Photocell/Reflective Light Sensor Dedra SA1E-LPP3C-SET with Polarization Filter, 10–30 V DC, 1 pcs

Dedra SA1E-LPP3C-SET is a reflective light sensor supplied as a single unit together with a polarization filter. Designed to operate from 10–30 V DC, this photocell detects reflected light to determine object presence and position. The included polarization filter helps reduce interference from ambient reflections and improves detection accuracy on shiny or specular surfaces, making the sensor suitable for industrial automation and workshop measurement tasks.

Advantages

The sensor combines a compact reflective photocell and a polarization filter in one package, simplifying installation and reducing the need for additional accessories. Wide operating voltage range (10–30 V DC) allows integration into common control systems and power supplies. Polarized detection minimizes false triggers caused by stray reflections and improves reliability when working with metallic or glossy objects. The single-piece supply format is convenient for replacement or scaling within existing setups.

Suitable for

• Object presence detection on conveyor belts and feeders
• Position sensing in assembly lines and pick-and-place systems
• Detection of shiny or specular surfaces where ambient reflections are problematic
• Workshop measurement rigs and prototype automation

Key specifications

• Type: reflective light sensor (photocell) with polarization filter
• Supply voltage: 10–30 V DC
• Delivered quantity: 1 piece (sensor with polarization filter)
• Main function: reflected light detection for presence and position sensing

How to use

Mount the sensor in a position where its optical axis faces the target surface and ensure the polarization filter is oriented according to the anticipated reflection angle. Connect the supply wires to a compatible 10–30 V DC source and interface the sensor output to your controller or relay input following the manufacturer’s wiring conventions. Adjust sensor position and, if available, sensitivity or focus settings to obtain stable detection without false triggers. Verify operation with representative target materials and ambient lighting conditions present during normal use.

Usage recommendations

For reliable performance, install the sensor with a stable mechanical mount and avoid direct exposure to strong ambient light sources that align with the sensor axis. When detecting highly reflective objects, test different polarization filter orientations and sensor-to-target distances to minimize spurious reflections. Regularly inspect the optical window and filter for contamination and clean with a soft, lint-free cloth to maintain consistent detection.
