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 elec-
trical 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. 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 acces-
sories 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 we offer solder and straight spill contacts size 20 (including hermetic versions) with a gold
plated active part and tin plated terminations.
