The 57202-G52-23LF: Surface-mount termination means the solder tails reflow with the board, no through-hole staking needed. The push-pull fastening type keeps it simple: no latch, just a straight mate and unmate.
Current, Plating, and Contact Life
The 30.0 µinch (0.76 µm) Gold GXT™ on the mating face is a hard gold alloy that holds contact resistance stable through repeated mate cycles; the tin-plated posts (78.7 µinch / 2.00 µm) are the solder interface.
