The 0.50 mm pitch and outer shroud contacts make it a compact interconnect for parallel PCB assemblies in space-constrained electronics — think handheld devices, portable instrumentation, or any stack where the z-height budget is tight. Gold plating on the contacts suits the moderate mating-cycle duty of internal board stacks. ## What the 0.50 mm Pitch and 3.5 mm Stack Mean for Your Board The 0.50 mm pitch sets the center-to-center spacing between adjacent contacts. The 3.5 mm mated stacking height defines the gap between the two parallel boards.","metaTitle":"Hirose DF12(3.5)40DP0.5V(80 Header, 40 Pos, 0.50mm, Obsolete","metaDescription":"Hirose DF12(3.5)40DP0.5V(80 SMT header, 40 positions, 0.50mm pitch, 3.5mm stacking height.
