Installation Guide
- Mount the transmitter and receiver facing each other.
- Keep the detecting distance between 0.3 m and 15 m.
- Use optical synchronization. No sync line is required.
- Align both units within the effective angular aperture.
- Use series connection for up to 2 units.
- Set the interference prevention switch correctly.
- Connect the 24 VDC Class 2 supply.
- Wire the NPN OSSD outputs to the safety circuit.
- Check the IP65/IP67 seal after installation.
Setup and Maintenance Convenience
- Optical synchronization cuts wiring time.
- The metal housing resists impact and vibration.
- The IP65/IP67 rating allows washdown cleaning.
- Indicator LEDs show power and output status.
- Reverse-connection and short-circuit protection reduce damage risk.
- No moving parts inside. This lowers wear.
- Keep the front cover clean for stable detection.
