SZGB-4A SZGB-4B Speed sensor

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