The 0.016\" (0.40mm) pitch packs 50 circuits into a compact footprint, with a mated stacking height of 2.5mm that suits tight z-height budgets in portable electronics, handheld devices, and compact modules. Gold-plated center strip contacts (2.00µin thickness) handle repeated mating cycles typical of production assembly and field service.","metaTitle":"Hirose DF40HC(2.5)-50DS-0.4V(51) 50-Pos 0.40mm Pitch","metaDescription":"Hirose DF40 series receptacle, 50 positions, 0.40mm pitch, 2.5mm stack height.
