Magnetic ring for industrial applications

Thanks to the expert technical know-how of magnetic systems, we offer different types of encoders perfectly adapted to match various families of sensors. Typically: Hall Effect, AMR or GMR sensors.=

Hutchinson develops magnetic rings, made of a metal insert bonded together with a rubber matrix filled with magnetic particles. The rubber compounds that we design, respond reliably to heavy duty applications, combining elastic properties and strong rubber/insert adhesion under extreme conditions of usage (mud, sand, salt, oils & greases). Ideal solution for high speed up to 25000 RPM.

Our solutions enable to reach high measurement accuracy. They are applied in position and speed controls for safety and maintenance purposes. They are key components in the age of digital.
