The sensors using magneto-resistive elements (MR elements) can detect a change in magnetic field as a change in voltage. They are mainly utilized in distinguishing paper currencies.

MR Sensor Single Type

This is a single channel type MR sensor, which can detect not only a specified area but also a wide area if multiple MR sensors are combined.

MR Sensor Multi Type

This is a multiple channel type MR sensor, which detects a wide range with only a single sensor.
