Magnetic Encoders (GMR Sensors)
Hitachi Metals is developing and manufacturing a magnetic sensor utilizing magnetic recording head technologies. Magneto-resistive (MR) and giant magneto-resistive (GMR) sensors offer high magnetic sensitivity for a wide variety of markets, such as rotary and linear magnetic encoders.
Key Features of our Magnetic Encoders
- Demonstrates a much higher level of magnetic sensitivity than MR sensors
- Surface-mounted sensors appropriate for miniaturization
- Operates in severe environments within a wide range of temperatures
