The Amphenol FCI 75160-110-06LF is a 6-position, single-row BERGSTIK® board-to-board header on the standard 0.100" (2.54mm) pitch. It's an unshrouded, through-hole, push-pull style male pin header with gold GXT™ 30.0µin (0.76µm) plating on the mating surface — the thick gold layer handles repeated mating cycles without the contact fretting you'd see with tin on a board that gets reworked.
The phosphor bronze contacts with 30µin gold give good spring retention and corrosion resistance across the -65°C to 130°C operating range, which covers most industrial cabinet and outdoor telecom gear.
