How big is the magnetic sensing market?

June 29, 2018 By Randy Frank

Angle, position and current sensing, as well as compasses and even some switches, rely on magnetic sensors. While Hall-effect technology has been a dominant enabler of these sensors, so-called xMR or magnetoresistive/magnetoresistance technologies are playing an increasing role. The x can stand for anisotropic (AMR), giant (GMR) or tunnel (TMR). With these new technologies playing a key role, market researchers at Yole Développement (Yole) project that the magnetic sensor market will experience a 7% compounded annual growth rate (CAGR) between 2016 and 2022. The company’s  Magnetic Sensor Market & Technologies report discusses the applications, the sensor functions, and key requirements. In addition to key market metrics and dynamics, the report provides key technical insight into future technology trends and challenges. Automotive and internet of things (IoT) are especially popular targets for motion sensors to convert motion into an electrical signal, to provide information and intelligence from unanimated objects. The report includes information about the magnetic sensor players and their market share and technological position.

One of the newest magnetic sensing products that demonstrate continued innovation in Hall sensors comes from ams. The AS5200L is a dual-die magnetic rotary position sensor with an I2C interface that targets space-saving designs in safety-critical automotive applications.

Ideal applications include contactless motion control knobs and joysticks in electrified powertrain drive-by-wire control functions, such as shift-by-wire for both traditional stick and rotary shifters as well as pedal applications.

In its MLF-16 package, with a footprint of just 5 mm x 5 mm, the AEC-Q100 grade 1 qualified AS5200L’s angle measurements are supplied in 12-bit resolution with a maximum error attributable to inherent non-linearity of ±1°.
