MIL-DTL-38999 Series I J991F
MIL-DTL-38999 Series I is a bayonet coupling sub-miniature connector design offering high contact density ideal for small wire gauge signal pin applications. This series is environment resisting and the mating is “scoop-proof.” Pins are recessed in elongated shells to prevent the possibility of bending contacts when plugs are scooped across the mating receptacles. CarlisleIT offers three standard shell styles of receptacle, the front wall mount, the rear box mount and the jam nut. Please see the Conesys/Aero-Electric catalog, Military Specified Circular Connectors, for non-filtered plug mates. The Series I connectors offer over 50 insert arrangements, from MIL-STD-1560, to choose from. Contact sizes include 22D, 20, 16, 12, 10 and 8. CarlisleIT customers can use the sizes 12, 10, or 8 for power based on load requirements. Shells are aluminum base material with electroless nickel or olive drab cadmium, standard. Consult the factory as CarlisleIT can provide other finishes as well as passivated stainless steel when necessary. The Series I offer closed entry socket inserts raised moisture barriers around each pin for full environment resisting capability.
