Magnetic sensor MSAC501
Absolute, high-resolution position acquisition for rotative applications
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. Circumferential speeds of 25 m/sec (incremental) or 5 m/sec (absolute) can be attained.
