Working Principle

The HAL1823SF-A is equipped with a 3D sensing structure that enables it to accurately detect the magnetic field vector in real-time regardless of the angle and orientation of the sensor. It consists of three linear magnetic field sensors located in the X, Y, and Z axes. The sensors utilizes high precision Hall effect technology based on processable ferromagnetic material, which increases sensor linearity and provides a strong signal-to-noise ratio. The directional sensitivity of the sensors enables the efficient detection of the magnetic flux density vector within an area of ±2°. When the sensor is subject to a measureable magnetic field, each of the three integrated Hall elements will output a voltage signal based on the intensity of the field applied. The sensor then utilizes the three signals from the respective Hall elements and synthesizes the geometrical vector positioning of the applied magnetic field. The output from the sensor can be read easily with an analog-to-digital converter (ADC) which calculates the position data from the sensors in an x, y, and z axis format.
