The Hirose FX2CA2-52S-1.27DSA(71) is a 52-position board-to-board receptacle from the FX2 series, designed for parallel PCB stacking at a 1.27 mm pitch. Gold-plated contacts at 7.87 µin (0.200 µm) handle moderate mating-cycle duty; the through-hole termination keeps the solder joint robust for production reflow or selective wave assembly.
This is a board-to-board receptacle, so it mates with a matching FX2 series header of the same 1.27 mm pitch and position count. The specific header part number depends on the required stack height and orientation — check the FX2 series product drawings for the compatible header variant.
