The SICK LUT3-951 (Part No. 1019288) is a high-performance luminescence sensor designed to detect fluorescent markings on objects that are invisible under normal lighting conditions. Utilizing a UV LED light source with a wavelength of 375 nm, it excites luminophores on the target surface, causing them to emit visible light. This emitted light is then detected by the sensor, allowing for precise identification and verification of markings.

With a sensing distance of up to 50 mm and a light spot size of 5 mm × 15 mm, the LUT3-951 is ideal for applications requiring high-resolution detection of small or intricate markings. Its adjustable potentiometer allows for fine-tuning of sensitivity, accommodating various types of luminophores and background conditions.

The sensor operates within a supply voltage range of 12 V DC to 30 V DC and consumes less than 60 mA of current, making it energy-efficient and suitable for integration into systems with limited power resources. Its high switching frequency of 1.5 kHz ensures rapid response times, essential for high-speed manufacturing processes.

Designed for versatility, the LUT3-951 offers both PNP and NPN switching outputs, facilitating compatibility with a wide range of control systems. The sensor is equipped with a 5-pin M12 male connector, ensuring secure and reliable electrical connections.

Built to withstand challenging industrial environments, the LUT3-951 features a rugged die-cast zinc housing with an IP67 protection rating, safeguarding it against dust and water ingress. This robust construction ensures long-term durability and reliable performance, even in harsh conditions.

Applications for the LUT3-951 include quality control in packaging lines, verification of labels and markings in the pharmaceutical industry, detection of fluorescent coatings in automotive manufacturing, and monitoring of printed circuit boards (PCBs) for correct placement of components. Its ability to detect fluorescent markings makes it an invaluable tool in industries where precise identification and verification are critical.

In summary, the SICK LUT3-951 (Part No. 1019288) luminescence sensor offers high-resolution detection, rapid response times, versatile output options, and robust construction, making it an excellent choice for applications requiring precise and reliable identification of fluorescent markings.
