The Hirose FX2BA-52PA-1.27DSA(71) is a 52-position plug from the FX2 series, designed as a board-to-board interconnect with a 1.27 mm pitch. It uses center strip contacts arranged in two rows, terminated by through-hole soldering into the PCB. The gold-plated contacts (7.87 µin / 0.200 µm) provide reliable signal connections in applications like industrial controllers, test equipment, and telecom backplanes where a compact, high-density parallel board stack is needed.
Key Ratings and Fit Decisions
The 1.27 mm pitch is the primary footprint constraint — it dictates the board layout and limits the routing channel width between pads.
