Industrial Applications

1. High-Speed Parts Counting in Feeder Systems

Utilized in vibratory bowl feeders or gravity tracks to accurately register small, fast-moving components as they pass through the wide sensing gap.

Problem Solved

Prevents mechanical jams and counting errors in high-throughput lines by using ultra-fast infrared detection that responds in micro-seconds.

10 kHz switching frequency100 µs response time0.2 mm MDO

2. Edge Guiding in Web Processing

Mounted directly along the material web path, the deep slot monitors the exact edge position of continuous materials like paper, film, or foil.

Problem Solved

Eliminates lateral web drift and material tearing by instantly detecting deviations and signaling automated alignment correctors.

3. Label Dispensing Verification

Integrated into labeling and packaging machinery to consistently verify the presence of a label on its carrier web prior to application.

Problem Solved

Stops mislabeled or unlabeled products from reaching final packaging by reliably distinguishing between single and double material layers.
