sensor information technology

MR Sensor is changed according to the temperature of resistance price and the ratio of change is about -2%/C, because MR Sensor use InSb of a compound semiconductor.

MR Sensor different from magnetic head can be received 50% of the sign, though there is a distance, 0.3mm away from the object examination.
It is able to examine concurrently the both sides of front and behind side, although the object of examination is thin like paper money.
