The Hirose FX11LA-80S/8-SV(92) is an 80-circuit receptacle from the FX11 series, designed for board-to-board mezzanine stacking at a fixed 2 mm mated height. Gold-plated contacts (4.00 µ" thickness) handle signal-level current; the ground plate provides a low-inductance return path, and the board guide eases alignment during assembly. Solder retention features anchor the SMT terminations against reflow shear and vibration.
The FX11LA-80S/8-SV(92) is a receptacle with center strip contacts. It mates with the corresponding FX11 series header of the same 0.50 mm pitch and 80-position count to achieve the 2 mm mated stack height. Confirm the header part number against the board layout and position count.
The pitch is 0.020" (0.50 mm), and the mated stack height is 2 mm. The height above board is 0.065" (1.65 mm). These dimensions define the board footprint and the z-height budget for the mezzanine stack.
