It uses a 0.100" (2.54 mm) pitch and through-hole solder termination, with square pins made of phosphor bronze.
The 0.100" pitch is the standard 2.54 mm grid — the board footprint matches legacy perf-board layouts and common IDC receptacles. 5 A per contact is typical for signal-level and moderate power; the limiting factor is the temperature rise in the unshrouded housing rather than the contact itself. The 15.0 µin gold mating finish gives enough plating for several hundred mating cycles in a clean environment, and the UL94 V-0 housing meets the flammability requirement for equipment inside an enclosure.
