The contact accepts 18 AWG wire and carries a heavy 30.0µin (0.76µm) gold plating over brass, which is the sort of plating depth you spec when the connector lives in a corrosive atmosphere or sees frequent mate/unmate cycles in a test fixture or panel door. ## What the Gold Plating Means for Your Duty Cycle Tin or flash-gold contacts wear through after a few dozen cycles; this heavy gold layer keeps the contact resistance stable well past 500 cycles in benign environments, and it resists the sulfide tarnish that creeps into industrial cabinets. If you're replacing a contact in a harness that gets plugged and unplugged regularly — say a programming port or a test point — this is the right grade.","metaTitle":"TE 66570-8 AMPLIMITE HDP-20 Stamped Pin Contact, 18 AWG","metaDescription":"TE Connectivity 66570-8 AMPLIMITE HDP-20 stamped pin contact. 18 AWG wire, solder cup termination, 30.0µin gold plating.
