Zero Power Consumption Sensor WG631 Features - No need the power supply when it works. - Bipolar excitation working mode, thesensor outputs a pair of positive andnegative electrical pulse signal when themagnetic field polarity changes for a circle. - Only when the external magnetic fieldpolarity changes, and magnetic strengthreaches the excitation threshold, the sensorwill outputs a pulse signal, so the vibrationwon’t happen. The operation is stable andreliable. - The signal amplitude has nothing to dowith the magnetic field changing speed, andit can work at the speed near to zero. - The output signal can be remote transmittedby the signal lines, so it’s suitable for LANmanagement. - No mechanic contact, no spark, is a kind ofintrinsic safety devices. - Wide operating temperature range, strongenvironmental adaptability. Principle description Zero power consumption sensor WG631 （It also called Wiegand sensor）, it is a kind ofnew type magnetic sensor, which is produced based on Wiegand effect theory, it can active produce energy. It no needs external power supply when it works, it can send sharp voltage pulse signals, The sensor is consist of alloy wire which is special processed, induction coil which winds outside, frame and lead wire.
