The Molex 5018203231 is the 32-circuit member of the CMC 501820 series — a 4-row shrouded header intended for board-to-cable panel-mount applications. Push-pull fastening mates and releases without hardware; the full 4-wall shroud protects the pin array during handling and in high-vibration environments. All 32 positions are populated with rectangular male pins, tin-plated on both the mating face and the solder tail.
Ratings that drive selection
Rated 12A per circuit at 14VDC — this is a power-duty header, not a signal-density part. The tin-tin contact finish is adequate for the cycle life typical of field-service panel connections but falls short of gold's make-break durability. The PBT-GF housing carries a thermal ceiling implicit in the voltage rating; check the derating curve against your local current if the header sits near a heat source.
Fit and mating
Panel-mount solder termination — the board footprint is driven by the 4-row x 32-position array and the panel-opening cutout the shroud requires. Confirm the panel thickness range your application can accommodate before committing. The matching receptacle housing (not listed here) is the mandatory mating half — the push-pull latch holds the pair seated without jack screws, so verify the latch retention force meets your vibration requirement.
