11/21/2023 0 Comments Phone jack rj11RJ12 connectors can be used in place of RJ11 because RJ12 has all the connectors RJ11 needs (plus 4 extra). They are used to connect a phone line with the key telephone system, small exchange-like systems used by businesses to connect to the carrier on the outside and create a network of phones and extensions on the inside. RJ12 connectors are also similar to RJ11 but have a 6P6C configuration. It is not an official ACTA (Administrative Council for Terminal Attachments) specification. It has a 4P4C configuration and is used in handset cords. RJ22, also called an RJ10, is the smallest of the modular plugs. RJ61 is a similar registered jack for 4 lines it uses an 8P8C configuration similar to the RJ45. RJ25 uses all 6 of the available positions (6P6C) and is able to connect 3 lines. RJ14 is similar to RJ11 but is wired for two phone lines it uses a 6P4C configuration where 4 connectors out of the 6 positions are used. AmerTac manufacturing brands offer complete. The RJ11 technically uses the center 2 contacts of 6 available, and is used for wiring a single phone line. The Zenith Surface Mount RJ11 Jack with White finish allows you to easily add a modular 4 conductor phone jack. These are all modular connectors with 6 available positions. All three jack types are used to connect phones-for one-, two-, and three-line service respectively. Product: RJ11 Telephone Jack with Shutter Product Category: Switches & Automation Size: 1 Module Material: Polycarbonate. RJ11 is the most widely-used connector, followed by RJ14, and RJ25. This includes phone lines and ADSL connections. With only 2 of the 6 available connection points, the RJ11 plug supports limited-bandwidth applications. RJ11 is used for connecting single phone lines and uses a 6P2C or 6P4C configuration. RJ45 is also sometimes used for VOIP phones in offices. Overall bandwidth is, of course, contingent upon what other components of the network such as cabling or routers can support. Using 8 contacts allows for greater bandwidth so RJ45 is used for data-intensive applications like Ethernet and can support bandwidth up to 10Gbps.
