The RS series connectors are cylindrical low-frequency connectors, designed to work in electrical circuits of direct, alternate (up to 3 MHz) and pulse currents. The RS connectors are designed for indoor installation. The RS connectors consist of a hermetically sealed or non-sealed panel-mounted plug and a non-sealed panel-mounted or cable-mounted socket. The coupling between the RSGATV, RSGTV, RSATV, RSTV plugs with RSBATV, RSBTV sockets is threaded. The coupling between the RSGBATV, RSGBTV, RSBATV, RSBTV plugs with RSBATV and RSBTV sockets is cut-in. The polarization of the shells is single-key. The RS connectors are made without a casing or with a metal or plastic casing. Contact plating: RSGATV, RSGBATV, RSBATV, RSATV — gold; RSGTV, RSGBTV, RSBTV, RSTV — silver.
