Industrial Applications

1. Precision PCB Component Alignment

Utilizing diffuse-reflective sensing at a 100 mm range, this sensor accurately detects passing printed circuit boards (PCBs) on high-speed conveyors. The 1 ms response time ensures that even tightly spaced boards are recognized individually without requiring reflectors.

Problem Solved

Eliminates the complexity and mechanical spacing needed to align separate retroreflective plates or receiver heads on dense electronics assembly lines.

2. High-Speed Bottling Conveyor Counting

The sensor detects opaque, translucent, or transparent beverage bottles on automated filling and packaging lines. With an integrated inverter countermeasure circuit, high-frequency electrical noise from nearby high-horsepower conveyor motor drives is suppressed.

Problem Solved

Prevents false-triggering and incorrect inventory counts due to EMF noise from adjacent variable frequency drives (VFDs).

3. Robotic End-of-Arm Tooling Part Verification

With a bare weight of only 50 g, the compact sensor is mounted directly onto automated robotic gripper assemblies. It verifies object presence at 100 mm before initiating picking or transport routines.

Problem Solved

Prevents collision damage and gripper dry-run errors while minimizing the dynamic payload weight penalty on robotic arm joints.
