It uses the standard 0.100" (2.54mm) pitch — the same spacing as classic breadboard and 0.1" prototype grids, so the footprint drops onto a standard perfboard or 0.1"-center PCB layout without adjustment. Rated 5A per contact at 110V, with gold or GXT™ plating on the mating surface at 30.0µin (0.76µm) thickness. This is a signal-grade interconnect — the current per pin is generous for logic-level or low-power DC lines, but the unshrouded design and 2.54mm pitch keep it in the board-to-board signal space, not a high-current power bus.
The 0.100" (2.54mm) pitch is the primary footprint driver — it matches the industry-standard 0.1" grid, so the PCB layout is a straight row of 5 plated through-holes on 2.54mm centers. The 5A per-contact rating is the thermal ceiling at 25°C; in practice, if you're running all five pins near the limit in a tight enclosure, derate per the manufacturer's curve.
