D38999 Series I, II, III, and IV: The World's Most Complete Selection of QPL and COTS 38999 Interconnects PLUS a full range of other MS Standard Circular Connectors Including M28840, M26482, AS81703, and More

Multi-pin MIL-DTL-38999 Series III circular connectors with size #22 crimp removable contacts have been a standard in both military and commercial aviation since the 1970s. MIL-C-38999 connectors were first developed for the interconnection of communications and avionics equipment in harsh Navy and Air Force airframe applications, particularly those subject to high-vibration, wind, and moisture. Today, a broad range of D38999 type cylindrical connectors — specialized for land, sea, air and space applications — are used for the interconnection of electronic systems, sensors, power supplies and other equipment that depend on reliable performance and standards-body guarantees for performance and quality.

From satellites to ruggedized shipboard and industrial applications, Glenair supplies literally every power, signal, high-speed, EMI/RFI filter, RF, and printed circuit board cylindrical connector configuration. From our QPL'd MIL-DTL-38999 hermetic, environmental class, and G class Space-Grade Series I, II, III, and IV solutions to our parallel “Better than QPL” SuperNine Series, Glenair leads the industry in the design and development of high-performance, made-in-America, mission-critical military/aerospace connectors.
