The M83723/84A1212N is a threaded jam nut receptacle from the MIL-DTL-83723 Series III family. The /84 style mounts through a single D-hole in the panel and locks with a jam nut, with an integrated silicone O-ring sealing the mounting hole for environmental installations. This variant carries 12 female sockets at contact size #20 on the 12-12 insert, and the A class is a black non-conductive anodized finish — chosen where a conductive, corrosive-protective coating is not wanted or where cadmium is prohibited. Series III is scoop-proof and shares the MIL-STD-1560 insert arrangements with EN2997 and the ESC10/ESC11 family, so the same panel cut-out accepts all three.
