About AKM
Rotation Angle Sensors
The AKM rotation angle sensor enables the measurement of magnetic fields in parallel to the chip surface and can detect the absolute angle of a magnetic field.
Products
AKM has the rotation angle sensor by applying magnet sensing and signal processing technologies developed in Hall Effect ICs and Electronic compass.
It can be used for industrial equipmentsuch as BLDC motors, stepper motors, robots, and actuators. Our products contribute to the following user benefits.
AKM provides benefit to end-users with new experience and value
- Usable in bad environments
- High-accuracy even in case of misalignment
- Improvement of accuracy by angle error calibration function
- Available for hollow shaft motor (Off-Axis configuration)
- No need for zero return operation by absolute angle detection
