The 851 connectors feature a positive bayonet coupling mechanism, ensuring reliable mechanical and electrical connection between two mating halves. A helical locking ring on the plug couples with three dowel pegs on the receptacle ensuring rapid locking. Orientation and location is ensured by a system of five raised keys on the plugs which couple with corresponding slots on the receptacles.
