The Hirose DF40HC(2.5)-40DS-0.4V(58) is a 40-position receptacle from the DF40 series, designed as a board-to-board mezzanine interconnect. It uses a 0.016" (0.40mm) pitch across two rows and mates to a matching header to achieve a 2.5mm mated stacking height — that's the gap between the two PCBs when mated. Typical applications include handheld devices, portable electronics, and any compact assembly where the board stack height budget is tight.
