With a defined sensing distance of 20 mm and a receiving range of 450–750 nm, it is optimized for identifying fluorescent labels, adhesives, and contrast agents on various surfaces. The device outputs via PNP/NPN switching and operates at a high 1.5 kHz switching frequency, ensuring rapid response in dynamic automation processes. Its optical system includes KV 418 filters for stable signal reception, while the manual potentiometer adjustment allows fine-tuning for application-specific sensitivity. Housed in a robust die-cast zinc body, it features IP67 protection and a 5-pin M12 connector, making it both rugged and simple to integrate into industrial systems. Key Features: Ultraviolet LED Light Source: Uses 375 nm UV light to excite luminescent materials invisible to the human eye, enabling precise detection of special inks, adhesives, or coatings. Targeted Sensing and Filtering: Receives reflected signals in the 450–750 nm range using KV 418 filters and forms a narrow elliptical light spot (3 x 9 mm) for concentrated sensing on small areas. Fast 1.5 kHz Switching Frequency: Suitable for high-speed production lines where accurate detection and fast response are critical to minimize false reads and maximize throughput. Versatile Output and Tuning: Equipped with PNP/NPN output configuration and adjustable sensitivity via built-in potentiometer for application-specific adaptation. Industrial-Grade Construction: Compact die-cast zinc housing, IP67 enclosure rating, and M12 5-pin connector ensure mechanical durability and reliable installation in harsh environments. The LUT3-920 provides high-precision, fast-response luminescence detection with robust filtering, making it ideal for detecting invisible markers in packaging, labeling, and automation.
