40-circuit breakaway header, C-Grid 70280
The 0702800688: Mating contacts are gold-plated (30.0µin) on a copper alloy square pin; the post receives tin (74.8µin). Through-hole solder termination, push-pull fastening, black LCP housing rated UL94 V-0.
Board fit and unshrouded layout
Unshrouded breakaway headers allow the board designer to snap the pin strip to the exact circuit count needed — the 40-position 0702800688 can be broken into shorter sections, though the full 40-position strip ships as a single unit. The 0.090" (2.29mm) insulation height keeps the header low above the board.
