The FS-ARR-40X40 pressure distribution sensor is a 1600-point array pressure sensor with 40 horizontal and 40 vertical sensing points. There is one sensing point every 2.1×2.1mm. The sensing point is 1.8×1.8mm, with a gap of 0.3mm between each sensing point. The resistance value of each sensing point decreases as the pressure acting on it increases. The interface adopts a 40PIN, 1.0 mm pitch plug-and-unplug interface, in X+Y mode. There are 40 pins in the horizontal direction and 40 pins in the vertical direction, with a pin spacing of 1.0mm. This design enables the RPPS-1600 system to quickly and accurately capture subtle pressure distribution changes, providing valuable data for various applications.
