Technical Description working principle LD20 based emission visible light when luminescent material struck ultraviolet light. light from LD20 strikes luminescent object mark, ultraviolet light wavelength converted onto visible light reflection detected receiver LD20 through special filter through which only visible light from wavelength passes. Other objects, even highly reflective items, such mirrors, glass chromiumplated surfaces, will convert light into visible light therefore detected. LD20 indicator completely insensitive reflection from shiny objects ambient light. range LD20 ultraviolet detectors specifically designed detect both visible invisible luminescent substances, reflected chalk marks, glue, ink, paint liquid types material such wood, metal, ceramic, plastic, paper. typical application LD20 detection labels bottles, vials cans. LD20 reader easy mount install, rugged metal housing (IP65) makes suitable various fields industrial automation. Features emission 18mm (0.71 (1.6 opeerating distance switching frequency response time Amphenol connector version: dual output analog output connector version: output Adjustable sensitivity output indicator Green exhausted lamp indicator Metal housing IP65 Fiber-optic cables available

Technical Description Optical sensors usually detect target desired target features themselves. When this isn't possible, markings applied object these detected sensor. what when can't apply visible markings object? Very simple: Apply invisible markings! does that work? so-called fluorescent materials (contained special chalks, inks, paints, etc.), which only visible ultraviolet (UV) light. fluorescent materials change invisible light (shortwavelength, here into visible light (between blue dark nm). This effect called photo-synthesis. visible light then detected usual receiver portion sensor. Luminescent sensors especially designed this purpose. Balluff Luminescence Sensor (LDµ) equipped with modern source UV-LED), that external lamp required. Signal processing microprocessor-controlled using teach-in. pressing button learns difference between fluorescent marking background. difference slight reliably detectable, flashing indicates this condition. lens produces sensing distance typically 18mm. 18mm lens increases sensing distance 15.30mm. Configuring internal switches allows turn-off delay disable buttons. PNP/NPN output also selectable. analog signal proportional light reflected marking rounds functionality LDµ. Features source: LED, 100,000 hour life High power available Sensing distance 9.18mm (15.30 with optional lens) Push-button setting Automatic setting lighton/dark-on Time delay setting selectable Analog output standard Configurable connector positions) Button disable Metal housing Fiber optic cable available
