position, angle an encoder is the ideal solution when it comes to precise
position detection in industrial automation. The same applies to measuring
revolutions and rpm as well as speed and acceleration. High-resolution optical
encoders and extremely rugged magnetic encoders complement one another
perfectly and permit exact measurements in all kinds of applications. Rotary
encoders are available as incremental and absolute encoders. Wire draw encoders
and linear encoders with a measuring element are available in linear measuring

range is capped off by inclination sensors that enable non-contact detection of
angles in one or two axes.

Incremental encoders

Versatile, compact
and flexible Incremental encoders

encoders generate information about position, angle, and rotation counts. The
resolution is defined in the number of lines or pulses per rotation, which the
encoder transmits to the control unit for each rotation. The current position
can be determined by the control unit by counting these pulses. A reference run
can be necessary when switching on the machine.

Absolute encoders

Flexible, compact and
reliable – absolute encoders made to measure!

encoders generate information about position, angle, and rotation counts in
type-specific angle steps. For this, a unique code pattern is assigned to each
angle increment. The number of code patterns available per revolution
determines the resolution. Each code pattern forms a unique reference, and is
therefore an absolute position. There is therefore no need for a reference run
after switching on. A singleturn encoder measures the absolute position within
a revolution. A multiturn encoder not only provides the position within a
revolution but also the number of revolutions.

Safety encoders

Safety in motion
functional safety encoders

reliable encoders assist in the implementation of safety functions,
facilitating safe and efficient machine operation. This is backed up by SICK’s
many years of safety expertise, an international service and training network,
and a range of optimized system solutions. Functional safety encoders generate
information about position, angle, and revolution counts, with a particular
emphasis on mechanical and electrical safety. By offering these encoders along
with reliable control solutions, SICK can offer all of the various components
required for the implementation of comprehensive safety solutions under one

Wire draw encoders

Wire draw encoders –
made-to-measure solutions for your applications

draw encoders consist of a wire draw mechanism and an encoder. The rotation of
the drum, which is proportional to the length being measured, is recorded and
output by an encoder. This facilitates positioning on linear measuring paths.
SICK’s wire draw encoders support a large selection of interfaces and
facilitate easy system integration for applications in challenging industrial
settings. Different performance classes make it possible to select the ideal
device for the application at hand.

Linear encoders

Measuring with
absolutely no contact – with linear encoders from SICK

encoders detect linear movements as absolute position values without making
contact. No reference run is required for the wear- and maintenance-free
encoders. Different constructions with high resolution and rugged design enable
use in a wide range of applications and industries.

Measuring wheel encoders

measurement of linear movements directly on the measurement surface

wheel systems use a wheel to record linear movements, which they then convert
to speed or position values. These systems do not require a reference point on
the surface to be measured, making them well-suited to measuring a wide range
of surfaces. The integrated spring ensures that the wheel exerts a consistent
pressure on the surface, thereby guaranteeing slip-free measurement.

Inclination sensors

inclination measurement with precision.

sensors take a non-contact measurement of the inclination angle of an object in
relation to the earth’s gravity. Thanks to the use of capacitive MEMS
technology, inclination sensors are both highly precise and extremely reliable.
One-dimensional sensors measure the inclination of an axis to 360 , whereas
two-dimensional sensors are able to measure two axes simultaneously to 90 .
