Explosion-Proof Photoeye

  • Thru beam configuration
  • Wide sensing angle for increased reliability
  • 115 ft. operating range
  • NEMA 4X enclosure


Designed for explosive environments, the rugged IRB-EXP explosion proof photo beam is used as a safety, reversing, or opening device in conjunction with automatic operators. The IRB-EXP explosion proof photo beam sensor features a 24° sensing angle for easy installation and alignment and 115-ft. operating range.

The lens-less design of the IRB-EXP makes it less sensitive to fog, dust, snow and sunlight, making it a more accurate explosion-proof photoeye.
