Photoelectric Sensor for Gap Detection


ML6 series sub-miniature photoelectric sensors come with dual sensor redundant detection and independent outputs. They are also available in long-range background suppression sensing models, and retro-reflective models with no sensing dead band. Because it acts like two sensors in one housing, you can align or guide translucent paper, plastic, and fabric webs.  When the web is properly positioned, one beam detects the web while the other beam does not.  Using this sensor, you can detect a gap between two objects to suppress the detection of small particles such as textile fibers.


  • Integrated cross-talk immunity to make side-by-side mounting possible
  • Tamper-proof design
  • 4-in-1 output to reduce inventory and wiring
  • Superior immunity to ambient light even for high frequency energy-saving lights
  • Diagnostic LEDs in the front and back of the housing for clearly visible status indication
  • Metal reinforced mounting holes for easy installation.
