The LD46 series luminescence sensors line is ideal in applications, such as pharmaceutical, woodworking, automatic packaging and mechanical industries, where ultraviolet light can be emitted and receive visible light reflected from luminescent surfaces. The technology in this sensor allows the detection of fluorescent marks on any object separately from its color, material and distance inside the operating range. The LD46 avoids interferences or reflections from non-luminescent surfaces, like mirrors, glass, shiny metal surfaces, etc.
