The MIL-DTL-38999 Series II connectors are bayonet coupling subminiature configuration with a low profile design using a shorter socket contact than used by Series I and III. This series is used for instrumentation applications where space is at a premium. Series II is not scoop proof. Series II is available in nine shell sizes with five receptacle configurations and standard or RFI plugs. 54 insert arrangements using 3 to 128 contacts terminating wire gauge sizes 28 through 12. The hard plastic socket interface features the chamfered conical entry that aids in proper contact mating.
