Tips

For optimal performance, mount the sensor securely using the threaded barrel or a suitable bracket, ensuring the target passes within the specified detection range. Use the sensitivity potentiometer to adjust for different target colours or surface reflectivity. When connecting, verify the correct polarity and output configuration to match your control system. Regularly inspect the lens for dust or debris to maintain reliable detection.
