Contact Interface and Mating Cycle Life
The 75867-101LF: The mating contacts carry 30.0 µinch (0.76 µm) of GXT gold over the phosphor bronze base. GXT is a palladium-nickel alloy with a gold flash — it wears harder than straight gold and resists corrosion in humid or mildly aggressive environments.
Housing and Shrouding
A keying slot in the housing prevents mis-mating with non-keyed receptacles.
