## 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.

## About Roll-2-Roll Technologies

Roll-2-Roll Technologies designs and manufactures patented fiber-optic web position sensors and advanced web guiding controllers — the precision measurement and control core of modern roll-to-roll manufacturing. Spun out of Oklahoma State University's Web Handling Research Center and trusted by Fortune 500 medical, battery, and nonwovens manufacturers, our patented sensors work without recalibration at ±0.1mm accuracy up to 760 mpm — typical customer outcomes are 50%+ less downtime and payback under six months. Headquartered in Stillwater, Oklahoma, our team of PhDs, controls engineers, and industry veterans extends the sensor + controller core into complete web guide systems including stepper-motor-based linear actuators (RLA, BLA, LHS).
