64-Position Density and Board Footprint
The 1-5111008-2: The 0.100" row spacing matches standard IC socket patterns, so the board layout can share a common via grid with logic or memory devices.
Gold Mating Finish and Contact Reliability
The 30 µinch gold or gold-palladium plating on the mating face supports repeated connect/disconnect cycles without contact fretting — in a field-service harness that sees quarterly reconnects, that translates to decades of reliable signal transfer. The post finish is 100 µinch tin, which solders cleanly into through-hole pads and provides a corrosion-resistant interface at the board level.
