UV LED EMISSION SENSORS The best solution for luminescent mark detection • High-power UV emission for improved sensitivity • Fast switching frequency and response time • Easy setting and clear bargraph indicator • LD46 SERIES The luminescence sensors emit ultraviolet (UV) light and receive visible light reflected from luminescent surfaces. This technology allows the detection of fluorescent marks (even invisible to the human eye) on any object independently from its material, colour or distance inside the operating range. Moreover, it avoids light interferences or reflections from non-luminescent surfaces, like glass, mirrors, shiny metal surfaces, etc. Luminescence sensors can satisfy many different applications, as for example in pharmaceutical and cosmetic industries to detect labels on glass phials or bottles, or correct medicine packaging, in woodworking and ceramic tiles production to check fluorescent selection marks; in automatic packaging to detect whitened paper or fluorescent glues, in textile industry to identify fluorescent cutting guides or labels; in mechanical industry to verify fluorescent paints, lubricants, gaskets or fittings; in vending machines or cash dispensers to check banknotes and credit cards. The high power and definition of the LD46 sensor light spot enable the detection of critical targets with a very poor or non-homogeneous or discontinued luminescent level, as for example on raw wood, corrugated carton, fabric, ceramic tiles. LUMINESCENCE SENSORS LD46 SERIES SETTING DIMENSIONS The switching threshold setting can be easily made pressing the ‘+’ and ‘-’ push-buttons that increase or descrease the sensitivity level which is visualised on the bargraph indicator. The sensor has a KEYLOCK function that deactivates the keyboard avoiding accidental sensor setting. The keyboard is locked at the sensor powering and can be activated by pressing the SET push-button for 5 seconds until the keylock LED turns on. The keyboard is locked again automatically if not used for 2 minutes.
