The optimal magnet for TMR angle sensors
Magnetic field distributions that reduce angular errors can be made by combining it with our TMR angle sensors due to the adoption of an isotropic bonded NdFeB magnet.
Magnetization to minimize the error of angle
High robustness against the setting area between
magnet and TMR angle sensor
For EPS angle sensor
For control system of wiper motor
For other automotive angle sensor
The distance between magnets and TMR angle sensors, and the relationship between the magnetic flux density and radius that can attain an angular error of 0.1 degrees or below
Positional relationship between magnets and sensors
Disc Magnets for Tunnel Magneto-Resistance (TMR) Angle Sensors distributes a magnetic field to reduce angular errors. These magnets offer high-reliability and a magnetization to minimize the error of angle. The magnets for TMR angular sensors feature a high-robustness against the setting area between the magnet and TMR angle sensor. Typical applications include EPS angle sensors, the control system of the wiper motor, and an automotive angle sensor.
What are TMR sensors and what applications are they best suited to? This article provides a snapshot of this sensor type and what TMR-based components are available for designers.
Magnetic field sensors are popular choices for position sensors for a variety of reasons. They are non-contact sensors, which means there are no parts to wear out. The reduction in mechanisms also means there are fewer parts to assemble and fewer parts to fail in a design. Some magnetic field sensors can provide three-dimensional position information.
Magnetic field sensors use one of three physical phenomena to detect the intensity and direction of a nearby magnetic field: anisotropic magnetoresistance effect (AMR), giant magnetoresistance effect (GMR), and tunnel magnetoresistance effect (TMR). MPCO Magnets for TMR Angle Sensors
