3144E Speed ​​Counter Module Magnetic Detect sensor


3144E sensor senses the magnetic field, If the digital output is low and the signal light is on; then no magnetic field is sensed. If the digital output is high and the signal light is on then the magnetic field is sensed and the effect sensor switch has a power indicator and a sign indicator. 3144 sensor has excessive sensitivity, speedy response, suitable temperature performance, high accuracy, and high reliability.

Features of 3144E Speed ​​Counter Module

  • Small size, it has high sensitivity and fast response
  • Good temperature performance, it has high accuracy and high reliability.
  • Using 3144E switch type sensor for stable performance
  • When the sensor senses a magnetic field, the di tal output is low and the signal light is on; if no magnetic field is sensed, the digital output is high and the signal is not lit.
  • This effect sensor switch has a power indicator and a signal indicator.
  • Good waveform and strong driving ability
  • It is provided with fixing bolt holes for easy installation and fixing.
  • Can be used for motor speed measurement, position detection, etc.
