The mating connector in the fine-pitch system from 3M is the Shrouded Boardmount Header, 452 Series. A shroud or four-walled box protects two rows of copper alloy pins spaced 1.27 mm apart. Customers can choose from 30μ” gold and gold flash plating options on the wiping area for multiple mating/unmating cycles and price points according to engineering requirements and budget. Optional latches provide a mechanical means to secure the mating socket connector in place during use, or to remove it for maintenance or repair. Designers can select from vertical or right-angle versions with thru-hole solder tails. Gullwing solder tails are offered for surface-mount processing and tape and reel packaging to enable high volume manufacturing.
