Hirose Electric FX36 Series

The Hirose Electric FX36 Series is a compact, 0.5 mm-pitch floating board-to-board connector engineered for automotive and industrial systems exposed to vibration and PCB movement. Its floating structure absorbs misalignment of up to ±0.7 mm in both the X and Y directions, with an effective mating length of ±0.5 mm in the Z direction.

A two-point contact system and vibration-absorbing design help maintain stable electrical connections in demanding operating environments. Rated for temperatures from -40°C to +125°C, the connector supports applications including EV and HEV powertrains, inverters, converters, on-board chargers, electric power steering, and industrial machinery.

The series supports 40, 50, 60, and 80 positions, with 15 mm, 18 mm, and 20 mm stacking-height options. Its compact footprint enables high-density layouts and space-efficient board-to-board integration. Product configurations and availability vary by position count and stacking height.
