Souriau 851 circular connectors were originally conceived to ensure reliable electrical connections in aircraft, but their lightweight, compact design 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, etc).
The connectors conform to the following international standards: MIL-DTL-26482G series 1, NFC 93422, HE 301B, VG 95328, GAM/T1 list. They 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 to ensure 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. Connectors with different angular positioning of the insulator relative to the shell can be provided to prevent mating of adjacent connectors with the same contact arrangements.
The connector shells are manufactured from aluminium alloy. The insulators are moulded from elastomer and are bonded into the shells. Grommets are also made from elastomer and are supplied with appropriate accessories in the solder version, but are integral with the insulator for the crimp version. Copper alloy contacts have gold or tin over nickel plating.
Hermetic receptacles with gold plated solder contacts are made from steel shells with nickel plating (01H) or yellow cadmium plating (02H and 07H). The contacts are permanently fused into a glass insulator, providing a high level of sealing. To facilitate cabling, solder and straight spill contacts size 20 are offered (including hermetic versions) with a gold plated active part and tin plated terminations.
