EMX IRB-4X photo eyes safety sensors no cover hoods

Infrared Photocell IRB-4X without the hoods
Works without lenses so it is easy to align, making it less sensitive to fog, dust, snow, and sunlight. Used as a safety, reversing, or opening device in conjunction with automatic operators.


  • The IRB-4X transmitter and receiver are mounted in line of sight at a distance of up to 75 feet. When the infrared beam is broken the internal relay is de-energized and detection signal is produced on the relay contacts. The red LED indicator on the receiver is lit when the IRB-4X receiver is not aligned or when the beam is interrupted.
