The SM3600AP is a magnetic sensor module that incorporates magnetic sensor elements, amplifier IC, and bias magnet in a single, compact package. Integration of the functions in a compact package decreases the susceptibility of error due to external noise.
It employs ultra-small nano-granular TMR*1 type magnetic sensor elements and an amplifier IC with an auto bias function built-in to achieve high-sensitivity magnetism detection and high-stability output characteristics. The SM3600AP can detect magnetic inks used in securities (stocks and bonds) using a non-contact method, making it ideal for a diverse range of discrimination devices.
