## Question

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

## Short Answer

Yes. The same sensor family does edge and line/contrast guiding; order the white-light head for most line/contrast work (the light source is fixed at order).

## Detailed Answer

Yes, the same sensor family does both. An infrared head handles edges and high-contrast printed lines; for most line and contrast work, order the white-light head. The light source is fixed at order. 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, with 0.0635 mm resolution and ±0.127 mm repeatability at line speeds up to 760 m/min — 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).
