Applications

The D38999/24WE2SN is a jam nut receptacle from MIL-DTL-38999 Series III: it mounts to a panel through a single threaded hole and locks with a nut, which gives a compact rear footprint where a square-flange wall mount will not fit. The E-2 insert in shell size 17 carries 39 positions — 38 signal contacts plus one twinax pair for high-speed or screened signal runs. The W finish is olive drab cadmium over aluminium, the standard military plating; mated with a D38999/26WE2 plug the assembly is environmentally sealed.
