This is the socket half, designed to be crimped onto a wire and inserted into a Multimate III+ housing cavity.
Crimps onto 14-18 AWG stranded wire — a common range for power and signal circuits in industrial and automotive harnesses.
Gold plating — what it buys you
It resists oxidation through multiple insertions and holds stable contact resistance across temperature swings. For a crimp socket that may be field-serviced or swapped, this plating grade is the difference between a reliable re-mate and a high-resistance joint after a few cycles.
