Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific pin count and pitch against official Harwin datasheets to ensure compatibility with mating receptacles. Confirm that the gold plating specification matches the application requirements for low-contact resistance. Check regulatory compliance status, as some variants may not be RoHS compliant. Ensure the jack screw locking mechanism fits within the available enclosure space constraints.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a secure, locked connection is required for board-to-board or cable-to-board interfaces. The straight orientation suits applications where vertical clearance is limited but horizontal space allows for jack screw operation. Consider the beryllium copper material properties for durability in high-vibration environments. Verify thermal ratings if operating near maximum temperature limits.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Harwin M80 series, known for robust mechanical design and high-density connectivity options. The series supports various configurations including mixed contacts and different terminal styles.
