Souriau 851 circular connectors were originally conceived to ensure reliable electrical connections in aircraft but their lightweight compact size and general characteristics have contributed to successful adoption in numerous civil and military aviation applications and also in the fields of professional and general electronics (machine tools, automation, measuring equipment…). 851 connectors conform to the following international standards, MIL-DTL-26482G series 1, NFC 93422, HE 301B, VG 95328, GAM/T1 list. 851 connectors feature a positive bayonet coupling mechanism which ensures reliable mechanical and electrical connection between 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.
