AMR Sensors (Magnetic Switches)

Murata offers a broad product portfolio of AMR sensors for wide range of

consumer and industrial applications including open-close detection for consumer

electronics and white goods, flow rate detection for smart gas and water meters,

and position sensing for cylinder switches. More than 30 part numbers support

diverse design and performance needs.

Murata AMR sensor is a sensing device utilizing the Magneto Resistance

effect. It is comprised of four AMR elements and a IC circuit. Features include

high sensitivity, narrow sensitivity spec range, design flexibility, and reliable

performance in different operating conditions.
