It uses outer shroud contacts in a 2-row arrangement on a tight 0.020\" (0.50mm) pitch, with a mated stacking height of 4mm and a height above board of 0.130\" (3.30mm). The gold-plated contacts and surface-mount termination suit it for high-density signal interconnects where repeated mating cycles and reliable contact are needed — think portable electronics, camera modules, or any compact stack-up where the board-to-board gap is tight and the pin count is high. ## Board Layout and Stack-Up Fit ## Mating and Termination Check This is a surface-mount header with outer shroud contacts, intended to mate with a DF12 series receptacle of the same 40-position count and 0.50mm pitch. The 4mm stacking height is fixed by the header's own height above board and the mating receptacle's profile — the pair together defines the board-to-board gap.","metaTitle":"Hirose DF12D(4.0)40DP0.5V80 Header, 40 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12 series 40-position header, 0.50mm pitch, 4mm stacking height, gold contacts, SMT.
