Erwin Sick Ltd introduces the LUT series of luminescence sensors, able to detect fluorescent materials or markings on any type of product. They are particularly useful in situations where lack of contrast or inconsistency in the colour, pattern or surface of the product make life difficult for standard optical sensors or contrast scanners (see Plate 7).
If the product is not naturally fluorescent, marking agents can easily be added to printing inks or varnishes. Although invisible to the human eye, these can be reliably detected by the LUT and the resulting signal used for a variety of sorting and positioning tasks. Erwin Sick is able to supply a list of companies that can provide them.

The LUT series of liminescence sensors
Housed in a robust die-cast metal housing and protected to IP65, the LUT units have solid state LED light sources and interchangeable lenses to allow scanning distances from 10 to 90mm. A high switching frequency of 1500Hz permits fast machine cycle times. There is an adjustable time delay and outputs can be analogue, PNP or NPN switching.
Typical applications include the alignment of cans on a filling line, label detection, missing part detection on an assembly line for mechanical components, circular saw control and product sorting. LUT luminescent sensors offer elegant solutions to a variety of sensing requirements in the printing, packaging, pharmaceutical and other manufacturing industries and are a welcome addition to the growing range of sensing solutions from Erwin Sick.
