products and are now acknowledged as being one of the leading ‘one-stopshops’ for most process to packaging applications. A good example of this is their new range of OC50 / OC60 Contrast and Luminescence Sensors which provide reliable and precise detection of minute and invisible print marks even at very fast speeds thanks to low jitter>7µs. ‘Jitter’ is best described as any deviation in, or displacement of the

The OC60 is offered for higher performance contrast sensing for lower Jitter measurements of >7 µs using the same RGB LED single lens optics as the OC50 although with glass lenses, static and dynamic teach-in within a metal housing. Optical lenses for this option are available for distance up to 40mm. The OC60 also has an adjustable cable outlet in 5 positions along with industry

maximum positioning flexibility. The OC60 luminescence sensing option features UV LED single lens optics, glass lenses and is designed for effective detection of fluorescent markings and can be adjusted for 5 sensitivity levels. It provides very quick response times of 0.34 ms and is available with optical lenses for distances up to 50mm. The OC60D has a colour mode to detect not only the contrast but also the actual colour so is particularly suitable for colour detecting and sorting applications, such as those required for packaging in the food and drink processing industries.
