## Question

Can the same Roll-2-Roll® Sensor do both edge guiding AND line guiding?

## Short Answer

Yes. A single Roll-2-Roll sensor handles both edge detection and line/contrast guiding without swapping sensors.

## Detailed Answer

Yes. Unlike competitor systems that require separate sensors for edge detection and line/contrast guiding, a single [Roll-2-Roll® Sensor](https://r2r.tech/products/sensors) handles both functions. The same infrared sensor that detects physical material edges can also detect printed lines, coating edges, and contrast patterns. This dual capability reduces equipment cost and simplifies changeovers—operators don't need to swap sensors when switching between edge-guided and line-guided products.
