High-speed SICK LUT3-952 luminescence sensor with UV LED for precise mark detection in packaging, labeling, and quality control applications.
The SICK LUT3-952 is a high-performance luminescence sensor designed for fast and reliable detection of UV-visible marks, labels, and adhesives, even on challenging surfaces. With a sensing distance of up to 50 mm and a precise UV LED light source (375 nm), it ensures accurate detection in high-speed production environments. Its rugged zinc diecast housing and IP67 protection make it ideal for use in demanding industrial conditions, providing consistent performance in packaging, printing, and labeling applications.
Why?
Because traditional sensors struggle to detect low-contrast marks, invisible adhesives, or clear labels at high speeds, the SICK LUT3-952 uses UV excitation and precise optical filtering to ensure flawless detection—no matter how tricky the surface.
What Problem Does It Solve?
The LUT3-952 solves the challenge of reliably identifying luminescent marks that are invisible to the human eye or conventional sensors. By using a focused UV light source and high-speed signal processing, it eliminates false triggers from background materials, reduces production downtime, and ensures precise product alignment and quality control, even in demanding industrial environments.
