This sensor is made from InSb magnetic resistance. That resistance value changes by the magnetic field and the permanent magnet which gives this sensor magnetic bias. When a magnetic substance approaches the detection side, an output signal can be received because the magnetic flux density which affects the magnetic resistance changes and the resistance value of this senser is changed. It is wide with the detection width 63mm in total by 7 channels, and characteristics can take in many magnetic data by the composition.

Feature

MRS-134 is the multi-channel MR sensor of the detection width 62mm.
・ Elements are arranged onto the same straight line to detect safety thread of the bill securely. It can get output steadily from the sensor by the width of 62mm.
