What This Connector Does in a Board Stack
The Hirose DF12-50DS-0.5V(80) is a 50-position, 0.50mm-pitch receptacle with center strip contacts, designed for board-to-board mezzanine stacking in compact electronics.
The DF12-50DS-0.5V(80) is listed as Obsolete. That means Hirose no longer manufactures this exact order code.
The 0.50mm pitch is tight — it routes well for dense digital signals but leaves little creepage for high-voltage lines, so treat it as a signal-only interconnect. The mated stack height range (3.5mm, 4mm, 5mm) comes from the matching header's height; the receptacle itself sits 2.70mm above the board. Gold contact finish handles the mating cycles typical of production and field-service reconnects without fretting corrosion.
