RJ11, RJ12 & RJ22 Plugs

RJ11, RJ12, and RJ22 connectors are implemented within nearly every telephone and data network installation. The prefix "RJ" refers to registered jack, and is the standardized hardware interface for telecommunication equipment. RJ11 tends to be the most common type of modular plug out of the three found, here; this modular plug along with other modular plugs alike, are designed to effectively carry voice or analog signals for telephone communications. Also, Primus Cable supplies RJ11 (6 position, 4 contact) connectors, RJ12 (6 position, 6 contact) connectors, and RJ22 (4 position, 4 contact) connectors for telephone and data applications.

The RJ11 Modular Plug for Round and Stranded Wires is ever popular for installers. This modular plug comes in various quantities to fit the specifications of your application, once you have decided upon the best option. You may want to note that RJ11 and RJ12 connectors appear very similar, only the RJ12 uses all six positions, while the RJ11 uses only four. RJ12 connectors can utilize more lines than an RJ11. RJ22 plugs have only four pins, and tend to be used just for handsets to telephone connections.
