No need the power supply when it works.
Only when the external magnetic field polarity changes, magnetic strength reaches the excitation threshold, the sensor will outputs a pulse signal, so the vibration won't 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 signal processing is simple, and it can be directly connected with transistors, comparators, A/D converter, etc.
The output signal can be remote transmitted by the signal lines, it's suitable for LAN management.
No mechanic contact, no spark, is a kind of intrinsic safety devices.
Wide operating temperature range, strong environmental adaptability.

Instruction
Note: The sensor has certain requirements to the magnetic strength, too strong or too weak magnetic field may affect its operation.(See the excitation strength on "Performance index" )
The working mode is shown as the following right figure.(if using other shape magnet, the installation distance should be adjusted.)
