A specific wavelength of UV light is emitted by luminescence sensors. If the light is directed at a luminescent object, it will reflect back within the visible wavelength range depending on the luminescent material used.
This effect is used by the sensors, for instance, to make markings on labels visible. Regardless of the design, color, or surface characteristics of the fluorescent material or marks on any material, they can be consistently identified.
UV light is emitted by luminescence sensors with a wavelength of about 375 nm.
The global luminescence sensors market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The LUT series of luminescence sensors from Erwin Sick Ltd. can identify fluorescent materials or markings on any kind of product.
They are especially helpful when ordinary optical sensors or contrast scanners struggle to function due to poor contrast or inconsistent color, pattern, or surface of the goods.
Marking agents are simply incorporated into printing inks or varnishes if the product is not intrinsically luminous.
The LUT can accurately detect these even though they are invisible to the human eye, and the generated signal can be used for a number of sorting and positioning tasks. Erwin Sick can provide a list of businesses that can offer them.
The LUT units contain solid state LED light sources and variable lenses to provide scanning distances from 10 to 90mm, and they are protected to IP65 standards in a sturdy die-cast metal body.
1500 Hz switching frequency allows for quick machine cycle times. The time delay can be adjusted, and the outputs can switch in analogue, PNP, or NPN fashion.
Can alignment on a filling line, label identification, missing part detection on an assembly line for mechanical components, circular saw control, and product sorting are examples of typical applications.
LUT luminescent sensors are a welcome addition to the expanding line of sensing products from Erwin Sick and provide elegant solutions to a number of sensing applications in the printing, packaging, pharmaceutical, and other manufacturing industries.
