## Question

Do Roll-2-Roll sensors require recalibration when changing materials?

## Short Answer

No. Roll-2-Roll sensors require zero recalibration when switching between materials—switch from clear film to metallic foil instantly with no adjustment.

## Detailed Answer

Unlike traditional sensors that require recalibration for each material type, [Roll-2-Roll® Sensors](https://r2r.tech/products/sensors) use adaptive edge detection algorithms that automatically adjust to different material characteristics.

This eliminates:

- Manual gain adjustments
- Teach mode procedures
- Operator-dependent settings
- Extended changeover times

**The impact:** Plants using legacy sensors typically lose 2 hours monthly to recalibration—time that [Roll-2-Roll Technologies](https://r2r.tech) technology completely eliminates.
