52-Position Board-to-Board Plug at 1.27 mm Pitch
The Hirose FX2CA-52P-1.27DSA(71) is a 52-position plug from the FX2 series, designed as a board-to-board interconnect with center strip contacts.
Through-Hole Termination and Dual-Row Layout
The two rows of contacts, 26 per row, bring the total to 52 positions. The connector style uses center strip contacts, meaning the mating interface is a row of flat spring contacts that wipe against the receptacle's pads. This is typical for mezzanine stacking where the mated pair sits parallel to the board.
