KMC05, Magnetic Field Sensors Current Sensor

Magnetic Field Sensors Current Sensor KMC 05 Function principle Magnetoresistive materials can change their resistivity in an external magnetic field.

The variation of the resistivity is determined by the rotation of magnetisation with respect to the direction of the current flow.

Permalloy (Ni81Fe19) is commercially used as magnetoresistive material.

The relative change of resistivity is 2-3 % for this material.

The high sensitive and small size sensor consists of a silicon chip coated with thi
