50-position dual-row board-to-board receptacle
Guide pin ears align the receptacle to the header during blind mating, which matters when the board stack has tight z-height clearance and you cannot see the pin tips engage.
ROHS3 compliant — the tin post finish and PPS insulation meet current environmental directives.
For a 50-position build, 5-534972-3 carries 38 more circuits than the 12-position sibling, with gold-on-gold mating interface versus tin-on-tin — a meaningful difference if the application cycles the connector more than a few times.
