The Hirose DF40HC(3.5)-30DS-0.4V(51) is a 30-position receptacle from the DF40 series of board-to-board mezzanine connectors, designed for parallel PCB stacking at a fixed 3.5 mm mated height. Gold-plated center strip contacts with a 2.00 µin finish handle moderate mating cycles typical of internal board stacks.
The mated stacking height is 3.5 mm, as specified in the part number. This is the fixed board-to-board gap when mated with the corresponding DF40 series header.
