Bridge plug
The LEMO audio-video connector system consists of two sockets, with or without microswitch, a bridge plug with or without
output monitoring and a plug with or without bend relief. This system is already widely used in telecommunication equipment
and in radio and television broadcasting centres.
The connectors of this system are fully compatible with all other connector models of the same series and type. However,
when designing systems it should be considered that the distance between the assembled nut-fixing models should correspond
to that between the outputs of the bridge plug. In order to provide the user with a coding system, the bridge plug housing,
the double panel washers and the bend reliefs are available in nine colours.
