The contact finish is specified as Gold or Gold, GXT™ — the GXT variant is a harder gold alloy that extends mating cycle life beyond standard soft gold.
The mating pin length is 0.318" (8.08mm), and the post length below the insulator is 0.110" (2.79mm) — short enough to clear a standard 1.6mm board without protruding excessively on the solder side. The insulator stands 0.240" (6.10mm) above the board surface. Contact material is phosphor bronze, a spring-grade alloy that holds its shape through multiple mating cycles and resists stress relaxation at elevated temperatures.
