product pic

Capable of detecting luminescence in glue marks, labels, plastics, inks, invisible markings, and so on, LRT 440 series of luminescence sensors comes in four models with special filtering for specific ranges of luminescence. Sensor uses a visible blue light LED instead of the conventional incandescent bulb to provide trouble-free operation. The sensor comes in a small, metal housing with glass lens and has an IP67 rating. Filtered versions detect 490 to 750 nm (blue/green), 515 to 750 nm (yellow/green), 565 to 750 nm (orange) and 590 to 750 nm (red).
