Quick Answer:
Short Answer
Roll-2-Roll sensors range from 48-960mm. Choose based on web wander plus safety margin.
Roll-2-Roll offers sensing ranges from 48 mm to 960 mm (1.9 in to 38 in). For edge guiding, the sensing range should accommodate your maximum expected web wander plus a safety margin. Wider sensing ranges also allow handling multiple web widths without repositioning the sensor—for example, a 960 mm sensor can track webs from narrow labels to wide films without adjustment, eliminating changeover time and operator errors.
