Magnet ring for engines | Hutchinson
Magnetic Encoders for Engines

Our magnet ring for engines determines very precise measurements of the position and the rotation speed of the crankshaft or the camshaft. They transmit an accurate and optimized input signal to the electronic control thanks to the sensor. Our solution pinpoints the precise position of the top dead center of the engine, helping carmakers improve their Stop & Start systems and fuel injection management.


The quality of the signal you can reach with Hutchinson magnet rings for the camshaft allows you to have a very good back up solution to replace crankshaft signal.
