It uses a standard 0.100" (2.54 mm) square-pin grid on both pitch and row spacing, making it footprint-compatible with a wide range of legacy and current PCB layouts. The through-hole termination suits wave-solder assembly, and the 0.250" (6.35 mm) mating pin length provides good wipe depth for reliable contact with a matching receptacle.
The 30.0 µ" (0.76 µm) gold or GXT™ plating on the mating surface is specified for repeated mating cycles and corrosive environments — a step above the thin flash gold or tin found on commodity headers. Being unshrouded, this header relies on the mating receptacle housing for polarization and alignment — no built-in keying or latch.
