LD46 Luminescence Sensor - DATALOGIC

LD46 Luminescence Sensor - DATALOGIC

The LD46 series from DATALOGIC represents a high-performance solution for luminescence detection in industrial automation. These sensors operate by emitting ultraviolet (UV) light and detecting only the visible light converted and reflected from fluorescent objects or marks, ensuring reliable operation independent of background color or surface texture. Key technical specifications include an operating distance of up to 100 mm and a switching frequency of 2 kHz, achieved through high-power UV emission using six LEDs. The high power and definition of the light spot allow detection of critical targets with poor, non-homogeneous, or discontinued luminescent levels, such as on raw wood, corrugated cardboard, fabric, or ceramic tiles. The sensor features a teach-in push-button and bar graph indicator for fast and easy setup, along with a rotatable M12 5-pole connector for mechanical adaptability.

These sensors are primarily applied in packaging lines, woodworking machines, glass processing equipment, and ceramics manufacturing machinery. They are ideal for environments requiring precise detection of fluorescent markings or labels on moving surfaces, where background interference must be eliminated.

The main subcategories include the LD46 series with various models differentiated by sensing range and output type. Common article codes follow a pattern like LD46xxxx, where xxxx denotes specific variants such as NPN or PNP outputs, cable or connector versions, and light-on or dark-on configurations. For example, the LD46-100-NPN model offers a 100 mm range with NPN output.
