It uses a 0.016\" (0.40mm) pitch across two rows and mates to a matching header to achieve a 2.5mm mated stacking height — that's the gap between the two PCBs when mated. Typical applications include handheld devices, portable electronics, and any compact assembly where the board stack height budget is tight.","metaTitle":"Hirose DF40HC(2.5)-40DS-0.4V(58), 40 Pos, 0.40 mm Pitch","metaDescription":"Hirose DF40 series receptacle, 40 positions, 0.40 mm pitch, 2.5 mm mated stacking height, SMT, gold contacts.
