Industrial Applications

1. Automated Conveyor System Object Detection

In manufacturing and logistics, the CX-491 can accurately detect the presence and position of various objects, including those with shiny or reflective surfaces, on conveyor belts. Its 3-meter sensing range and polarized filter prevent false detections from reflections, ensuring precise material handling.

Problem Solved

Ensures reliable object detection on conveyor systems, even for materials that are typically challenging for standard sensors due to their reflective properties, preventing jams and ensuring continuous flow.
