Magnetic sensor MSAC200

Absolute rotation with flexCoder technology

open expert video
With flexCoder technology, the MSAC200 can be flexibly adapted to the customer's design and provides precise absolute values with high installation tolerances at the same time. It is basically possible to adapt the encoder and the magnetic ring for precise fitting, for example in motors. An additional feature is the high reading distance ≤0.6 mm and axial tolerance of ±0.5 mm to facilitate the design of the overall system and enable use in dynamic applications.

Profile MSAC200:

  • Magnetic absolute encoder single-turn
  • Integration into small installation space possible
  • Absolute resolution up to 20 Bit
  • Repeatability 0.01°
  • Reading distance ≤0.6 mm
  • Interface BiSS C, SSI
  • Optionally analog Sin/Cos 1 Vss or digital line driver
  • Industrial and medical applications e.g., motor feedback, handling automation and robotics
  • Industry 4.0 ready

Industry 4.0
In most cases, data exchange with the magnetic encoders is limited to the exchange of process data. In addition to the process data, intelligent drives provide additional information that can be evaluated for condition monitoring up to predictive maintenance:
