Industrial Applications

1. High-Speed Packaging Detection

Utilizes the 1,000 Hz switching frequency and background suppression to reliably detect small cartons on fast-moving conveyor belts while ignoring the reflective belt surface.

Problem Solved

Prevents false triggering caused by conveyor belts or background machinery in high-throughput packaging operations.
