2. Transparent Material Sensing in Bottling and Pharmaceuticals

Leveraging its transparency recognition feature, this fiber optic sensor precisely identifies clear glass bottles, plastic vials, or transparent films in bottling, pharmaceutical, and food processing lines. The integrated display allows for precise threshold adjustments to optimize detection for varying degrees of transparency.

Problem Solved

Provides robust detection of clear or translucent objects that are traditionally challenging for standard photoelectric sensors, reducing false negatives and ensuring quality control in sensitive applications.
