• GP2Y0A21YK0F Infrared Distance Sensor

GP2Y0A21YK0F is a distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector) , IRED (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.


  • Distance measuring range : 10 to 80 cm (0.33 feet to 2.66 feet)
  • Analog output type
  • Package size : 29.5×13×13.5 mm
  • Consumption current : 30 mA
  • Supply voltage : 4.5 to 5.5 V


  • Touch-less switch (Sanitary equipment, Control of illumination, etc. )
  • Robot cleaner
  • Sensor for energy saving (ATM, Copier, Vending machine)
  • Amusement equipment (Robot, Arcade game machine).
  • Automatic Door opener
  • Human presence detection in a room
