The M28840/12BG1P4 is a MIL-DTL-28840 connector — the U.S. Navy shipboard circular standard — configured as a box mount receptacle in shell size G, insert arrangement 1, service class B, with pin contacts and key position 4. The family is built for high-density, high-shock duty: a splined backshell interface, front-release crimped contacts and an integrated wire-sealing grommet let a harness be built and repaired in the field without potting. Threaded coupling with a keyed shell prevents mis-mating in low-visibility compartments. Like all M28840 and M85049 QPL items, the part number is identical across every qualified source, so Airoadcon, Amphenol, Glenair and TE parts interchange without a specification change.
