3D magnetic Hall sensor
Infineon’s broad range of 3D magnetic sensors for applications requiring compact, high-accuracy solutions with low power consumption
A 3D magnetic position sensor is a valuable device that can detect the strength of a magnetic field on x-, y-, and z-axes. It can measure three-dimensional, linear, angular, and rotational movements and transmit the data via an output interface. 3D magnetic sensors can provide accurate measurements and only require a small amount of power to operate.
3D position sensors are also known as 3D Hall effect sensors, because they operate using Hall technology. The Hall effect, a longstanding method of magnetic field measurement, achieves measurable voltage by placing a magnet perpendicular to a flat conductor. Charge carriers – which carry current throughout the conductor – get disrupted by the magnet’s magnetic field, and their protons and electrons jump to opposite sides. With the positive and negative charges separated, a meter can quantifiably measure the conductor’s voltage.
A 3D Hall-effect position sensor linked with a magnet relays signals when the magnetic field’s power changes. Whether for determining proximity, angle, or rotation, changes to the magnetic field’s strength indicate position changes or abnormalities to the magnetic sensor via Hall effect, which then get sent to the operating system.
