タイトルまたは説明

No need the power supply when it works.

Bipolar excitation working mode, the sensor outputs a pair of positive and negative electrical pulse signal when the magnetic field polarity changes for a circle.

Only when the external magnetic field polarity changed, and magnetic strength reaches the excitation threshold, the sensor will outputs a pulse signal, so the vibration wont happen. The operation is stable and reliable.

The signal amplitude has nothing to do with the magnetic field changing speed, and it can work at the speed near to zero.

The output signal can be remote transmitted by the signal lines, so its suitable for LAN management.
