A combination of the MSAC506 magnetic sensor and the MRAC506 magnetic ring forms a system for absolute angle measurement. The MSAC506 sensor has an SSI interface with a resolution of 12 … 16 bit. There is also an analogue output (1 VSS) with 64 periods for dynamic position tracking. The sensor has an LED for distance monitoring

  • Magnetic absolute encoder single-turn
  • Compact design
  • Resolution 12 … 16 bits
  • Additional analog Sin/Cos 1 VSS signals
  • Reading distance ≤1 mm
  • Works with MRAS506 magnetic ring
  • 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:

Actual position -- Plausibility monitoring

Hint for mounting

Please ensure correct allignment of both system components to each other during mounting of sensor and magnetic ring.

A, Sensor/ring reading distance
     (active measurement area)		 0.1 … 1.0 mm
B, Lateral offset ±1.5 mm
C, Misalignment <±0.5°
