SECO-LARM ENFORCER E-931-S33PRGQ — 33ft Polarized Reflective Beam Sensor Specifications

Specification sheet for the SECO-LARM ENFORCER E-931-S33PRGQ 33ft Polarized Reflective Photoelectric Beam Sensor.

Overview

The E-931-S33PRGQ provides reliable detection of shiny objects that could be missed by a non-polarized sensor, thanks to its polarized design. A polarized sensor only triggers when correctly reflected light is detected, so shiny objects passing through the beam don't cause false triggers or missed detections the way they can with non-polarized sensors.

Features

• Polarized sensor immune to shiny objects — triggers only when correctly reflected light is detected
• Weatherproof (IP55) with anti-condensation housing
• 12–30V DC/AC 60Hz, 100mA
• Up to 33ft (10m) sensing range
• Round reflector, 3 1/4" (82mm) diameter, included
• Form C relay: 500mA @ 30VAC/VDC
• Beam status LED
• Compact size: 4 13/16" x 2 3/8" x 2 7/16" (122 x 60 x 62mm)
• N.C. tamper switch: 500mA @ 30VAC/VDC
• Monitored outputs: N.C., 10kΩ resistor
• Hood included for both sensor and reflector
• Sensor adjustable ±90° left/right and ±5° up/down

How Polarized Sensors Work

In normal operation, correctly reflected light returns to the sensor and the beam remains unbroken. A polarized sensor correctly triggers when a shiny object interrupts the beam, because it filters for properly reflected (polarized) light rather than any reflected light. A non-polarized sensor, by contrast, can fail to trigger when a shiny object is present, because stray reflections off the shiny surface can fool the receiver into thinking the beam is still intact.
