The 2132271210: This Molex CLIK-Mate 213227 receptacle lands on a 1.50 mm pitch, dual-row layout, carrying 12 circuits fully loaded. That 0.059" centerline is the first thing to verify against your PCB footprint — it dictates the pad spacing and the mating header pin pattern. The 12 positions are all loaded, so every contact is present. No dummy cavities to account for in the harness count.
Contact finish – what the gold flash buys you
Mating side carries gold flash at 0.100 µm (3.94 µ") over copper alloy. That's a thin layer — enough to prevent oxidation during storage and through a few dozen mating cycles.
Fastening type is a latch holder — a positive lock that clicks when the plug is fully seated. Unlike a friction-only fit, this latch resists back-out from cable tug or equipment vibration. The housing is UL94 V-0 nylon, standard for any product that needs a flame-rated enclosure.
