Magnetic pattern recognition sensors are extensively used for recognition of bank note types, patterns printed with magnetic ink, and magnetic cards.
Murata’s magnetic pattern recognition sensors combine InSb (indium/antimonide intermetallic compound semiconductor) magnetoresistive elements with a permanent magnet, enabling feeble magnetic information to be easily detected. The features of these sensors include wide dynamic range, wide gap characteristics, and high output, ensuring the reliable detection of either ferromagnetic or magnetic patterns.
