EX-20 series sensors expand our innovative and super slim photoelectric sensors which combine high performance and miniature design. EX-20 sensors can be fastened with M3 screws. Moreover, metal inserts have been provided in the mounting holes, thus the sensor will not be damaged even if the screws are overtightened.


  • Response time only 0.5ms
  • Red LED
  • New: up to 35% less power consumption
  • New: improved ambient light immunity
  • Thru-beam
  • Diffuse reflective (fixed focus)
  • Sealed to IP67
  • Two-color indicator LED
  • Checking protrusion of wafer
  • The ultra compact photoelectric sensor EX-23 has a sufficiently long sensing range of 2m. Further, its visible red LED beam makes beam alignment very easy.
  • Detecting tape feeder cassette out of position
  • Ultra compact in size with an ample sensing range of 2m, ideal for monitoring tape feeder cassettes that are out of position.
  • Detecting fill-up of parts in feeder
  • The sensor setting can be finely adjusted since a universal sensor mounting bracket is available, with which the height and the angle of the sensor can be freely adjusted.
