At a glance

1 Trend No. 1: The electrification of systems
Position sensors measure complex angles with high accuracy throughout evolving automotive systems, including electric motors and electric power steering (EPS) systems.
2 Trend No. 2: The need for increased reliability and safety
Shifting from mechanical systems to magnetic sensors reduces wear and tear while increasing the need for functional safety.
3 Trend No. 3: The miniaturization of overall end-product form factors
High-sensitivity magnets and greater integration address trade-offs of miniaturization, including lower accuracy and resolution.
4 Trend No. 4: The transition from rare earth materials to ferrites
Ferrite is an abundant and cost-efficient alternative to rare earth materials in magnetic sensors but requires features to compensate for its reduced magnetic field and temperature drift.
