SICK WL27-3R2631 Overview



Photoelectric reflex switch WL27-3R2631 red light, relay, rectangular plug, 6 pins, time delay

SICK WL27-3R2631 Description



  • High scanning range, high operating reserves
  • Faster alignment with red light
  • Reliable operation in industrial environments and when devices are mounted opposite one another
  • Front screen heating, time functions
  • Operating temperature: -40 C - +60 C
  • UL approval
  • Your benefits

  • Less downtime plus resistance to contamination due to high operating reserves
  • Flexible usage due to extended functionality e.g. time functions
  • Extremely vibration resistant and therefore largely independent of ambient conditions
  • For use at temperatures as low as 40 C
  • Highly stable housing due to offset fixing holes
