Quick Answer:
Short Answer
Roll-2-Roll sensors detect edges on virtually any material including clear films, porous nonwovens, metallic foils, glass, mesh, and abrasive materials—without recalibration.
Roll-2-Roll® Sensors use patented fiber-optic technology based on light scattering rather than light blocking. This means they detect the physical presence of the web edge regardless of optical properties.
Materials that work:
- Clear and transparent films
- Porous nonwovens
- Metallic foils
- Glass
- Mesh and perforated materials
- Rubber and textiles
- Carbon fiber
- Abrasive materials
The only challenging material is matte carbon black that absorbs infrared light without reflection—and even this can be addressed by angling the light source.
