Working Principle of Hall Effect Angle Sensors
The Hall effect is a physical phenomenon in which a transverse potential difference (Hall voltage) is generated in a current-carrying conductor placed within a magnetic field.
Hall effect angle sensors utilize this principle: a magnet, rigidly connected to a rotating shaft, creates a magnetic field. A Hall chip, fixed within the sensor housing, precisely measures changes in the magnetic field as the shaft rotates. These changes are converted into a precise electrical signal (analog or digital) proportional to the rotation angle.
Key advantages of this technology:
Non-contact measurement (high reliability)
High accuracy and repeatability
Long service life
Resistance to vibrations and contaminants
