Description
The E-931-S33PRGQ 33ft Polarized Reflective Photoelectric Beam Sensor provides reliable detection of shiny objects that could be missed by a non-polarized sensor.
- Polarized sensor is immune to shiny objects: triggers only when correctly reflected light is detected
- Weatherproof (IP55)
- Anti-condensation housing
- 12-30V DC/AC 60Hz, 100mA
- Up to 33ft (10m) sensing range
- Round reflector, Diameter: 3-1/4″ (82mm)
- Form C relay: 500mA@30VAC/VDC
- Beam status LED
- Compact size: 4-13/16″x2-3/8″x2-7/16″ (122x60x62mm)
- N.C. Tamper switch: 500mA@30VAC/VDC
- Monitored Outputs:
- N.C.
- 10kΩ Resistor
- Hood included for both sensor and reflector
Typical Applications
- Sensor for garage doors, outdoor gates or overhead doors
- Sensor for industrial automation to detect objects on manufacturing line

Troubleshooting
| 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
-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 |
