MS3116F

MS3116F is the start of a military part number for a circular connector under MIL-DTL-26482 Series 1. The MS3116 detail sheet covers straight plugs with solder contacts and bayonet coupling; the letter F is the class, an environment-resisting plug with a strain-relief cable clamp at the rear. The full part number then adds shell size (8 to 24), insert arrangement, contact style (P = pins, S = sockets), an optional alternate insert position (W, X, Y, Z) and a finish code, for example MS3116F12-3PW.

MS3116 plugs mate with the MS3110, MS3112, MS3113, MS3114 and MS3119 receptacles, and the insert layouts are defined in MIL-STD-1669. Many makers build them (for example Amphenol, Souriau and ITT Cannon). The MS3116 sheet has been inactive for new design since 15 December 1998 and is kept for replacement use.

The item in our photo is a cable assembly: a bayonet plug of this style with a saddle-clamp strain relief, marked as made in France, on a black multi-core cable with a small connector at the other end. The full shell size and insert code are not readable in the photo.
