AMR Sensors (Magnetic Sensors)

These products are magnetic sensors using AMR elements whose resistance varies according to the strength or direction of the magnetic field. Combination with a magnet permits non-contact rotation detection or position detection.

Product Lineup

These are magnetic switches that are built-in IC that output H/L digital signals based on magnetic field strength.
Magnetic switches are being widely used for cylinder-position detection applications, rotation detection applications such as in gas and water meters, and opening/closing detection applications such as in single-lens reflex cameras, video cameras, and refrigerators.

Basics

Learn about the basics of AMR (magnetic) sensors, including their general characteristics and advantages, how they differ from other types of sensors used, and more.

Application Guide-Usages and Applications-

See how opening/closing detection, position detection, and rotation detection are used and examples of how they are applied.

Simulation Tool

Download a tool that enables you to easily simulate the relationship between the positions (the ON/OFF area) of the AMR sensor and the magnet.
