This is a standard-density, push-pull unshrouded header — no locking latch, no keying — meant for low-vibration, internal board stacking where the mating receptacle provides the retention.
The 0.100" (2.54mm) row spacing is the standard BergStik pitch — it matches the footprint of any 0.100" dual-row receptacle, including the common 65863, 65039, and 78211 series housings. The tin-on-tin contact finish is rated for 5A per pin, but the limiting factor for tin is mating cycle life — expect a few dozen cycles before fretting corrosion becomes a concern. The 0.380" (9.65mm) mating length gives enough pin exposure for standard receptacles; the 0.120" (3.05mm) post length fits a typical 0.062" board.
