 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, 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.
