MIL-C-38999 Series II

The MIL-C-38999 Series II connector series is a bayonet coupling sub miniature configuration, with a lower profile design, accomplished by utilising a shorter socket contact than employed in series I and III. As a result, the connectors are not a 100% "scoop proof". This series is popular for instrumentation applications where space is at a premium. The connectors are available in nine shell sizes with five receptacle configurations and standard RFI plugs. There are 54 insert arrangements available, utilising 3 to 128 contacts. Contacts are 22D, 20, 16 and 12 gauge (and combinations), terminating wire sizes 28 through 12 gauge. The hard plastic socket interface features the chamfered conical entry that aids in the proper mating of contacts. The fluorosilicone interfacial seal has conical risers around each pin contact that compress into the socket interface, assuring the seal of the mating surface. Cadmium over Nickel, Anodic and electro less nickel finishes are available for aluminium shells. Polarisation is machined into the shell (Locksmith Keying).
