32-Position Board-to-Board Plug at 1.27mm Pitch
The Hirose FX2C1-32P-1.27DSA(71) is a 32-position plug from the FX2 series, designed for board-to-board parallel stacking. The gold-plated contacts, at 7.87µin (0.200µm) thickness, are specified for signal-level duty where repeated mating cycles and corrosion resistance matter more than bulk current capacity. This is the vertical, through-hole version of the FX2 plug — the orientation keeps the mating axis perpendicular to the PCB, which is the standard for mezzanine or parallel board stacking.
For a 32-position, dual-row part at 1.27mm pitch, the board footprint requires a 2-row staggered hole pattern with a row-to-row spacing that matches the FX2 series standard.
The gold contact finish at 7.87µin (0.200µm) is a standard signal-grade plating for board-to-board interconnects. The center strip contact style means the signal contacts are arranged in a row along the center of the connector body, which keeps the signal path short and the impedance controlled for digital signaling up to moderate speeds.
