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, pitch-
controlled 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 off-
shore operations.
Build on SICK‘s compe-
tence – 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 multi-turn encoder achieves maximum reliability via its magnetic, and thus extre-mely robust, scanning func-
tion. The innovative and
gearless multiturn techno-
logy reduces the number
of moveable parts on the
A3M60 to a minimum. This
results in a longer service
life with reduced mainte-
nance 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 fami-lies 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 imple-mented using mechanical drives – they deliver the revolution information very reliably and free from inter-ference. The principle of operation is such that a sensor scans permanent magnetic elements

arranged on a magnetic

precision possible due to
the high base resolution of
8,192 steps per revolution.
