E-931-S33PRGQ

Polarized Reflective Photoelectric IR Beam Sensor, 33ft, ETL

The ENFORCER E-931-S33PRGQ 33ft Polarized Reflective Photoelectric Beam Sensor provides reliable sensing of shiny objects that enter the space between the sensor and reflector, thus breaking the infrared beam. It is suitable for various types of 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 objectChange 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

-Adjust the reflector and/or sensor for proper alignment
