Signal-Type Wiegand Sensor WG311

Signal-Type Wiegand Sensor WG311 Wiegand Sensor Signal Type Wiegand Sensor Supplier ◆ Features 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 won’t happen.
