The Sick LUT9B-11626 luminescence sensor (part number 1047056) is designed to detect luminescent or fluorescent materials with a high degree of precision and reliability. Using a UV-LED emitter operating at approximately 375 nm, the sensor excites luminescent properties on surfaces that are not visible under normal lighting. This makes it an indispensable tool for industries that rely on hidden or fluorescent markings for product tracking, quality assurance, and authentication.

The LUT9B-11626 offers a detection range of up to 90 mm, making it suitable for applications where moderate sensing distances are required. Its precisely focused light spot allows it to isolate and detect specific luminescent marks or adhesives without being influenced by surrounding surfaces. This precision ensures consistent performance in fast-moving production environments or systems where accuracy is critical.

With its dual NPN/PNP switching outputs, the sensor provides integration flexibility for a wide range of automation systems. Operating in Light-ON mode, the device activates its output whenever a luminescent signal is detected, allowing for straightforward integration into control circuits, PLCs, or automated inspection equipment. This dual-output design eliminates compatibility concerns, reducing installation time and cost.

Durability is another hallmark of the LUT9B-11626. Its IP67-rated housing offers full protection against dust and resistance to water ingress, ensuring reliable operation in harsh environments such as packaging facilities, bottling plants, or electronics manufacturing lines. In addition, the 5-pin M12 connector provides secure and stable connectivity, ensuring long-term performance while simplifying maintenance or replacement when required.

Applications for this sensor are broad and versatile. In the packaging industry, it ensures the presence of invisible luminescent marks that confirm authenticity, traceability, or correct labeling. In pharmaceutical production, it verifies luminescent codes on bottles, vials, or blister packs, enhancing compliance and reducing the risk of errors. In electronics and automotive assembly, it identifies UV-sensitive adhesives, coatings, or alignment marks that are crucial for quality control and proper assembly. Thanks to its fast response times, typically ranging between 75 microseconds and 1 millisecond, the sensor performs reliably even in high-speed production environments.
