It is an unshrouded, push-pull header on a 0.100" (2.54 mm) pitch — the standard grid for breadboard and legacy PCB layouts. Rated 5 A per circuit at 110 V, with a 30.0 µinch gold or GXT contact finish on the mating surface, it is built for board-to-board stacking applications where signal-level current and repeated mating cycles are the norm. The through-hole solder termination and UL94 V-0 black housing suit it for general-purpose PCB interconnect inside enclosed equipment.
The 0.100" (2.54 mm) pitch matches the standard perfboard and breadboard grid.
