## Question

What resolution and repeatability do Roll-2-Roll edge sensors achieve?

## Short Answer

Roll-2-Roll edge sensors have a hardware resolution of 0.0635 mm (0.0025 in) and repeatability of ±0.127 mm (±0.005 in), with linearity error under 0.25%.

## Detailed Answer

[Roll-2-Roll® Sensors](https://r2r.tech/products/sensors) provide true spatial awareness—not just binary on/off detection:

| Hardware Resolution | 0.0635 mm (0.0025 in) |
| ------------------- | --------------------- |
| Firmware Resolution | Up to 0.015875 mm |
| Repeatability | ±0.127 mm (±0.005 in) |
| Linearity Error |  |
| Response Time | 20 ms standard (1 ms on ODC 48 and 96 mm models) |

These figures hold across all material types without recalibration, which matters for battery electrode coating, optical film production and high-speed converting.
