General Description
OHWG series wiegand sensor is new-type magnetic sensor based on wiegand effect. It can convert the magnetic signal into voltage output without additional power supply, so it is also called zero power magnetic sensor. Wiegand sensor is composed of magnetic bistable function alloy wire made by special processing and induction coil winded outside.

FEATUREs
• No additional power supply during operating time
• When trigger magnetic induction intensity is 2mT, the output voltage amplitude could reach 1V. When 8mT, the output voltage amplitude could be higher than 4V
• Amplitude of output signal has nothing to do with the change rate of magnetic field, achieving “zero speed” sensing
• No touching point, enduring erode, water-proof, explosion-proof and having a lifespan of 2 billion times
• Achieving electrical signal long-distance transfer by using telephone line and coaxial line,etc.

APPLICATIONs
   Wiegand sensors are used in water, gas, and electric meters for electronic indexing. They also havemany automotive applications such as antilock braking, speed sensing, and position indicators. They have been used in anemometers and other wind speed applications, machine controls, shaft speed sensing, and numerous rotational counting applications.
