Position sensors are made up of four primary types: angle encoders, linear position sensors, absolute position sensors, and analog position sensors. Designed to measure the movement of a target object in terms of either a rotation, linear movement, or an absolute position, the AMS22U5A1BHARL326 is a comprehensive digital angle encoder system that is capable of measuring rotation, linearity, and absolute position to very high accuracy levels. This article focuses on the application fields and working principles of the AMS22U5A1BHARL326, an angle sensor.

Application Field

The primary uses of the AMS22U5A1BHARL326 includes, but is not limited to, angles of rotation in servo motors, measuring variations in crankshaft rotation in automotive machines, and finding the exact distance of travel in arduous automation applications. This advanced encoder model is also employed in stepper motors, articupators, and linear actuators. In addition, the AMS22U5A1BHARL326 enables accurate angular information acquisition regarding robots, automatic manipulators, and other automated industrial applications.

Working Principle

The hall effect is the phenomenon responsible for the working principle of the AMS22U5A1BHARL326. Basically, when a magnetic field is applied to a current-carrying conductor, a voltage is induced in the conductor. This phenomenon is known as hall effect. After the application of the magnetic field, the sensor takes a measure of the voltage and runs it through two logic circuits to derive the exact angular reading. This type of sensor takes the basic principle of hall effect and applies it to measure precise angular readings.

The AMS22U5A1BHARL326 is equipped with two major components, the the ferromagnetic core and the Hall effect magnetic field sensor chip. The ferromagnetic core is composed of an electromagnet, a cylindrical-shaped core, and an outer core made of a magnetic material. As the core is rotated inside the electromagnet, Hall effect transducers measure the variation in the magnetic field. The transducers interpret this information as an angle and relay the data to the system’s processor.

The outer core also serves as a mounting frame which can be used to fix the sensor to the object which is undergoing rotation. The ferromagnetic core has an integrated end-stop detection system which detects the presence or absence of the rotor end-stop. This is used to regulate the torque to match the application’s requirements.

Conclusion

The AMS22U5A1BHARL326 is an advanced digital angle encoder system that serves applications with large variation in rotational speed, such as the continuously variable speed transmissions found in industrial automation equipment and automotive motor control systems. It is employed in a wide range of applications, such as measuring angle of rotation for servo motors, finding the exact distance of travel in arduous automation applications, as well as providing precise angular readings in robots and automatic manipulators. The hall effect is the phenomenon at the core of the sensor’s working principle, which involves induction of voltage in a current-carrying conductor in the presence of a magnetic field.
