In order to communicate an object’s position, a magnetic position sensor examines it and delivers a signal with quantifiable data. Since positional data can be utilised to start alarms, manage system operations, and automate particular actions, usage of this signal varies greatly.
When in close proximity to a magnetic field, magneto resistive materials undergo size and form changes. By observing these variations, a magneto resistive position sensor can determine the object’s location.
A position magnet must first be attached to the object to be measured in order to accomplish this. A magneto resistive wire carrying an electric current generates a second magnetic field that interacts with the magnetic field cast by this magnet.
Since magnetic position sensors are non-contact devices that don’t require physical contact with the object being measured, they endure less wear and tear. They have fewer parts than other kinds of sensors, which makes them simpler to put together and less likely to malfunction.
The measurement method will fall into one of the following categories: anisotropic magneto resistive (AMR), giant magneto resistive (GMR), tunnel magneto resistive (TMR), or Hall sensor technology, depending on the sensing capabilities of the magnetic position sensor IC.
The Global magnetic angle sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
