The Sick LUT9U-11336 luminescence sensor (part number 1047054) is a high-performance device specifically designed for the detection of fluorescent and luminescent markings that cannot be reliably identified by standard optical sensors. By employing a UV-LED light source operating near 375 nm, the sensor activates luminescent properties on a target surface, allowing accurate detection even when the markings are invisible to the human eye or hidden under visible printing and coatings.

What sets this model apart is its extended detection range of up to 120 mm, providing increased installation flexibility compared to shorter-range variants. This allows the sensor to be mounted at greater distances from the target, which can be advantageous in applications where space constraints, conveyor movement, or safety considerations require more clearance. Despite its longer range, the LUT9U-11336 maintains a defined and focused light spot, ensuring that detection remains precise and consistent.

The device is equipped with dual NPN/PNP output options, enabling easy integration into both new and existing automation systems. Operating in Light-ON mode, the outputs are activated when luminescence is detected, ensuring simple and intuitive functionality. This adaptability helps engineers and system designers reduce complexity during installation and eliminates the need for additional converters or relays.

Durability is a hallmark of the LUT9U-11336. Its IP67-rated housing provides complete protection against dust and resistance to temporary water exposure, making it suitable for challenging environments such as packaging lines, bottling plants, or electronics manufacturing facilities. The 5-pin M12 male connector ensures secure wiring and dependable connectivity, while also simplifying replacement or maintenance.

Practical applications for this sensor are broad and diverse. In packaging and labeling, it verifies the presence of invisible fluorescent security marks, ensuring product authenticity and traceability. In pharmaceutical production, it confirms the application of luminescent codes on medicine containers, reducing the risk of errors in distribution. In automotive and electronics industries, it detects UV-sensitive adhesives, coatings, or alignment marks that are critical for assembly accuracy. With a fast response time between 75 µs and 1 ms, the LUT9U-11336 supports high-speed production environments without compromising detection reliability.

In summary, the Sick LUT9U-11336 combines longer sensing distance, precision UV detection, versatile output options, and robust environmental protection into a compact and reliable sensor solution. It is engineered for industries where invisible markings play an essential role in product verification, quality control, and safety. By offering extended range and dependable performance, this sensor not only enhances operational reliability but also provides manufacturers with greater flexibility in system design and installation.
