The mating contacts are finished with 200.0µin (5.08µm) of silver — a thick layer that handles frequent connect/disconnect cycles better than standard tin or thin gold flash. Silver also offers low contact resistance, though it tarnishes over time; the wiping action during mating clears surface oxides.
