33ft Polarized Reflective
Photoelectric Beam Sensor
E-931-S33PRGQ
Installation Manual
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.
Polarized sensor is immune to shiny objects:
Triggers only when correctly reflected light is
detected
Weatherproof (IP55) construction
Anti-condensation housing
12-30V DC/AC 60Hz, 100mA
IMPORTANT:
The E-931-S33PRGQ conforms to UL Std. 325 for gate operators that use the N.C. or
10kΩ resistor for monitoring.
