MS3474W18-32SN is a jam nut receptacle in the MIL-DTL-26482 Series II (Matrix 2) family, shell size 18 with the 18-32 insert arrangement — thirty-two size 20 socket contacts at 7.5 A each — in the class W olive drab cadmium finish. The single-hole jam nut mounting lets it sit tight against a panel or casting instead of requiring the four-hole flange of the MS3470 wall-mount body.

The trailing N is the insert rotation code: an N-key part is the standard, unrotated insert and mates with an N-key plug of the same shell size and arrangement. Series II receptacles carry the socket (female) contacts while the mating straight plug (MS3475 or MS3476) carries the pins, which keeps the more easily damaged contacts in the replaceable cable half of the pair.
