Print Mark Detection for Cutting Lines
Ensures precise recognition of registration marks in high-speed print-and-cut systems, even on reflective or glossy film. The RGB illumination and ultra-fast 10 µs response time prevent misalignment during material cutting.
Print Quality Control in Labeling
Monitors print registration and detects missing or incorrect graphics on product labels. The RGB color mode adapts to varied print hues, while advanced optics handle uneven or textured surfaces with high accuracy.
Splice Detection in Web Processing
Detects splices or changes in paper, film, or foil during converting operations. The high switching frequency and dynamic teach-in adapt to material flutter and variations without false triggers.
Positioning Tubes in Manufacturing
Accurately aligns tubes or cylindrical parts on conveyor systems using a fine 0.9 × 3.8 mm light spot and versatile teach-in modes, improving positioning and assembly precision.
Bottle Label Alignment in Packaging Lines
Verifies correct label placement on bottles and identifies misalignments in high-speed packaging processes. The RGB LED and fast jitter control maintain consistent accuracy.
Roll-End Detection in Web Winding
Identifies end-of-roll marks or tags during winding operations. The high-speed detection prevents unexpected material run-outs and production stoppages.
Color Control in Yarn or Cable Production
Detects color changes or splice boundaries during high-speed production of yarn, cables, or textiles. Maintains consistent detection despite rapid movement and varying surface colors.
Print Control in the Printing Industry
Maintains registration accuracy and monitors print consistency across labels, packaging, and other printed materials. The sensor’s high grayscale resolution and color flexibility allow it to adapt to different designs and substrates.
