SGD31-GG-TZ2B2P elevator leveling sensor photoelectric switch

‌The main function of the elevator leveling sensor is to ensure that the elevator stops accurately at each floor, that is, leveling positioning. ‌It helps the elevator stop accurately when it reaches the specified floor by detecting the position of the elevator car in the shaft. The leveling sensor is usually installed on the top of the elevator car, and a leveling plate is installed at each floor station of the elevator shaft. When the elevator car enters the leveling area, the leveling sensor will detect the signal of the leveling plate, thereby controlling the elevator to stop accurately.
