RJ-11


RJ11 é um conector usado geralmente na terminação de fios de telefone. Quase sempre é do tipo 6P4C, com quatro presentes, sendo somente dois utilizados. O conector com seis vias (entradas) presentes é pouco utilizado mas se encontra em equipamentos como gavetas de valores e outros equipamentos ligados ao computador. No Brasil, o RJ-11 está substituindo a Tomada Telebrás nas conexões telefónicas.
O padrão de conexão RJ-11 especifica não só os aspectos físicos do conector elétrico, mas também a pinagem, isto é, a função de cada contato do plugue.[1] Conectores modulares são especificados para a série de conectores registered jack (RJ), bem como para os conectores modulares Ethernet e outros conectores, como o 4P4C (4 posições, 4 contatos), o padrão de facto para cordões de handset,[2][3][4] ao qual refere-se como conectores RJ.

The abbreviation for registered jack, RJ defines a particular wiring scheme of individual wires into outlet contacts. For example, a 6-position outlet may be wired to RJ-11C scheme (one pair), RJ-14C (two pairs), or RJ-25C (three pairs).

This 8-pin modular plug is probably the most subject to name abuse, because it resembles the specialized RJ-45 connector. However, the RJ-45 wiring pattern (which includes an interface programming resistor) is so radically different from that of T568A and B that it really should not be called by that name at all.

The RJ (registered jack) prefix is one of the most widely (and incorrectly) used prefixes in the computer industry; nearly everyone, including people working for cabling companies, is guilty of referring to an eight-position modular jack (sometimes called an 8P8C) as an RJ-45
