Contact system and plating grade
The 65863-272 is the 50-position member of the Quickie™ header line, a shrouded dual-row board-to-cable/wire connector with male square pins in phosphor bronze. Mating contacts are gold or GXT™ plated to 30.0µin (0.76µm) — the gold grade supports repeated mating cycles in corrosive environments without contact resistance drift.
