Magnetic sensor MSAC506

Absolute-rotative, SSI interface, resolution max. 16 bits

open expert video

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.

Profile MSAC506:

Magnetic absolute encoder single-turn
Compact design
Resolution 12 … 16 bits
Additional analog Sin/Cos 1 V_SS 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:
