Magnetic sensor MSAC501

Absolute, high-resolution position acquisition for rotative applications

SIKO Global, Magnetic sensor MSAC501
SIKO Global, Magnetic sensor MSAC501
SIKO Global, Magnetic sensor MSAC501
SIKO Global, Magnetic sensor MSAC501
The MSAC501 magnetic sensor serves truly absolute roto measurement, e.g., on large 3-phase current or torque motors.The sensor has the standardized SSI or 485 interfaces. Optionally, an LD output can be selected for incremental signal output.Circumferentialspeeds of 25 m/sec (incremental) or 5 m/sec (absolute) can be attained.
  • Max. resolution 0.0014° (MRAC501) or 4.88 µm
  • Repeat accuracy of 0.0014° (MRAC501) or 4.88 µm
  • System accuracy ±0.06° (MRAC501) or ±0.03 mm
  • SSI output circuit, RS485 (absolute), optional LD (incremental)
  • Signal period 5 mm
  • Status LEDs for diagnosis
