Magnetoresistive Current Sensor The NT Series is a current sensor that accurately measures dc and ac currents and provides electrical isolation between the circuit being measured and the output of the sensor. The unique magnetoresistive effect technology allows for the compact design that can be mounted directly to the PC board.
