RJ Jacks

RJ (Registered Jack) jacks and plugs are standardized connectors used in telecommunications for connecting voice and data equipment. Commonly associated with Ethernet networking, RJ jacks and plugs feature a modular design with a specified number of positions and contacts. The most prevalent types are RJ45, employed for Ethernet connections, and RJ11, utilized in telephone applications. These connectors follow a color-coded wiring scheme, ensuring consistent pin assignments. RJ plugs have gold-plated contacts for reliable conductivity, and the jacks often incorporate a keystone design for easy installation in wall plates. The RJ standard streamlines connectivity, promoting compatibility and interchangeability in diverse communication systems.
