Its 0.50mm pitch and surface-mount termination suit dense PCB layouts where z-height is tight — the mated stacking heights of 3.5mm, 4mm, and 5mm give three board-spacing options from a single connector footprint. Gold-plated contacts (8.00µin) on both mating surfaces handle moderate-cycle signal interconnects inside portable electronics, industrial control modules, and telecom line cards. The 0.50mm pitch drives a fine-pitch footprint — the board layout needs tight trace routing and a solder mask defined pad. The 50 positions in two rows give 25 per row, which keeps the connector body narrow enough for edge-of-board placement. Gold plating at 8.00µin is standard for signal-level interconnects; it resists corrosion and supports a few hundred mating cycles, but it is not rated for high-current power duty.","metaTitle":"Hirose DF12A-50DS-0.5V(81) 50-Pos 0.50mm Receptacle","metaDescription":"Hirose DF12A-50DS-0.5V(81) 0.50mm pitch, 50-position, 2-row receptacle.
