GMI® Rotary Encoder


Precision and Versatility

An all-inclusive solution to stand out in any situation, the GMI® Rotary Encoder offers high accuracy, repeatability, and resolution.

Make your application stand out with a precise, versatile, all-in-one solution.

The Giant Magneto Impedance (GMI®) technology, developed and patented by FLUX for position measurement, capitalizes in an exceptional way the interaction between magnetic field and electromagnetic induction.

Hysteresis-free, absolute performance combined with robustness and large mounting tolerances guarantee flexibility in any situation and provide highest accuracy, repeatability, and resolution without compromises. IP67 Aluminium or steel housing for use in harsh environments as well as plug-and play options make the GMI® Rotary Encoder a reliable all-rounder for a limitless area of operations.
