Quick Answer:
No. Single wide sensors can see both edges up to their sensing range minus 20 mm (940 mm on a 960). Wider 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, a single wide sensor like the ODC 480, ODC 768, or ODC 960 can see both edges simultaneously: up to 460 mm on a 480, 748 mm on a 768, or 940 mm on a 960 (sensing range minus 20 mm of edge allowance). The single-sensor approach simplifies installation (no alignment between sensors required) and works well for label converting, battery electrode, and narrow web applications.
Quick Answer:
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.
Quick Answer:
ODC uses external controller with touchscreen. 1DC has built-in controller for PLC integration. Same repeatability.
Both use the same fiber-optic sensing technology and achieve identical repeatability. 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.
Quick Answer:
Roll-2-Roll® Sensors achieve 0.0635 mm (0.0025 in) resolution with ±0.127 mm (±0.005 in) repeatability on all materials.
Roll-2-Roll® Sensors achieve 0.0635 mm (0.0025 in) hardware resolution with ±0.127 mm (±0.005 in) repeatability, and hold it 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.
Quick 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:
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 sensor's CMOS line camera captures and the controller's adaptive edge detection picks out. This is an advantage over ultrasonic sensors, whose readings shift with temperature and which can't work in vacuum, and over infrared sensors that typically need recalibration for different films.
Quick 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 fiber array captures scattered light from any material, and the controller's adaptive edge-detection algorithm adjusts to its reflectivity and transparency, so no recalibration is needed—whether running clear films, opaque substrates, metallic foils, or porous nonwovens.
Quick Answer:
0.127 mm resolution (legacy); sensing ranges 48–900 mm.
WPS (Web Position Sensor) series sensors (legacy) have 0.127 mm resolution and sensing ranges of 48, 112, 221, 440 and 900 mm.
Quick Answer:
Up to 760 m/min (2,500 fpm) with ±0.127 mm repeatability.
Roll-2-Roll edge guiding systems maintain 0.0635 mm (0.0025 in) sensor resolution and ±0.127 mm (±0.005 in) repeatability at line speeds up to 760 m/min (2,500 fpm). With a 500 Hz update rate, the sensors respond fast enough for high-speed converting lines.
Quick Answer:
Yes, Roll-2-Roll sensors work on all materials including clear films without recalibration.
Yes. Roll-2-Roll fiber-optic sensors detect edges on clear films (PET, BOPP, cellophane) with the same resolution and repeatability as opaque materials. The light scattering technology responds identically to any material—no special settings or sensors required.
