SZGB-4A, 4B photoelectric speed sensor

SZGB-4A, 4B photoelectric speed sensor is a small enclosed speed sensor using infrared photoelectric device structure, which has the advantages of large power supply range, low power consumption, long life, strong anti-interference ability, and long transmission distance. When in use, it is connected to the measured shaft through a coupling. When the shaft rotates, the angular displacement is converted into an electrical pulse signal for use in secondary instruments.
