Special Features

  • This sensor switch can be used for motor speed measurement, position detection, etc
  • Using 3144E switch type sensor for Good temperature performance, it has high accuracy and high reliability.
  • Wiring Instructions:VCC -power positive,GND -power supply negative,DO -TTL digital output,AO -analog output (different distance output, different voltage).
  • Work Voltage: 3.3-5V
  • When the sensor senses a magnetic field, the digital 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.
