Sick WL27-3P3402S17 Overview



Reflex Array Sensor

Sick WL27-3P3402S17 Description



  • Detection of objects > 12 mm in 50 mm high band of light regardless of location
  • Detection of objects > 5 mm in 24 mm high band of light regardless of location
  • Scanning range for detection from 0 m to maximum 4.5 m
  • Minimum distance between sensor and reflector 0.5 m
  • PinPoint technology for intensive red light
  • Automatic adaptation of the switching threshold when there is soiling
  • Your benefits

  • Detection independent of location in a 50 mm band of light (MDO: > 12 mm) or 24 mm band of light (MDO: > 5 mm)
  • Reduces required installation work by up to 50% compared to light grids or multiple photoelectric sensors
  • PinPoint technology and optical alignment aids for simple and quick commissioning
  • Less downtime due to automatic adjustment of switching threshold
