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 Ö 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 VSS signals
  • Reading distance ≤1 mm

  • Works with MRAS506 magnetic ring
