Registered Jack telecom connectors

Most telecom connectors are standardised so that it is easy to find connectors that work with any telephony system. The most common type of connector is the Registered Jack, which has a rectangular end that clips into place when inserted into the socket.


There are, however, a few variations within RJ telecom connectors. The RJ11 connectors are the most common type used for home phones, RJ12 connectors are typically used in system phones, and RJ14 connections are used in systems with two telephone lines.
