Industrial Applications

1. Conveyor Belt Monitoring in Packaging Plants

Detecting the presence or absence of metallic packages or components on a conveyor belt in packaging lines.

Problem Solved

Ensures accurate product counts, prevents jams, and confirms product flow. Its IP67 rating makes it suitable for environments with dust or moisture, while non-contact operation prevents wear on products. The 8mm sensing distance allows for reliable detection of moving objects.
