Procurement Notes
Verify the specific suffix M1R against official Harwin documentation to confirm it denotes the correct reel packaging and variant. Ensure compatibility with automated SMT placement equipment. Confirm RoHS compliance status via the latest datasheet before procurement.
Selection Notes
Select this component when a vertical surface mount header with 34 positions is required. The 1.25 mm pitch allows for high density. The Screw-Lok feature provides mechanical stability superior to standard latches in vibration environments. Verify PCB thickness requirements for mounting.
Part Context
Part of the Harwin Gecko-SL family, known for reliability in extreme conditions (-65°C/+150°C). The series offers various mounting styles including through-hole and surface mount options with different locking mechanisms like Jackscrew or Latch.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Cross-reference with other 1.25mm pitch SMT headers only if form-fit-function matches are verified by engineering.
FAQ
What type of fixing mechanism does this connector use?
It is fitted with internally threaded Screw-Lok fixings for secure board mounting.
