Mating Interface and Plating
The male pins are rectangular brass with 14.5 µinch gold over nickel on the mating face — rated for repeated connect/disconnect cycles without the fretting corrosion you'd see with tin. The shrouded 2-wall housing with a detent lock keeps the mating half aligned and resists vibration-induced separation.
