Available. The Keyence CZ-H52 is a reflective sensor head designed for fluorescence detection using ultraviolet (UV) light. It is part of the CZ-V20 series of digital RGB sensors, ideal for applications requiring the detection of fluorescent materials and paints. The sensor emits UV light at a wavelength of 375 nm and detects the reflected light converted into visible light by fluorescent substances. This capability allows for the detection of various fluorescent targets, including labels, inks, dyes, and coatings. The CZ-H52 features a detection range from 25 to 55 mm, with a recommended distance of 35 mm, and a minimum spot diameter of approximately 10 mm at a reference distance of 25 mm. The sensor operates within an ambient temperature range of -10 to +55°C and has an enclosure rating of IP40, ensuring durability in various industrial environments. Its compact design, with a weight of approximately 40 g, makes it suitable for integration into space-constrained applications.
