## Question

Do I need a motorized sensor to find and track the line position?

## Short Answer

No. Wide sensing ranges (48-960 mm) let the sensor see the entire area without mechanical movement.

## Detailed Answer

No. Traditional line sensors have narrow fields of view, requiring motorized positioning to physically move the sensor until it finds the line. [Roll-2-Roll® Sensors](https://r2r.tech/products/sensors) have wide sensing ranges from 48 mm to 960 mm, allowing the sensor to see the entire potential line position area simultaneously. The sensor and controller automatically identify and track the line within this range—no mechanical movement required.
