Magnetic Speed Sensors

We offer the most comprehensive portfolio of magnetic speed sensors ICs, covering the full range of speed and speed with direction, two- and three-wire interface, magnetic encoder (ring magnet) and gear tooth sensing, Hall and GMR technology, and ASIL-compliant options for transmission, wheel speed, engine, e-motors, and many more encoder and gear tooth sensing applications. 

Our innovative Hall-effect and GMR technologies provide the most robust and reliable gear tooth and ring magnet speed sensing in the world.

Thanks to decades of application and algorithm experience and close collaboration with OEMs, we develop application-specific speed sensor ICs that are optimized for your target applications—improving safety, reliability, and performance.

Our magnetic speed sensors offer:
  • Dynamic compensation for system-level variation (i.e., target runout, vibration, thermal gradients) reducing design-in complexity and costs and increasing reliability.
  • Integrated packaging for EMC protection, as well as optional magnetic biasing that simplifies design and assembly while improving performance.
  • Integration of discrete components to eliminate the need for external PCB and components, significantly reducing total system cost (third generation GTS packages).
