Industrial Applications

1. Material Handling and Conveyor Systems

Precisely detect the presence or absence of packages, boxes, or components on a conveyor belt, ensuring proper spacing and preventing jams. The through-beam principle ensures reliable detection even for objects with varying colors or reflective surfaces, leveraging its 0-800mm sensing range and 100 Hz switching frequency.

Problem Solved

Prevents material pile-ups and ensures smooth flow in automated material handling, eliminating errors caused by optical sensor limitations with certain material types in dynamic industrial environments.
