LDu Luminescence Photoelectric Sensors from DATALOGIC represent a specialized category of photoelectric sensors designed to detect the presence of luminescent marks, labels, or materials by emitting ultraviolet (UV) light and measuring the resulting visible fluorescence. These sensors operate by exciting luminescent substances, which then emit light at a different wavelength, allowing for reliable detection even on transparent, reflective, or high-contrast backgrounds. Key technical specifications include a detection range typically up to 50 mm, a UV LED light source with a wavelength around 365 nm, and response times as fast as 50 µs. They are available in various housing styles, such as cylindrical M18 or rectangular, with options for different output types (PNP, NPN, or analog) and connection methods (cable or M12 connector). The LDu series is known for its high sensitivity and immunity to ambient light, making it ideal for precise detection tasks in industrial automation.
These sensors are primarily used in packaging, printing, and labeling applications where luminescent marks are applied to products or packaging materials. Common sectors include food and beverage, pharmaceuticals, cosmetics, and logistics, where they ensure accurate registration, cut control, and product verification. They are also employed in woodworking and textile industries for detecting glue lines, seals, or security marks. The sensors are typically installed in conveyor systems, packaging machines, and printing presses, often integrated into control cabinets or directly mounted on machinery via brackets.
The LDu series includes several subcategories, such as the LDu-12 series with a compact cylindrical housing and the LDu-50 series with a rectangular housing for longer detection ranges. Key article codes include LDu-12-50-xxxx (where xxxx denotes specific output and connection variants) and LDu-50-100-xxxx. These codes typically follow a pattern: LDu indicates the series, the first number denotes housing type (e.g., 12 for M18 cylindrical), the second number indicates detection range in mm, and the suffix specifies output type (e.g., P for PNP, N for NPN) and connection (e.g., C for cable, M for M12 connector). Accessories like mounting brackets and reflectors are also available but are not the focus here.
