ELECTROMAGNETIC COMPATIBILITY CIRCUIT, SENSOR CIRCUIT AND SENSOR

The present disclosure provides an electromagnetic compatibility circuit, a sensor circuit and a sensor. The electromagnetic compatibility circuit comprises a first input inductance element, a first input capacitor, a second input inductance element, a second input capacitor and a third input capacitor. According to the electromagnetic compatibility circuit, the sensor circuit and the sensor provided by the present disclosure, the first input inductance element and the first input capacitor form a first input LC filter circuit at the input terminal; then the second input inductance element and the second input capacitor form a second input LC filter circuit at the input terminal, and the first input capacitor and the second input capacitor are connected to the case ground terminal, so that harmonics at the input terminal are derived through the case ground terminal; meanwhile, filtering is performed by the third input capacitor provided between the input terminal and the circuit ground terminal.
