The Sick LUT9U-11306 (Part no. 1046712) is a high-performance luminescence sensor engineered for industrial applications where standard optical sensors cannot deliver reliable detection. By emitting ultraviolet light and detecting the resulting luminescence, this sensor identifies invisible fluorescent or phosphorescent marks that are commonly used for quality assurance, labeling, packaging, or production monitoring.

Built with advanced UV LED technology, the LUT9U-11306 provides stable and precise detection of a wide variety of materials. These include luminescent adhesives, tamper-proof labels, special inks, coatings, and registration marks. Its versatility allows it to be used in industries such as pharmaceuticals, printing, food and beverage, and logistics, where invisible identification or position referencing is critical to production accuracy.

One of the defining strengths of this sensor is its extended sensing range. The LUT9U-11306 can detect luminescent marks from 30 mm up to 200 mm, with adjustable sensitivity to match the application requirements. Whether the marks are faint or highly fluorescent, the sensor can be finely tuned to ensure reliable detection. This makes it suitable for both close-range detection tasks, such as adhesive bead monitoring, and longer-range applications like label positioning in high-speed packaging machines.

The sensor is also designed for durability and reliability in demanding environments. Its IP67-rated housing provides protection against dust and water ingress, ensuring consistent operation even in harsh production conditions. This robust design not only extends service life but also minimizes downtime and maintenance needs.

From a performance perspective, the LUT9U-11306 delivers fast and flexible switching outputs, supporting both PNP and NPN configurations for seamless integration into different control systems. Its rapid response time, down to microseconds, enables accurate detection of luminescent marks on fast-moving materials. This makes it particularly valuable in high-speed production lines where precision timing is essential.

Ease of use is another key feature of this sensor. With its straightforward teach-in setup, operators can quickly configure the LUT9U-11306 to match specific materials and applications. Once set up, the sensor automatically compensates for variations in background conditions or material properties, maintaining stable performance without frequent recalibration.

Compact and lightweight, the sensor is easy to mount in tight machine layouts. It operates on a 10–30 V DC power supply with low current consumption, combining efficiency with reliable performance.
