It uses the industry-standard 0.100" (2.54 mm) pitch and terminates via through-hole solder to the PCB. The mating side is finished with 100.0 µin (2.54 µm) of tin — a durable, cost-effective plating for moderate mating-cycle applications.
The 0.100" (2.54 mm) pitch is the classic breadboard-compatible spacing — any PCB footprint for this header must match that grid. The unshrouded design means there's no polarization key — it mates with standard female receptacles but offers no protection against off-angle insertion. The UL 94 V-0 rated black housing (0.100" insulation height) is standard for equipment inside an enclosure.
