It uses a 0.020\" (0.50mm) pitch and two rows of outer shroud contacts, with a mated stacking height of 5mm — a common z-height for compact parallel PCB assemblies in portable electronics, camera modules, and handheld instruments. ## 40 vs 30 vs 60 Positions — Same Footprint, Different I/O The DF12 series offers this header in 30, 40, 50, and 60 positions at the same 0.50mm pitch and 5mm stacking height. The 40-position DF12NC(5.0)-40DP-0.5V(51) sits between the 30-position DF12NC(5.0)-30DP-0.5V(51) and the 60-position DF12NC(5.0)-60DP-0.5V(51).","metaTitle":"Hirose DF12NC(5.0)-40DP-0.5V(51) Header, 40 Pos","metaDescription":"Hirose DF12 series header, 40 positions, 0.50mm pitch, 5mm stacking height, SMT, gold plating.
