GP2Y0A41SK0F is a distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector), IR-LED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor.

Technical Specification:

  • Model: GP2Y0A41SK0F 4 to 30 cm
  • Operating Voltage: 5 ~ 5.5VDC
  • Distance measuring range:4 ~ 30cm
  • Connecting cable Length:15cm
  • Operating Temperature Range: -10 to 60°C
  • Response Time: 38 ± 10ms
  • Size: 44mm*18.5mm*13.5mm (L*W*H)


  • Based on the principle of triangulation
  • Output is inversely proportional to distance
  • Analog output, requires microcontroller control with AD converter
  • The higher the AD number, the more accurate the distance measurement effect


  • Cleaning robot
