No. Single wide sensors (up to 960mm) can see both edges. Wide webs may need two sensors.
Not necessarily. Roll-2-Roll offers two approaches: For wide webs with significant width variation, use two sensors mounted on opposite sides. For narrow to medium webs (up to 960 mm), a single wide sensor like the ODC 480, ODC 768, or ODC 960 can see both edges simultaneously. The single-sensor approach simplifies installation (no alignment between sensors required) and works well for label converting, battery electrode, and narrow web applications.

Center guiding averages edge defects, ignores wrinkles, and ensures symmetric margins for coating/laminating.
Center guiding provides three key advantages: First, it naturally averages out edge defects and fuzzy nonwoven edges, resulting in more stable control. Second, it is immune to wrinkles—when a wrinkle narrows the web, center guiding sees the width reduction on both sides and maintains the true centerline. Third, for symmetric processes like coating or laminating, maintaining the centerline ensures equal margins on both sides. Edge guiding would require the web edge to stay perfectly straight, which is challenging with materials like nonwovens.

ODC uses external controller with touchscreen. 1DC has built-in controller for PLC integration. Same accuracy.
Both use the same fiber-optic sensing technology and achieve identical accuracy. The ODC Family requires an external controller (SCU5 or SCU6x) with a touchscreen interface—ideal for end users who want easy setup without programming. The 1DC Series has the controller built-in and connects via EtherNet/IP, PROFINET, EtherCAT, or Modbus/TCP—ideal for OEMs and users who prefer PLC integration. Pricing is similar between the two options.

Roll-2-Roll® Sensors achieve 0.0635mm resolution with >99.9% repeatability on all materials.
Roll-2-Roll® Sensors achieve 0.0635 mm (0.0025 in) hardware resolution with repeatability greater than 99.9%. This precision is maintained 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.

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.
Quick Answer:
Short Answer
Yes, Roll-2-Roll® Sensors detect clear films using infrared light reflection without recalibration.
Yes. Roll-2-Roll® Sensors detect clear films using infrared light reflection. Even transparent materials reflect a small amount of infrared light, which the sensors CMOS line camera and adaptive algorithms can reliably detect. This is a key advantage over ultrasonic sensors, which cannot reliably detect clear films, and traditional infrared sensors that require recalibration for different transparency levels.
Quick Answer:
Short Answer
Roll-2-Roll® Sensors use spatial light filtering that automatically adapts to any material properties.
Roll-2-Roll® Sensors use patented fiber-optic technology with adaptive edge detection algorithms. Unlike ultrasonic sensors that measure sound reflection (affected by material density and porosity) or simple infrared sensors that require threshold adjustment, [rr sesors] use spatial light filtering to detect edges regardless of material properties. The sensor automatically adapts to different reflectivity, transparency, and surface characteristics—whether running clear films, opaque substrates, metallic foils, or porous nonwovens.

0.0635mm resolution with 500 Hz update rate.
WPS (Web Position Sensor) series sensors have a resolution of 0.0635mm with ±0.25mm linearity across the full sensing range. The update rate is 500 Hz, providing fast response for high-speed applications.
Quick Answer:
Short Answer
Up to 500 m/min with ±0.1mm accuracy.
R2R edge guiding systems maintain ±0.1mm accuracy at speeds up to 500 meters per minute (1,640 fpm). With a 500 Hz update rate, the sensors respond fast enough for high-speed converting lines.
Quick Answer:
Short Answer
Yes, R2R sensors work on all materials including clear films without recalibration.
Yes. R2R fiber-optic sensors detect edges on clear films (PET, BOPP, cellophane) as accurately as opaque materials. The light scattering technology responds identically to any material—no special settings or sensors required.
