MIL-DTL-38999, or D38999, connectors are the latest generation of circular military connectors. They are popular due to their compact size, high contact density, vibration resistance, quick coupling and environmental performance.
They come in four series:
Series I – (MS2746) – bayonet coupling – scoop proof
Series II – (MS2747) – bayonet coupling – low profile
Series III – (D38999/2) – threaded coupling – scoop proof
Series IV – (D38999/4) – Breech-lok (push-pull) – scoop proof
