MIL-DTL-5015 Series II is the successor generation of the classic MIL-DTL-5015 threaded-coupling circular connector, and is the standard choice for heavy-duty power and control circuits on machinery, vehicles and ground-support equipment. Shells couple with a threaded ring rather than a bayonet, so they resist vibration and are slower to disconnect — deliberate for circuits that must not open accidentally. Contact sizes run from #16 at 13 A through #12 at 23 A and #8 at 46 A to #4 at 80 A, so one shell can carry a mix of control and power circuits. Series II carries crimp contacts for field-repairable harnesses, while Series III uses solder cups; both share the shell threads and insert arrangements, so a Series II plug mates a Series III receptacle. Airoadcon supplies contacts and, on request, a kit with the mating half and a backshell.
