    Abstract: The contactless magnetic sensor consists of at least one excitation coil (10) connected to the source (20) of alternating signal. In thejcavity of the excitation coil (10) is located a magnetic field sensor (40) and its output is connected to the input of the amplifier (60). The sensor includes an excitation modulator (21), which is connected to the source (20). Output of the amplifier (60) is connected to the input of a low-pass filter (80), to the input of a band-pass filter (81), and to the input of a high-pass filter (82). The source (20) generates alternating, advantageously rectangular-shaped current, which generates an alternating current magnetic field around the excitation coil (10) that interacts with materials in the excitation coil (10) vicinity. The magnetic field sensor (40) may be an anisotropic magnetoresistor AMR or a Hall probe. In case of an AMR sensor the excitation signal of the excitation coil (10) is connected via the separating capacitor (30) directly to the flipping input of the AMR sensor coil. Since the excitation signal of the excitation coil (10), and therefore the generated magnetic field are in-phase, and the magnetic field sensor's output is modulated by the flipping circuit, the result is a controlled rectification of the sensor's output signal and self-demodulation of the output signal. The output of the sensor may therefore be used for position detection, proximity detection or discrimination of materials in the coil vicinity.
