Magnetic pattern recognition sensors combine InSb (indium antimonide) magnetoresistive elements with a permanent magnet, enabling feeble magnetic information to be easily detected. The features of these sensors are wide dynamic range, wide gap characteristic, and high output, enabling detection of either ferromagnetic or magnetic patterns.

Murata's rotary sensors employ magnetoresistors incorporating InSb (intermetallic compound semiconductor) combined with permanent magnets. These are high-output sensors used for detection of rotation, linear motion, and proximity. The magnetoresistors and permanent magnet comprise an optimal magnetic circuit, which is protected with an oil-proof and dust-proof enclosure that is resistant to harsh environments. The output is close to an optimal sine wave, ensuring easy sampling processing.
