The recommended products are divided into two application categories depending on how the magnetic field acts on the sensor
Open/close: These movements are detected from changes in magnetic field strength.
Rotation: Detected from changes in the direction of the magnetic field.
If an AMR sensor designed for open/close detection is used for rotation detection, it can only be switched on in a narrower range of angles compared with the right product.
If an AMR sensor designed for rotation detection is used for open/close detection, it may be prevented from being switched off when there is no magnetic field.
