The gold flash finish on the contact surface provides enough corrosion protection for field-service connections without the cost of a heavy gold plate; it's a good match for equipment that sees occasional mate-unmate cycles rather than production-line daily mating. ## Wiring it right — termination and housing fit If it backs out, it's scrap — the stamped lance is single-use, so a partial insertion means a new pin. The gold flash contact finish is thin enough that repeated insertion into a housing with worn retention features can scrape the plating, so inspect the housing latch windows before loading a full harness.","metaTitle":"TE 1658540-3 AMPLIMITE HDP-20 Pin Contact, Gold Flash","metaDescription":"TE 1658540-3 stamped pin contact for AMPLIMITE HDP-20 series.
