Product Description
The Choosing Guide for Zero Power Consumption Magnetic Sensor
When the zero power consumption magnetic sensor works, it needn't power supply, it can directly transform the magnetic signal into electrical signal. The working mode is bipolar triggering, it triggers the magnetic field to change for one circle, the zero power consumption magnetic sensor will sync-output a pair of positive and negative electrical pulse.
