MIL-DTL-38999 Series IV uses a Breech-Lok 90° quarter-turn coupling that is scoop-proof and suited to blind-mate rack-and-panel installations. It shares the insert arrangements and contact system of Series III, so contacts and tooling are common across both series, while the coupling mechanism gives a shorter, more positive engagement than the Series III triple-start thread. Airoadcon supplies M39029-class crimp contacts and, on request, a kit with the mating half and a backshell.
