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.
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
AKM has created rotation angle sensors based on its Hall sensor technology accumulated over 30 years, and has continued to improve their performance to this day. Here, we will explain why AKM's rotation angle sensors are chosen.
Basic Knowledge of Encoder
This is a series of easy-to-understand technical explanations on the types, principles, mechanisms, and features of various encoders.
AKM proposes solutions using its rotation angle sensors that can solve various issues related to rotational detection.
This is a story that clearly explains the features of angle sensors through a conversation between a salesperson and his boss.
How to use rotation angle sensors
High accuracy rotation angle sensor that supports Shaft-End and Off-Axis configuration
The AK7455 is a magnetic 14-bit absolute rotation angle sensor consisting of a Hall element formed on a silicon chip and a signal processing circuit.
By extending and optimizing the bandwidth setting of the angle calculation circuit, we have achieved improved responsiveness during motor acceleration and deceleration that can withstand the control of stepping motors.
This sensor can be used with a very simple configuration of a small magnet and an IC, making it easy to realize a non-contact magnetic encoder for consumer and industrial applications.
Please refer to this page for detailed specifications of the AK7455.
