The M39029/28-211 is a size 12 shielded coaxial pin contact that carries a single coax channel through a standard MIL-DTL-38999 cavity. It crimps both the centre conductor and the outer shield, giving 360-degree shielding continuity from cable braid to connector shell — the property that makes it usable on RF feeds, data buses and MIL-STD-1760 aircraft-store interfaces where a plain signal contact would leak. It fits MIL-DTL-38999 Series I, II, III and IV connectors, so it can be specified across an entire platform rather than per connector generation. Typical use is 1553-style buses, video and RF payload links, and any circuit where the harness is routed alongside power wiring.
