Current Sensors

Leveraging our automotive qualified magnetic field sensing technology, Methode has identified an innovative approach to measuring a current’s magnetic field. By placing our highly accurate sensor coils close to the surface of a busbar, we are able to measure the magnetic field changes that are directly proportional to the applied current. The dual-channel sensor outputs respond in a differential manner, while a built in dual-stage common mode rejection enables the sensor to measure and compensate for external magnetic fields. The end-result is a highly compact, robust sensor, which offers enhanced diagnostic capabilities, making the sensor ideal for safety critical applications.
