Magnetic Angle Position and Contactless HMI Sensors

If you are a developer of applications which requires angle detection, you might encounter several issues to improve contact volume lifetime and off-set, or encoder space limitations, or need to improve angle detection performance for low power applications.

MPS’s MagAlpha^TM Magnetic Angle Sensor product family will help you to solve those issues.

MagAlpha^TM Magnetic Angle Sensor Product Family

The MPS MagAlpha family of magnetic angle position sensors offers a revolutionary way to measure angles. The MagAlpha range offers unique performance advantages compared to rival magnetic sensing technologies.

Magnetic Angle Sensor IC & SpinAxis Angle Detection Method

Advantages of MagAlpha Angle Sensors

Instantaneous, Absolute Angle Sensing

High Resolution up to 15-bits

High Bandwidth up to 21kHz

Low Total Error (INL) <0.1°

Ideal for Battery-Powered Applications with <0.5uA Idle Current

Smallest Footprint: 2mm x 2mm x 0.6mm UTQFN

Flexible Sensor Placement: Side-Shaft or On-Axis

SpinAxis^TM Hall measurement technique

MagAlpha sensors use the patented SpinAxis^TM Hall measurement technique that provides instantaneous angle position in a digital format. SpinAxis uses a phase detection approach that eliminates any need for analog to digital conversion or complex angle calculation used by more traditional technologies.
