W4F Miniature Photoelectric Sensors

07 Apr 2021

With the intuitive “BluePilot” operating concept, sensors of the W4F product family can be aligned particularly conveniently and precisely. The blue LED display gives the user direct feedback for optimal alignment. The photoelectric sensors can be precisely adjusted in a very short time via a push-turn mechanism. In addition, BluePilot provides a visual indication if the detection quality should drop due to contamination or vibration, allowing faults to be corrected early on and preventing unplanned system downtime.


  • Solution for particularly challenging detection tasks in tight installation spaces
  • Very high reliability through powerful background suppression and excellent detection of flat, highly-reflective and transparent objects
  • Two switching points as well as the output of distance values expand the application possibilities
  • Flexible use thanks to high optical reliability
  • The highly-visible light spot combined with the intuitive BluePilot operating interface enables set-up in mere seconds
  • Maximum monitoring and process reliability thanks to intelligent monitoring and predictive maintenance
  • As Smart Sensors, fit for Industry 4.0
