The RJ45 connector, short for "Registered Jack type 45", is one of the most widely used standards for Ethernet network connections. Featuring the 8P8C configuration (eight positions and eight contacts), it is designed to terminate twisted pair cables, such as Cat5e and Cat6 cables, ensuring high-speed data transmission between devices such as computers, routers, and switches. RJ45 connectors are available in both shielded and unshielded versions. Shielded versions offer additional protection against electromagnetic interference (EMI), making them ideal for environments with high electronic noise. The pinout follows the T568A and T568B standards, which define the wiring order, ensuring compatibility and optimal performance in networks. Thanks to their reliability and efficiency in data transmission, RJ45 connectors are widely used in both domestic and industrial applications, providing fast and stable connections.
