The FS-ARR-40×40-S20 pressure distribution sensor employs a 1600-point array, consisting of 40 horizontal and 40 vertical sensing points. Each point has a size of 0.5×0.5 millimeters, a resolution of 0.3×0.3 millimeters, and a point spacing of 0.2 millimeters. The resistance of the sensor decreases proportionally to the applied pressure. This sensor uses a 40-pin x+y interface with a pin spacing of 1.0 millimeters, and is structured with 40 horizontal pins and 40 vertical pins arranged in a horizontal and vertical manner.
