Ethernet connector

A telephone connector that holds up to eight wires. RJ-45 plugs and sockets are used in Ethernet and Token Ring Type 3 devices.

A 8-contact connector type most often used for unshielded twisted pair LAN wiring between a computer and LAN wall outlet connector. Devices that use this connector are not necessarily intended for electrical connection to a LAN. Some RJ45 connector cables have 10 pins.
