Contactless position sensors are used almost everywhere- from game controllers to autonomous vehicles. And Allegro's linear position sensors are used almost everywhere, too.
Allegro's low latency, high accuracy angle sensors are ideal for high speed motor applications. With signal path latency of only 10 microseconds, our ICs can work at rotational speeds up to 30,000 RPM.
