The 1.27 mm pitch packs 52 circuits into a dual-row layout, suited for dense signal interconnect in backplane or mezzanine applications. ## Through-Hole Termination and Mounting Termination is through-hole solder, with the plug body sitting vertically on the board. The 1.27 mm pitch requires a PCB footprint with 0.050-inch (1.27 mm) staggered or inline pads depending on the layout guide. The board lock feature adds mechanical retention during wave soldering and in the final assembly under vibration. The plug mates with the corresponding FX2 receptacle, forming a low-profile board-to-board interconnect. Gold contact finish at 7.87 µin (0.200 µm) is a mid-grade plating for signal-level current and moderate mating cycles — typically 50 to 200 cycles depending on the application environment. The gold layer prevents oxidation on the mating interface, keeping contact resistance stable in low-energy signal circuits. For power applications, the per-contact current rating is limited by the narrow pitch and the housing thermal limits; the FX2 series is primarily a signal interconnect.","metaTitle":"Hirose FX2BA-52PA-1.27DSAL(71) Plug, 52 Pos, 1.27 mm","metaDescription":"Hirose FX2 series plug, 52 positions, 1.27 mm pitch, through-hole solder, gold contacts, board lock.
