Specifications

Part-Number Decode & Cross-Reference

Applications

• Bulkhead pass-throughs where no mounting flange may protrude into the enclosure
• Jam Nut Receptacle for a 4-way #12 harness run (insert 14-4)
• Ground-support, test-bench and vehicle wiring where the bayonet interface is already qualified
• Series II rear-release crimp repairs on legacy MIL-C-26482 harnesses
• Keyed mating pairs where position W prevents cross-plugging of adjacent connectors

The MS3474W14-4PW is a 4-contact (pin) jam nut receptacle in the MIL-DTL-26482 Series II family, shell size 14, insert arrangement 14-4. A jam-nut body with a single bulkhead nut, mounted through a panel from the rear so no mounting flange protrudes into the enclosure. Series II keeps the three-point bayonet interface of the original 26482 but replaces solder cups with rear-release crimp contacts, so contacts are terminated and inspected on the bench before insertion. The cadmium olive drab finish suits corrosion-led outdoor and engine-bay exposure. This variant carries alternate key position W, which rotates the insert so it will only mate with a receptacle keyed to the same position — the standard way to keep two adjacent connectors from being cross-plugged.
