It uses outer shroud contacts on a 0.020\" (0.50mm) pitch in two rows, with a mated stacking height of 3mm — a compact footprint for parallel PCB interconnects in tight z-height budgets. ## Key Specs for the Fit Check The 40 positions match a 40-circuit BOM line; the two-row layout keeps the connector width manageable. Termination is surface-mount only; no through-hole option for this variant.","metaTitle":"Hirose DF12D(3.0)-40DP-0.5V(81) Header, 40 Pos, 0.50mm","metaDescription":"Hirose DF12D(3.0)-40DP-0.5V(81) 40-position header, 0.020\" (0.50mm) pitch, 3mm stacking height, gold contacts.
