Reflective Photoelectric Beam Sensor, ETL UL325 Compliant, 50ft

E-931-S50RRGQ

Reflective Photoelectric Beam Sensor, ETL UL325 Compliant, 50ft

The ENFORCER E-931-S50RRGQ 50ft Reflective Photoelectric Beam Sensor provides reliable sensing of objects that enter the space between the sensor and reflector, thus breaking the infrared beam. It is suitable for various types of such as detection such as sensing approaching vehicles to open a garage door or outdoor gate, as an entry notification for stores, to assist in measuring parking distances, or an alarm notification, as well as many other uses.

Sensor does not detect the object.
  • Change the angle of the sensor or readjust the sensitivity setting
The beam sensor LED will not turn green
  • Clean the sensor and reflector with a damp (not wet) cloth
  • Apply a coating of RainX™ to the reflector and the face of the sensor to help keep the units clear of moisture.
  • Adjust the reflector and/or sensor for proper alignment
Beam sensor LED lights when object is detected, but there is no output.
  • Check wiring between the sensor and local alarm device.​
