What is the advantage of Roll-2-Roll® Sensors for center guiding?

Roll-2-Roll® Sensors eliminate the need for mechanical sensor positioners—motorized assemblies that move sensors to chase edge positions. Traditional center guiding requires sensor positioners because narrow sensors cannot see both edges when web width changes. These positioners introduce motors, lead screws, and sliding brackets that jam, wear out, and require maintenance. Roll-2-Roll® Sensors have wide fields of view (48-960 mm) allowing them to track width variations electronically without moving parts, eliminating a major category of mechanical failures and maintenance.
