Registration sensors from SICK
The variety of tasks in
automated production processes today, such as in packaging and printing
machines, require sensors with the highest performance standards. Typical
applications are the detection of visible and non-visible marks, labels and
colors at high speeds as well as the detection of small parts and precise
positioning. SICK offers a wide range of contrast, markless, color,
luminescence, fork and array sensors to solve this wide spectrum of demanding
SICK The pioneer in
contrast sensors for more than 60 years
Contrast sensors are primarily used in packaging/printing machines for the
detection of printed or control marks. SICK’s line of KT contrast sensors
detects even the smallest contrasts at the highest speeds, such as print marks
on foils or packaging. They detect minute grayscale variations between the mark
and the background on matte, shiny or transparent surfaces. A variety of device
types with different contrast resolution methods and teach-in versions are
available to meet wide-ranging requirements.
Focus on color
Color sensors detect the color of a surface. The sensors cast light (red,
green, and blue LEDs) on the objects to be tested, calculate the chromaticity
coordinates from the reflected radiation and compare them with previously
stored reference colors. If the color values are within the set tolerance
range, a switching output is activated.
The bright idea for
Luminescence sensors detect visible and non-visible marks that illuminate
when using ultraviolet (UV) light. Fluorescent material and marks are reliably
detected independently of their pattern, colors or surface conditions on any
material. Luminescence sensors emit UV light with a wave length of
approximately 375 nm. Fluorescent substances convert the UV light into
long-wave visible light, which is then received and evaluated by the
Gloss and performance
The Glare sensor detects and distinguishes glare on even surfaces. It also
provides maximum reliability and saves costs. Previously, gloss on object
surfaces was a disruptive factor that regularly had engineers breaking into a
Now, gloss properties are a distinguishing criterion for process control
regardless of color, transparency or pattern. And it will be engineers eyes
that shine, not their brows. Equipped with intelligent Delta-S-Technology,
Glare is a further milestone in customer-oriented sensor development. Once
again, SICK is confirming its leading position in opto-electronic sensors for
the detection of a range of objects.
and precision combined in a single fork sensor.
SICK fork sensors combine senders and receivers in a single housing,
meaning that they can be adjusted quickly. Thanks to the precise, focused light
beam and the high detection accuracy, the sensors also detect very minor light attenuation
differences. Many different fork sizes, straightforward mounting, and
exceptionally high ambient light immunity are just some of the advantages of
these fork sensors.
Register control does
the work in tough print mark applications
The register sensor line complements our wide range of contrast sensors. As
specialists in the register control of printing presses they offer an optimal
solution to detect marks in tough print conditions with extremely low contrast,
complex colorful printouts or at very high speeds. Our range of register
sensors also includes an ATEX certified fiber-optic product, ensuring safe
solutions in hazardous areas (e.g. when using solvent based ink).
Ax20 array sensors for
edge and diameter detection solutions
Array sensors use closely spaced beams of light to detect even the
slightest differences in gray scale between the target and the background
within their field-of-view. They are ideal for edge and diameter detection as
well as detecting widths and gaps. SICK array sensors offer industry-leading
reproducibility, in addition to compact, rugged metal housings for use in
highly restricted or harsh environments.
From pattern detection
to rapid position identification
The pattern sensor is a proximity-scanning opto-electronic sensor.
Distinctive patterns in an image are used as a reference for the subsequent,
accurate detection and positioning of objects. A stable switching signal is
generated at high speeds with an intelligent algorithm for signal processing
regardless of reference marks. It is typically used in the packaging industry.
