MRE-Type Non-Contact Position Sensor

We have developed a non-contact position sensor to obtain linear output using a ferro-magnetic magneto-resistance element (MRE) with good characteristics of endurance and extremely high sensitivity to low magnetic fields. This position sensor consists of a MRE and a rectangular magnet. It has an extremely stable and linear output, and good endurance to the environment, using saturated magnetic field characteristics of MRE.

This non-contact position sensor has wide industrial applications and can be used for automotive parts.
