Procurement Notes
Verify the specific ordering suffixes and packaging options directly with the manufacturer or authorized distributors. Ensure that the selected variant matches the required right-angle orientation and contact plating specifications for your application. Confirm availability of tape-and-reel or cut-length packaging as needed for your assembly process.
Selection Notes
Select this connector when a high-density, right-angle interface is required between two printed circuit boards. The 1.27mm pitch allows for compact layouts, while the gold plating supports repeated mating cycles. Consider mechanical constraints such as board thickness and mating height to ensure proper alignment and connection stability.
