Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against official Harwin documentation to confirm contact plating type and mating height requirements. Ensure compatibility with existing PCB footprint designs, particularly regarding the recommended 2.54 mm pitch pattern and hole diameter specifications. Confirm that the right-angle form factor aligns with mechanical clearance constraints in the final assembly design.

Headers, Male Pins Selection Notes

Select this model when high pin density is required in a limited vertical space due to its right-angle configuration. The 64-position count supports complex signal routing needs. Verify that the 3 A current rating and 750 V voltage withstand capability meet the specific circuit requirements. Consider the through-hole mounting method for robust mechanical fixation during operation.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, a widely used line of connectors known for reliability in industrial and commercial electronics. The M20 series offers various configurations including straight and right-angle headers with different contact plating options.
