Digital Fiber Optic Sensor Setting Method

Digital fiber optic sensors can be adjusted by calibrating sensitivity, setting thresholds, and using preset or fine-tuning functions to ensure accurate detection.Mounting and Initial Setup

• DIN Rail Installation: Align the sensor slot with the DIN rail and press it into place until securely mounted .
• Fiber Connection: Connect the optical fiber to the launch end and the multi-core fiber to the receiving end, ensuring proper alignment .

Sensitivity Calibration

• One-Point Calibration: Press the button twice to calibrate the sensor to the current light intensity .
• Automatic Sensitivity Adjustment: Some sensors allow automatic calibration while the workpiece passes through, useful for continuous line operations .
• Fine Adjustment: Use the manual or button to adjust the sensitivity to a desired threshold, compensating for dust, dirt, or light intensity variations .

Preset and Threshold Settings

• Preset Function: Press the button to set a reference value. Holding the button can disable the function .
• Threshold Range: Use 1-point or 2-point teaching to set the detection threshold. For 2-point teaching, select objects with different light intensities to define low and high thresholds .
• Percentage Calibration: Some sensors allow setting a percentage of light intensity (e.g., 10–15%) to define detection sensitivity .

Advanced Adjustments

• High-Speed Mode: Activate high-speed response (e.g., 50µs) via the and manual buttons for fast detection applications .
• Factory Reset: Press and hold and simultaneously for 3 seconds, then follow the display prompts to initialize the sensor .
• Key Lock Function: Lock settings to prevent accidental changes after calibration .

Practical Tips

• Always verify the sensor output after adjustments by testing with actual workpieces.
• Clean the fiber ends regularly to maintain consistent light intensity.
• Use the sensor's indicators (e.g., PST, DTM, and current display) to monitor calibration and detection status . By following these steps, you can ensure your digital fiber optic sensor is properly adjusted for accurate and reliable operation in your application.
