Product details

Rated at 12 A per circuit at 14 VDC, this header is sized for moderate-current duty — think power distribution within an automotive ECU, an industrial controller backplane, or a battery-management interconnect where the 12 A per pin handles the main rail without needing a separate busbar. 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.

Frequently asked questions

What is the mating connector for 0643340500?

The 0643340500 is a male pin header that mates with the matching CMC 64334 series receptacle housing and crimp terminals. The mating half is a female connector with the same 3.70 mm pitch and 4-row configuration.

Does Molex 0643340500 have a board lock?

Yes, the 0643340500 includes board locks and a mounting flange for mechanical retention during soldering and in-service vibration.
