Sunx Through-beam Fiber Optic Sensor Adjustment Method

Proper adjustment of Sunx through-beam fiber optic sensors involves aligning the emitter and receiver, setting the threshold value, and fine-tuning the light output for optimal detection. Step 1: Physical AlignmentPosition the emitter and receiver fibers directly opposite each other along the intended sensing path. Ensure the beam is unobstructed and the fibers are securely mounted ( ).

For fibers with expansion lenses or multiple cores, carefully adjust the alignment to avoid beam narrowing or misalignment, especially for long-distance sensing ( ). Avoid sharp bends in the fiber sleeve, as this can reduce the sensing range and affect detection accuracy ( ). Step 2: Initial Power and Light OutputPower on the sensor amplifier and check the incident light intensity on the receiver.

If the intensity is too high (saturated), reduce the light-emitting amount using the amplifier's light output adjustment function ( ). Ensure the response time is not affected by light output adjustments ( ). Step 3: Threshold Value SettingEnter SET mode on the amplifier by pressing the MODE key for 2 seconds ( ).

With no object in the beam path, press the ON key to set the background reference. The green digital display will indicate the incident light intensity ( ). Adjust the threshold value so that the sensor reliably detects objects while ignoring background light or reflections ( ).

For small or transparent objects, fine-tune the receiving sensitivity to one of the available levels for optimal detection ( ). Step 4: Verification and Fine-TuningTest the sensor with the actual target objects to ensure consistent detection. If multiple fibers are used side-by-side, set different emission frequencies to prevent interference ( ).

Check for reflective surfaces near the fiber head; if interference occurs, adjust the threshold value accordingly ( ). Step 5: Maintenance TipsPeriodically verify alignment and threshold settings, especially in environments with vibration or temperature fluctuations. Use the digital display to monitor the current light-receiving amount and adjust as needed for consistent performance ( ).

Avoid bending or stressing the fiber cables beyond their specified limits to maintain sensing range and accuracy ( ). By following these steps, Sunx through-beam fiber optic sensors can be accurately adjusted for reliable detection in industrial automation applications.
