MIL-DTL-28840 is the U.S. Navy shipboard circular series: high-density, high-shock, threaded coupling with front-release crimped contacts and an integrated wire-sealing grommet. The part number carries no brand — like M85049 it is a QPL standard, so the same M28840/18AG1S2 is built by every qualified source. Key position 2 prevents a key-1 shell from mating into the same panel.
