Motor feedback systems rotary HIPERFACE®

High-resolution motor feedback system in hollow shaft design

Your Benefits

  • 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.


High-resolution motor feedback system in hollow shaft design

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 (IP 65). A wide variety of product variants fulfills 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.
