There are guides in the socket for the precise insertion of the plug with its bars. The socket contacts are spring-loaded and covered with a thin gold layer. The data cables are connected using insulation displacement technology and a special tool.

As with the RJ45 plug, the connections are numbered in pairs. The RJ45 sockets are available in shielded and unshielded versions; in the case of the shielded version, care must be taken to ensure sufficient contact between the shielding and the shielding of the plug in order to achieve the lowest possible shielding resistance. Unshielded sockets are mainly used in the telephone sector, as the transmission parameters are sufficient for these applications.
