If the magnet is mounted on a mobile element, the sensor will indicate when the desired position is reached
This is done by measuring the variance in resistance
Devices of this type, based on the physical principle of the Hall effect, are widely used as proximity, positioning, speed, and current detection sensors
They are used where very long sensing ranges are required
Part #
In combination with a magnet the sensor can be used for position sensing in a variety of applications
Sep 24, 2018 · Some magnetic field sensors can provide three-dimensional position information
magnetic sensor system relies on the alignment of these moments within the label to produce a measurable fringe field

Magnetic angle sensors from Infineon offer best performance and highest quality for automotive and industrial applications
In position sensing, two major categories of magnetic sensors are Hall effect sensors and MR sensors [153] [154] [155
This sensor uses a Hall effect transducer, and measures a vector component of the magnetic field near the sensor tip
The sensor thus recognizes the field of the magnet integrated into the piston through the actuator wall
In industrial and automotive applications in particular, the magnetic sensors ability to withstand the dust, dirt, grease, vibration and humidity that commonly disable optical encoders – the best known alternative contactless type of position sensor – is highly valued
