  • Availability:
    3 Weeks Lead Time
Highly Accurate Sensors Can Also Be Adaptive

Eliminate calibration. These sensors learn and adapt on the fly!

Roll-2-Roll® Sensors can measure edge position of any material without the need for any setup or calibration. The sensing principle relies on light scattering and spatial filtering properties of fiber optics to accurately determine the web position. The 440 mm sensor head is currently the widest sensor in the Roll-2-Roll® Sensor family that can be used for edge sensing/guiding, contrast position sensing/guiding, line guiding, mark detection, thread detection, simple inspection, etc. The sensor head along with the sensor control unit forms the complete sensing solution.

The patented fiber optic sensing principle enables the plug-and-play sensor technology. The sensor technology adjusts automatically to the physical characteristics of the material and provides an accurate position measurement. The sensor is essentially an affordable vision based sensing system different web sensing applications.
