Allegro offers 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 compliance options for transmission, wheel speed, engine, e-motors, and many more encoder and gear tooth sensing applications.
The innovative Allegro Hall-effect and GMR technology provides 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, Allegro develops application-specific speed sensor ICs that are optimized for your target applications—improving safety, reliability and performance.
Allegro magnetic speed sensors offer:
We provide fully integrated IC solutions for EMC protection and true power-on state (TPOS). Optional back-biased magnets simplify your design while improving performance.
With high performance and excellent edge accuracy, our fully integrated ICs are also highly flexible. We offer optimized solutions for engines in 2-wheelers and advanced solutions that are essential for start-stop engines.
Working on something other than a vehicle? Our portfolio provides optimized speed sensor IC solutions for many non-automotive applications.
Allegro's ICs are ready for any challenge presented by fuel-efficient 6 to 10-speed transmissions, providing you with industry-leading vibration immunity and dynamic air gap capability.
Our patented, best-in-class GMR technology provides low jitter and high air gap over the widest installation tolerance.
