4. Knowing
which way the wind is blowing.
Wind power systems must
operate at near 100 %
availability – hence quality
and reliability are extremely
important.
Variable-speed, pitchcontrolled systems are the
current state-of-the-art
in wind energy system
construction. They can be
efficiently deployed in the
harsh conditions prevalent
in both onshore and offshore operations.
Build on SICK‘s competence – a competence
demonstrated by over
ten years’ experience in
this sector and more than
20,000 encoders installed
in pitch-controlled systems.
Absolute encoder A3M60
– built to last.
The A3M60 is an extremely
robust absolute multiturn
encoder in a 60 mm
housing. Even under the
harshest environmental
conditions both onshore
and offshore, the multiturn encoder achieves
maximum reliability via its
magnetic, and thus extre4

mely robust, scanning function. The innovative and
gearless multiturn technology reduces the number
of moveable parts on the
A3M60 to a minimum. This
results in a longer service
life with reduced maintenance requirements.
Absolute encoder AFM60
– the wonder of precision.
With 30-bit resolution and
a high level of robustness,
the new absolute multiturn
encoder AFM60 sets a new
record. Even its little brother
– the absolute singleturn
encoder AFS60 – impressive
due to its high 18-bit
resolution, counts as one
of the best products in its

market segment. The single
resolution, as well as the
zero point or offset are
programmable.
The two new product families are especially suitable
for application in the harsh
conditions prevalent in wind
power systems – in other
words, when the highest
levels of accuracy and
availability are called for.

Absolute encoder ATM60
– the classic design.
The absolute multiturn
encoders ATM60 are implemented using mechanical
drives – they deliver the
revolution information very
reliably and free from interference. The principle of
operation is such that a
sensor scans permanent
magnetic elements
arranged on a magnetic
scale. This makes high
precision possible due to
the high base resolution of
8,192 steps per revolution.

6. Extremely robust
and extremely precise.
incremental encoder
dFs60 – the rotary design.
incremental encoder
dgs35 – the robust design.
The DFS60 is a high-resolution incremental encoder
in a 60 mm design. The
DFS60 is unique in its class
with a maximum number
of lines as high as 65,536.
Excellent concentricity and
exceptional robustness
are achieved thanks to the
large distance between
the ball bearings which
support the encoder shaft.
The DFS60 is therefore predestined for application in
wind power systems.
The incremental encoders
DGS35 are used in the
harshest conditions across
the globe. The stable design
with an enclosure rating
of up to IP 66 ensures for
a robust but nevertheless
high-resolution incremental
encoder. Equipped with a
through hollow shaft with
a maximum diameter of
30 mm, the DGS family is
suitable for use in every
application.
Motor feedback systems
sFs60, sFM60 with
HipErFACE® interface.
HIPERFACE® motor feedback systems comprise a
combination of incremental and absolute encoders,
successfully uniting the
advantages of both encoder types. They are particularly suited for absolute
position finding, with the
number of steps being
32,768 per revolution and
with a maximum of 4,096
revolutions – that gives
