are:

  • low prices and constant availability
  • Assembly of plugs and cables without soldering
  • robust versions available for industrial applications
  • Possibility to use the sockets on boards by reflow soldering

 

The same advantages apply to installation and repair. In addition, value is placed on the following properties:

  • Simple cable assembly and replacement of old connections on site
  • quick assembly with simple tools
  • numerous wiring options

 

This avoids production downtime and increases the reliability of a system.

Where are modular connectors used?

The use of modular connectors allows you to individually configure contact connections. Reliability and ease of use have made modular connectors an easy solution for many applications. The most common applications are data networks, telecommunications and low-speed serial connections. Due to the efficient and compact designs, these are also used as alternatives for bulkier and more expensive connectors in various products. Modular connectors are used worldwide and are among the essential components in data transmission and communication. Modular plug connections are also used in the industrial sector. Standardized assembly units are available for machines and systems, into which a wide variety of plug connections can be integrated. This allows individually multifunctional plugs and sockets to be put together. Use compact plug connections in terminal boxes and control cabinets.

What types of modular connectors are there?

There are many different types of modular connectors. The world's best known and most widely used modular connectors are:

  • RJ10 - (4 positions and 4 contacts) - connects a telephone handset to a receiver
  • RJ11 - (6 positions and either 2 or 4 contacts) - is used to connect telephone lines and modems, with 4 contacts with power supply via the second pair
  • RJ12 - (6 position and 6 contacts) - for telephone line and additional control lines, used in larger telephone systems
  • RJ13 - (6 position and 4 contacts, with a circuit behind the line) - for telephone line and additional control lines
  • RJ14 - (6 positions and either 4 or 6 contacts) - is used to connect two telephone lines, with 6 contacts with power on the third pair
  • RJ45 - (8 positions and either 8 or 10 contacts) - Connector for high-speed data transmission in computer networks

 

What special properties do modular connectors have?

Special requirements must be met when modular connectors are used in factories, in automated processes or in image processing systems. Many of the modular connectors therefore have additional features. This makes them usable for specific applications. For example:

shielding

  • If electromagnetic interference is to be expected or the lines are very long, shielded lines and plug connections are often used. These cancel out electromagnetic interference.

 

keying

  • Due to an attached tab, insertion of a true RJ45 plug into a jack is only possible in one orientation. This is to avoid improper wiring. Standard 8P8C connectors do not have this security feature.

 

Assembly

  • For production use, panel mount, board mount, through-hole mount, and surface mount are often possible. The sockets can have a vertical or horizontal orientation.

 

display functions

  • Modern modular connectors may also contain LEDs of different colors to indicate connection status.

 

magnetics

  • Magnets must be taken into account with any Ethernet connection. These are part of the Ethernet specification for 10BASE-T and 100BASE-T networks. The integration of the magnetics in the RJ45 socket shields against electromagnetic interference. Data connections are becoming more reliable.

 

Highest quality

Modular connectors are used in systems where high reliability and performance are important. These are, for example, the military and aviation and space travel.


In order to meet the highest requirements, high-performance shielding, special coding, protective sleeves and particularly robust parts are used in these so-called Hi-Rel (High Reliability) models.
