Primary Applications for GMR Sensors (Magnetic Encoders)

Rotary linear encoders, motion sensors and position-detection sensors

The Low-Resistance Variation Rate of the GMR Membrane

GMR Principles

When an external magnetic field is added and the direction of the magnetism of each magnetic layer becomes unified, the elemental electrical resistance decreases.
