Product details

0.40mm Pitch Mezzanine Receptacle, 50 Positions, 2.5mm Stack Height

The Hirose DF40HC(2.5)-50DS-0.4V(51) is a 50-position receptacle from the DF40 series of board-to-board mezzanine connectors, designed for dense parallel stacking where board real estate is at a premium. 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.
