Luminescence Sensors
Oct 2009
SICK Inc.Request Info
MINNEAPOLIS, Oct. 26, 2009 – Sick Inc. has launched two new luminescence sensors. The LUT8 and LUT9 react to luminescent pigments that are activated by a UV light source in the sensor. These cost-competitive, high-performance devices provide longer sensing ranges and more selection models than previous versions. The LUT9 offers additional advancements, including selectable dual light ports, IO-Link for remote monitoring and for easy setting of the mark and the background.

The sensors detect fluorescent materials or marks, irrespective of pattern, color or surface texture, on almost any substrate. Interchangeable lenses enable various scanning distances to be selected without exchanging the sensor, and filters suppress any background luminescence. The rotary selection switch adjusts sensitivity across eight levels, from low to high.
Supply voltage is from 12 to 30 VDC. The light source is a UV LED at 375 nm. Power consumption is <100 mA, maximum ripple is 5 V, output current is 100 mA, and analog output is from 0 to 13 mA. Scanning distance is up to 250 mm.

The sensors are suitable for use in applications requiring high-accuracy luminescent mark detection in the packaging, food and beverage, automotive, lumber, pharmaceutical, print, postal and general manufacturing markets. They offer wavelength adjustments to easily identify difficult-to-detect luminescence characteristics, particularly luminescent marks in recycled materials. Different light spot patterns and a high visibility bar-graph display, which illuminates when the higher luminescence intensity is detected, provide increased installation flexibility.

LUT9 versions with IO-Link capabilities provide continuous monitoring adjustments to process parameters, enabling simple, cost-effective diagnostics, even from remote locations.
