【Sensors Converge】 Exhibition of a newly developed "Wide Range MI sensor" that is expected to be applied in the security and medical fields

Aichi Steel exhibited at Sensors Converge held in San Jose, U.S.A. from June 27 to 29, 2022. This exhibition is the nation's largest specialized exhibition of sensors and their applied technologies, systems and networks, and we continued to exhibit last year.

This event attracted many participants from all over the U.S., Canada, and Europe, and many sensor participants visited our booth more than last year.

At our booth, in addition to a demonstration of measurement of minute magnetic fields using high-sensitivity magnetic sensors, we exhibited a newly developed MI Sensor with a wider measurement range in the high-sensitivity region, which was announced in June.

Aichi Steel has successfully developed a wide-range MI sensor with an extended measurement range by feeding back a part of the MI sensor output as magnetism to the amorphous wire. In general, two coils, one for taking care of the MI sensor output and the other for magnetic feedback, are required to implement this technology. However, we have achieved both high sensitivity and wide measurement range with a single coil through the new magnetic feedback technology developed by us this time.

Magnetic Feedback Technology that Extends Measurement Range

This development is expected to lead to the detection of metals in the vicinity of MRI laboratories, which generate strong Magnetics, as well as the detection of foreign contaminants in manufacturing lines and applications in magnetic security gates.
