Q26 Series Clear Object Sensor


Sensor solution for clear object detection applications. The Q26 cannot be tricked by mirror-like surfaces and has precise leading edge detection.

  • Clear, transparent objects reliably detected
  • Polarized retro coaxial optical design enables detection of mirror-like surfaces; allows sensor and reflector to operate at very short distances; enables very precise leading edge detection
  • LO/DO switch, single turn sensitivity potentiometer, compact housing
  • Quick and easy adjustment of sensitivity with single-turn potentiometer
  • Compact housing fits in tight locations and 20mm mounting hole spacing enables quick mechanical installation
