The Hirose DF40HC(3.0)-90DS-0.4V(51) is a 90-position receptacle from the DF40 series, built for board-to-board mezzanine stacking. It uses a 0.40mm pitch and a 2-row layout, with center strip contacts that keep the signal path short between stacked PCBs.
The mated stacking height is 3mm. This is the board-to-board gap when the receptacle is mated with its matching header, and it determines the z-height clearance in your enclosure.
