It's a board-to-board interconnect on a standard 0.100" (2.54 mm) pitch — the workhorse spacing for prototyping and production layouts alike. Rated 5 A per circuit at 110 V, with 30.0 µ" (0.76 µm) gold or GXT™ plating on the mating surface, it's built for repeated mating cycles and moderate environments. The through-hole solder tails and push-pull mating style keep the footprint simple: no locking latches, no shrouding to route around.
The 0.100" (2.54 mm) pitch and 0.100" (2.54 mm) row spacing define the board footprint — two rows of square pins on a standard grid that matches virtually any 0.100" pitch receptacle. The 5 A per circuit rating is per-contact at the stated voltage; for a 4-position header that's 20 A total across the connector, but the real limit is the temperature rise in your enclosure, not the contact itself. The 30.0 µ" (0.76 µm) gold plating on the mating side is the key reliability spec — it supports hundreds of mating cycles without fretting corrosion, making this header suitable for field-serviceable connections or test points, not just a one-time solder joint. The unshrouded design means no keying or polarization: you can mate it with any standard 0.100" pitch female receptacle, but there's nothing to prevent a 180° misalignment during blind mating.
This header mates with any standard 0.100" (2.54 mm) pitch dual-row female socket — the BERGSTIK II receptacle housings or any industry-standard box header. The 0.770" (19.56 mm) mating pin length gives plenty of wipe for a secure connection. Termination is through-hole solder: the 0.120" (3.05 mm) post length suits standard PCB thicknesses around 0.062" (1.6 mm). The overall contact length of 0.990" (25.15 mm) means the pins sit well above the board for easy probing or manual wiring.
