SICK is rounding out its portfolio with the optical high-resolution SFS/SFM60 motor feedback systems in hollow shaft design. Especially with self- and force-ventilated synchronous motors, this mechanical component meets customer requirements, as do various hollow shafts and high protection classes (IP65). A wide variety of product variants fulfils nearly every requirement. The SFS/SFM60 motor feedback systems use a globally standardized interface.

It provides maximum flexibility and reduces installation times - plug & play at its best. The rugged shaft bearing increases the service life and at the same time reduces the servicing and maintenance requirements. It also achieves optimum concentricity and a previously unattainable low level of vibration even at maximum operating speeds.

HIPERFACE® motor feedback system in singleturn and multiturn design, compatible with the world's leading drive systems
1,024 sine/cosine periods per revolution
Absolute position with a resolution of 32,768 increments per revolution and 4,096 revolutions with the multiturn system
Mechanical flexibility through different blind hollow shaft and through hollow shaft diameters (8 to 15 mm diameter), available with various stator couplings
IP65 protection class
Certified according to SIL2/PL d (only valid for SFS60S/SFM60S...)

Convenient traceability and simple maintenance thanks to storage of motor-specific data in the electronic type label
Large ball bearing distances reduce uneven wear and minimize vibration on the encoder housing, which increases the encoder's service life
The nickel code disk offers a high degree of vibration resistance and an extended temperature range
Shorter development times through standardized mechanical interface
Platform for the future, since all electrical interfaces (TTL/HTL, 1Vpp, SSI, PROFIBUS, HIPERFACE DSL®) are or will be available in this mechanical component.
