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 changes, and 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, so 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.
