Abstract: The current sensor arrangement has a sensor (3) for detecting the magnetic field induced by the current, evaluation electronics (4) for the sensor signal and a current converter coil (2) enclosing the conductor section (1a) with an annular, high permeability core (5) for supplying power to the evaluation electronics. The core contains the sensor so as to act as a screen for the sensor against external magnetic fields.

Abstract: Electronic circuit for a proximity sensor, which is target independent and uses a phase projection transformation. Circuit comprises a signal generator (1), a phase delay device (2), an oscillation circuit (3), a multiplier and a low pass filter (6). The circuit is designed so that the oscillation circuit can be driven using a square wave voltage (U1). A synchronous demodulator (5) is used for phase projection transformation. The multiplier is formed by the synchronous demodulator and an inverter (4) is placed between the oscillation circuit and the synchronous demodulator. The invention also relates to a corresponding method for operating an inventive approach sensor.
