These low pass filter connectors include the most popular circuits, C, CL/LC, Pi and T, and are constructed using planar filter technology for maximum strength and high performance from low to high frequencies.

MIL-DTL-38999 Series I

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. The Series I offers closed entry socket inserts and raised moisture barriers around each pin for full environment resisting capability.

MIL-DTL-38999 Series II

Featuring the bayonet coupling system with a low profile design, the Series II are perfect where the external shell should be lower and lighter weight. This series offers the closed-entry socket inserts and raised moisture barriers around each pin contact and all the shell key/keyway positions found in the military specification.

MIL-DTL-38999 Series III

MIL-DTL-38999 Series III is the cylindrical connector designed for highest performance in general purpose and severe environment applications. These connectors feature an improved ‘one-turn’ coupling system, utilizing a selflocking acme thread. Blunting the threads of both plug and receptacle eliminates cross threading. This family offers scoop-proof design, closed entry socket inserts and raised moisture barriers on the pin interfacial seals.

MIL-DTL-38999 Series IV

The MIL-DTL-38999 Series IV quarter turn mate and release are designed with rack, panel, and warfighter applications in mind. Reliablity is high due to the scoop-proof design and the shell grounding prior to engagement of contacts. The Series IV performs very well in settings where vibration and shock are critical. The nature of the mechanics of the quick lock coupling also offers good EMI performance, further enhanced with our internal low band pass filter.
