SC-22G5 is a dual-channel Hall speed sensor which designed and produced by our company. The sensor is installed on the end cover of the 1000-speed test and is used to detect the speed, linear speed, acceleration and vehicle running direction. The output waveform of the sensor is a square wave. It has no contact with the gear under test, no wear and easy installation. And the speed measurement range is wide, the temperature adaptation range is wide, and the shock resistance is strong. The following are the technical parameters when the modulus of the speed measuring gear is 2.0 and the direction of rotation of the gear is as shown in the figure (the gear meets the DIN867 standard).
