Connection box - copper

In the field of data communications technology, you will find a wide range of junction boxes at eibabo®. In this catalog we offer you devices for signal transmission with copper cables. Here you can read interesting facts about the use of the well-known RJ plug connections and their origin. These proven junction boxes for data technology offer you maximum flexibility, reliability and ease of installation.

We carry modular and compact junction boxes in different performance classes for:

  • flush mounting
  • surface mounting
  • Mounting on the DIN rail or for duct installation

 

In connection sockets, a distinction is usually made between single sockets and double sockets. In addition to the variants for copper cables, you will find connection sockets for fiber optic cables in other categories of our shop. Matching keystone modules are also available for almost every connection. Our range includes products of the highest quality, which also meet high demands or industrial use.

Junction boxes with connector types from the RJ series

RJ plug connections are mainly used to create network connections. The 'Registered Jack' connectors are standardized network interfaces with a defined design for plugs, sockets and their circuits. These are used to connect telecommunication devices. The most well-known standards include RJ-11, RJ-12, RJ-45 and others. The contacts inside are in the form of blades which, when crimped with a special tool, cut through the conductor's insulation and create a conductive connection. The connectors are usually made of transparent plastic so that the assignment of the contacts can be seen.

The crimping

You can obtain special crimping tools for assembling connectors from the RJ series here in the shop. There are universal crimping tools that you can use to crimp all types of RJ plugs. There are also crimping tools that are only suitable for certain connector types.


The Registered Jack Standard was originally developed and patented by Bell Laboratories in 1975. This should standardize the connectors used and simplify the work of connecting end devices. Thanks to the support of the US Federal Communications Agency, these were quickly established as the standard for connecting subscribers to telephone networks.

Which RJ connectors are the most common?

In order to better understand the designation of the plugs and sockets, you should know their structure. The plugs and sockets have a specific number of contact positions. Depending on the model, this can be four, six, eight or ten pieces. However, a contact does not have to be installed at every contact position. This results in the plug designation or the socket designation. Some examples:

  • A 4P4C connector has four contact positions, all four of which are occupied by contacts.
  • A 6P2C connector has six contact positions, only two of which are occupied by contacts.
  • An 8P8C connector has eight contact positions, all eight of which are occupied by contacts.

 

The RJ-9 connector (4P4C) is mainly used to connect telephone handsets to telephone sets. These are the smallest connectors in the RJ series. These have four contact positions and four contacts.

RJ-11 connectors are used to connect the phone cords from landline phones. There are two types of RJ-11 connectors: two-pin as 6P2C and four-pin as 6P4C.

RJ-12 connectors are similar to RJ-25 connections. These have six positions and six contacts (6P6C) and are primarily used to connect proprietary telephones with a six pin connector.

The RJ-45 connectors are very common. These have eight occupied contact positions (8P8C) and are designed for the connection of telecommunication devices. You will find them on computers, network connection sockets, network switches or patch panels. Depending on the cable used, these plugs differ in the shape of the cutting blades:

  • Blades for single core twisted pair cables where the conductors consist of only one solid conductive core
  • Blades for multi-core twisted pair cables, where the conductors consist of several conductors (strands) braided together
  • Triple blades for both types of twisted pair cables

 

Externally, the RJ-45 connectors for different cables do not differ. The difference lies in the position of the contact blades that cut through the cable insulation. Shielded RJ-45 connectors are used with a shielded twisted pair FTP cable for protection against interference and radio interference. You will receive suitable junction boxes for this, which also offer shielding.

 


TIP:

There are rubber caps with different color markings for some RJ plugs. These enable better assignment and prevent kinking and damage to the cable at the connector input.


 

10P10C plugs and sockets are referred to as RJ-50. These have ten occupied contact positions and are used to control uninterruptible power supplies, barcode scanners and medical devices.

What are keystone junction boxes?

Keystone is a modular insert for passive network devices such as junction boxes or patch panels. These inserts fulfill the function of ports to which, among other things, RJ plugs can be connected. You will receive Keystone junction boxes, which form the framework for using your Keystone modules. All Keystone modules have a set shape and two sides for connecting wires and/or connectors. Depending on the type of connections, the models are divided into 3 types:

  • Unchangeable – there are identical connectors on both sides
  • Variable – with different connections
  • Socket – the most common, on the front side there is a socket for inserting a plug (for example RJ-45), and on the back side there is a connector with insulation displacement terminals for fastening an uncrimped cable.

 

What does the specification of the category mean for a junction box?

If you want to buy a junction box and look at the characteristics of the devices, you often come across the indication of a category. This information is an indication of the possible speed of data transmission. Just like the connection sockets, your network cables are also classified into different categories.

  • The CAT-5 standard offers a transmission speed of up to 100 Mbit/s.
  • The CAT-5e standard offers ten times faster speeds of up to 1000 Mbit/s or 1 Gbit/s.
  • Networks based on the CAT-6 standard and associated hardware support 10 Gbit/s. The specification 6A designates the further development of this standard with an increased transmission frequency.

 

Please match the rating of the junction box to the rating of your connection and the type of cable you are running.
