How to Use

1. Installation
   Mount in a fixed position facing a reflector (mirror or retroreflective tape) at a distance within 4 m.

2. Power & Wiring
   Supply with any voltage between 12 VDC or 20–260 VAC/DC according to your setup. Relay output ensures compatibility with various PLCs or control systems.

3. Adjust Sensitivity
   Use the integrated 270° trimmer to fine-tune detection range based on environmental needs.

4. Operation
   When the reflected beam is detected, the relay output activates. LED status indicators (if present) help during setup and diagnostics.

5. Maintenance Tips

   • Keep the lens and reflector free of dust or debris.

   • Ensure proper alignment with the reflector surface for consistent detection.

   • Avoid environments with extremely high EMI or physical shocks, despite the built-in protections.
