Industrial Applications

1. Close-Range Transparent Object Sensing on Conveyor Lines

Using the 4-level emission power adjustment (down to Level 1, which is 20% of maximum power), the sensor prevents light saturation when detecting transparent films or thin glass plates at very close range.

Problem Solved

Eliminates false detections caused by optical receiver saturation when sensing transparent or highly reflective objects in close proximity.

2. Dense Multi-Sensor Array Packaging Machinery

Leverages the ultra-slim 9 mm profile and built-in 4-unit interference prevention (by adjusting emission frequencies 1 through 4) to install multiple FX-102P units side-by-side on tight DIN rails without cross-talk.

Problem Solved

Prevents mutual optical interference and reduces physical cabinet footprint in dense multi-point automated inspection systems.

3. Dust-Prone Industrial Environmental Part Detection

Utilizes the automatic threshold follow-up cycle setting function in Dark-ON mode to periodically recalibrate the threshold value, compensating for gradual dust accumulation on the fiber heads.

Problem Solved

Reduces maintenance downtime and manual cleaning cycles in harsh, dusty manufacturing environments by automatically adapting to ambient degradation.
