Sensors Overview

By utilizing leading-edge technologies such as magnetic, piezoelectric, and micro-electrical mechanical systems (MEMS), Hitachi offers a comprehensive line of sensor devices (digital compass and magnetic encoders).  Our impressive line of sensors includes giant magneto-resistive (GMR) sensors .

Magnetic Encoders

Hitachi Metals developed and is manufacturing a series of magnetic encoders based on magneto-resistive (MR) and giant magneto-resistive (GMR) materials. These encoders offer precise position indication under harsh and dirty environment and are suitable for a variety of rotary and linear applications, such as camera, industrial automation and control. The GMR encoders are available in both 20um and 40um pitches.
