Board-to-Board Stacking: DF17(3.0)-26DS-0.5V(57)
The Hirose DF17(3.0)-26DS-0.5V(57) is a 26-position, 2-row receptacle with center strip contacts, part of the DF17 series of board-to-board mezzanine connectors. Typical applications include stacking PCBs in portable electronics, industrial control modules, and compact sensor assemblies where board spacing is tight. The mated stacking heights are 5mm, 5.5mm, and 7mm — that range gives the board layout engineer flexibility to set the z-height without changing the receptacle footprint.
