28-Position BergStik II Unshrouded Header
All 28 positions are loaded, so the pin count on the BOM line is the pin count on the board. That thick tin finish handles repeated mating cycles in moderate environments — think test equipment, industrial control panels, or internal board stacking where gold is overkill and the budget matters. The insulation height is a low 0.100" (2.54 mm), which keeps the profile tight above the PCB.
The 0.100" (2.54 mm) pitch is the defining dimension for board layout — it matches the vast majority of BergStik and legacy.025" square-post receptacles. The through-hole termination uses a 0.120" (3.05 mm) post length, which suits standard 0.062" PCBs.
