Contrast Sensor integrates bar graph display.

SICK, Inc. Jun 18, 2004

Press Release Summary:

Model KT5 learns both mark and background via 2-point teach-in process whereby, depending on contrast, optimum transmission color of 3-color LED is activated by sensor and switching threshold is set. Users can detect reflectivity, read set switching threshold from device, assess predicted detection reliability, and if necessary, carry out manual switching threshold adaptation. Model KT5 offers sensing distances of 10, 20, and 40 mm.

SICK Introduces the KT5 Contrast Sensor with added Bar Graph Display

SICK, the global leader in factory and process automation solutions, today announced its new KT 5 Contrast Sensor with bar graph display. Augmenting its existing line of technologically advanced contrast sensors, now the improved KT5 offers additional user-friendly features by integrating a bar display and unique threshold adjustments. These new features enable users to easily inspect and adjust various parameters in the field.

The advanced SICK KT5 offers superior optics, a wide variety of teach-in options and unique automatic selection of the three-color LED light source.

Contrast sensors are integral components of many automated production processes in the packaging industry. They are mainly used in packaging machines for the detection of printed or control marks. The sensor learns both the mark and its background via a two-point teach-in process whereby, depending on the contrast, the optimum transmission color of the three-color LED is activated by the sensor and the switching threshold is set.

With the new KT 5, users can now detect reflectivity, read the set switching threshold from the device, assess the predicted detection reliability and, if necessary, carry out a manual switching threshold adaptation.

If, for example, the appearance of a label changes (and thus the gray-scale value of the mark and background or even the gloss level) the KT 5 can now easily be readjusted during the process.

Features include:
o Sensing distances of 10 mm, 20 mm and 40 mm
o Three-color LED technology
o High-speed switching frequency of 10 kHz
o Automatic switching threshold adaptation for highly reflective materials

Typical applications for the KT5 include: controlling packaging processes, positioning labels, positioning cans and tubes, checking expiration dates, detecting codes, and more.
