Industrial Applications

1. High-Speed Packaging Conveyor Detection

Detects the presence, orientation, and size of small opaque items (down to Ø30mm) moving across rapid automated packaging lines.

Problem Solved

Prevents jams and miscounts on fast-moving conveyors by utilizing a rapid 7ms response time over a reliable 140mm sensing height.

2. Space-Constrained Assembly Machine Verification

Verifies the accurate placement and ejection of components within tight, automated pick-and-place assembly jigs.

Problem Solved

Eliminates false triggers caused by optical crosstalk using integrated mutual interference prevention, while fitting into extremely confined spaces thanks to its 13mm slim profile.

3. Poka-Yoke Manual Bin-Picking Guidance

Provides visual cues and verifies manual operator hand entry into correct parts bins during complex manual assembly tasks.

Problem Solved

Reduces human error in sequential part selection by utilizing a highly visible twin-LED JOB indicator that flashes to guide the operator and triggers a PNP signal upon correct entry.
