452 Series 1.27mm Shrouded Board-Mount Headers

3M 452 Series 1.27mm (0.050") Shrouded Board-Mount Headers are compact, robust mating connectors in a fine-pitch system allowing high connection density in a small space. A shroud or four-wall box protects two rows of copper alloy pins spaced 1.27mm apart. 30μ" gold and gold flash plating options are available on the wiping area for multiple mating/unmating cycles and price points according to engineering requirements and budget. Optional latches on the 3M 452 Shrouded Board-Mount Headers provide a mechanical means to secure the mating socket connector during use or remove it for maintenance or repair. Designers can select from vertical or right-angle versions with thru-hole solder tails. Gull-wing solder tails are offered for surface-mount processing and tape and reel packaging to enable high-volume manufacturing.
