Applications

The M83723/75W12127 is a MIL-DTL-83723 Series III straight plug carrying twelve size-20 socket contacts in a shell 12 envelope, arrangement 12-12. In the 83723 numbering the slash sheet sets the shell type — /75 is the straight plug with socket contacts, /76 the pin version — and the arrangement number equals the contact count directly. Series III is the scoop-proof generation of the family: the bayonet coupling engages before the contacts align, so a mis-aligned mating attempt cannot bend pins, which is why it replaced Series I on new airframe and ground-vehicle harnesses. Class W cadmium olive drab over electroless nickel gives conductive corrosion protection, and the 83723 envelope holds up to 200°C for engine-adjacent and avionics-bay installations. Contacts are M39029 crimp, front release / rear removable.
