The Molex 5023801200 is a 12-circuit plug housing from the CLIK-Mate 502380 series, designed for wire-to-board interconnects at 1.25 mm pitch. It is a free-hanging (in-line) housing that accepts crimp terminals — the contacts are ordered separately and are not included with this part. The single-row layout and latch-lock fastening make it suited for harness assemblies where a positive retention click is needed against vibration or cable tug.
What It Mates With
This plug housing mates with the matching CLIK-Mate 502380 series receptacle header (board-mount, through-hole or SMT). The 1.25 mm pitch and latch-lock keying ensure the plug only seats in one orientation — you should hear it click when the lock engages. Because the contacts are crimped separately and inserted into the housing, the wire gauge and terminal part number must be confirmed against the receptacle's contact spec before ordering.
