Description :

The 851 serie connectors feature a positive bayonet coupling mechanism which ensures reliable mechanical and electrical connection between mating halves. The plug features a helical locking ring which couples with the three dowel pegs on the receptacle ensuring rapid locking. Orientation and location is achieved with a system of five raised keys on the plugs which couple with corresponding slots on the receptacles. Connectors with different angular positioning of the insulator relative to the shell can be provided to prevent undesired accidental mating of adjacent connectors with the same contact arrangements.
