## Question

What resolution and repeatability do Roll-2-Roll® Sensors achieve?

## Short Answer

Roll-2-Roll® Sensors achieve 0.0635 mm (0.0025 in) resolution with ±0.127 mm (±0.005 in) repeatability on all materials.

## Detailed Answer

[Roll-2-Roll® Sensors](https://r2r.tech/products/sensors) achieve 0.0635 mm (0.0025 in) hardware resolution with ±0.127 mm (±0.005 in) repeatability, and hold it across all material types without recalibration. For comparison, this resolution is approximately the thickness of a human hair. The sensors also feature linearity error of less than 0.25% across the full sensing range.
