RJ is the connector used in telephone wiring. RJ is the short form for Registered Jack and it is a physical connector interface used in telephone wire terminals. There are many design standards for registered jacks and these include RJ11, RJ14, RJ45 and so on.
An RJ11 Jack has a total number of six connector positions, but out of the many positions only two or four are utilized. The RJ connector comes in two forms one which is the flat satin form and the other, which is the unshielded twisted pair form. It is the most common of registered jacks and is used mostly in homes and offices across North America. Since an RJ11 jack uses two out of six positions, it can be wired with a 6P2C modular jack variety. However, you should note that such jacks are rarely used.
In addition to being used in telephone wire terminals, RJ11 connectors are also used in selective ringers, anti tinkle circuitry and in selective ringers. The powered version of RJ11 connectors, low voltage is carried by pins 2 and pin 5. The power to these pins comes from a transformer that is plugged into the wall. Four-wire cables with 6P4C plugs are used to insert telephone terminals into RJ11 jacks.
Most often, there is a comparison made between RJ11 and the RJ45 jack. RJ11 is used for the purpose of connecting telephone systems, but RJ45 is used for connecting system in a network. RJ45 jack is bigger and it can accommodate more wires that RJ11.
The RJ11 is the most common type of registered today and it is used for the purpose of terminating phone lines. They are usually used with single line POTS (Plain Old Telephone Service) handset jacks. When using an RJ11 conductor, make sure to follow all instructions so that your connection with any device is done correctly.
