Linear Output Hall Effect
The Hall effect is based on the force acting on electrical charges in motion, known as the Lorentz force. When a negatively charged particle, known as an electron, moves along an axis at right angles to a magnetic field, it experiences a force at right angles to both directions.

Output Voltage
-
A linear Hall effect sensor provides an output voltage proportional to the magnetic field applied. A typical, linear architecture, Hall effect, integrated circuit consists of a source of steady current, or bias, the Hall effect sensor itself, a differential amplifier and a regulator circuit.
Linear Position
-
The linear output voltage from the Hall effect sensor can be converted into a meter reading that indicates the linear position of the assembly moving the magnet. Amplifying the output voltage increases the sensitivity of the measurement.
-
Applications
-
Linear output Hall effect sensors are employed to sense the position of pedals, suspension and valves in automotive applications. They are also used for battery management and motor control.
