The 6-102570-1: It is a through-hole, right-angle component with a shrouded 4-wall design and a detent lock for secure mating. The gold-plated mating surface (15.0µin) supports repeated mating cycles without corrosion, while the tin-plated posts (100.0µin) solder reliably into plated through-holes.
What the 3 A rating and gold plating mean for your board
The 3 A per contact rating is the thermal limit at 25°C ambient; derate for elevated temperatures inside an enclosure. The gold-on-phosphor-bronze contact (15.0µin gold over 100.0µin tin on the post) is built for moderate mating cycles — typical for a board-to-board or cable interconnect that sees periodic reconnection during service. The 0.400" (10.16mm) insulation height provides clearance for routing traces under the body.
