Request InfoKeyence Corp.The CZ-H52 from Keyence Corp. of America is a digital fiber optic UV sensor that detects fluorescent agents used in products and packaging materials. These include labels on plastic, metal and glass containers, tamper-evident packaging, protective coatings on soft drink and medicine containers, dyes, fluorescent paints and clear adhesives. An ultraviolet beam is emitted from the transmitter in the sensor head, and the receiver picks up the visible light reflected by fluorescent materials. Performance is not affected by background patterns or colors, and a sputtered gold coating on the...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra March 2023 IssueSensor HeadThe S mart 2 integrable sensor head from Sensofar features a reduced head width of 90 mm, fitting a 19-in. rack.
