Hall-effect vane sensors are widely used in automotive systems, industrial automation, consumer appliances, and compact robotics because they provide accurate position and speed information with simple mechanics and high robustness. In these sensors, a thin soft-magnetic vane modulates the magnetic flux between a fixed magnet and a Hall element. This approach ensures clean digital transitions or stable analog output even under harsh conditions such as dust, oil, vibration, or temperature fluctuations, while maintaining reliable switching behavior during startup without requiring…
