MC-Sockets BP...AR-N are sockets with snap-in locks and they lock automatically when connected.
Plugs S...AR-N or SP...AR-N are inserted only so far that the ring snaps-in.
To release, lightly turn and push-in plug, then pull-out.
BP...AR-N sockets have a crimp connection suitable for flexible and highly flexible Cu-cable.
Multi-Contact recommends an hexagonal crimp.
Indent crimping is also possible. Cables with compacted conductors need a special crimping sleeve.
Insulating sleeves and cable insulators are also available for these sockets.
