Sick WTF18-3V910 Description



  • Sender LED with infrared light
  • Precise background suppression
  • Scanning distance can be set via potentiometer
  • Insensitivity to ambient light
  • Alarm output when sensors contaminated
  • Rugged plastic housing
  • Your benefits

  • Large scanning distances due to high-performance infrared light
  • Reliable object detection with high-precision background suppression thanks to second sender LED
  • Comfortable and fast scanning distance setting due to 4-speed potentiometer
  • No interference from ambient light or devices mounted opposite one another
  • High availability in the field thanks to alarm output
