Magnetic Fields

Magnetoresistive (MR) Sensors

Magnetoresistive sensors can determine the change in earth's magnetic field due to the presence of a ferromagnetic object or position within the earth's magnetic field. The high bandwidth allows detection of vehicles and other ferrous objects at high speeds. The sensors are contactless and the working distance is dependent on the ferromagnetic mass it is measuring. Applications include Compassing and Navigation, Vehicle Detection, Virtual Reality, Laboratory Instrumentation, Medical Instruments, Underground Boring Equipment and Flux Gate Replacement.
