Board locks and a mounting flange provide mechanical retention through wave solder and against cable strain in a vibration environment — a practical detail for an automotive or industrial enclosure where the connector sees mechanical shock. ## Mounting and footprint This is a board-edge, through-hole, right-angle header. The 3.70 mm pitch and 3.60 mm row spacing define the PCB footprint — the hole pattern and keep-out zone must match the 4-row layout. The blue nylon (PA) insulator stands 0.980\" (24.90 mm) above the board, so check the enclosure height clearance against the mated receptacle stack. The mounting flange adds a screw-down option for extra shear resistance in high-vibration assemblies — a detail worth noting if the cable bundle exerts leverage on the connector body.","metaTitle":"Molex CMC 0643340500 Header, 32 Pos, 3.70 mm, 12 A","metaDescription":"Molex 0643340500 CMC series header, 32 circuits, 3.70 mm pitch, 4 rows, right-angle, board-lock, rated 12 A.
