Signal-type wiegand sensor wg214
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 changes, and 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 output signal can be remote transmitted by the signal lines, so it, s suitable for lan management.
No mechanic contact, no spark, is a kind of intrinsic safety devices.
Wide operating temperature ran
ge, strong environmental adaptability.
Principle outline
Zero power consumption sensor wg112 ( it also be called wiegand sensor) is a kind of new type magnetic component that is made based on wiegand effect. It can initiative generate energy, no need external power when it works. It can give a sharp voltage pulse signal. The sensor consists of a special processed alloy wire and induction coil which winds on the outside of wire , framework and pins etc.
The alloy wire owns double magnetic structure, its core is soft magnet, and the shell is hard magnet. To utilize the magnetic difference between the alloy wire, s inside and outside, under excitation by suitable strength of alternating magnetic field, the core magnetization direction everted in a moment, the direction became same or opposite with that of shell, and make the magnetic field around alloy wire changed suddenly, then a group of positive and negative pulse generated in the induction coil. The pulse amplitude is only regard with strength of the excitation field, and it has nothing to do with the field changing speed. It realized , zero speed counting detection.

Power-type wiegand sensor wg612 Wiegand sensor Power type wiegand sensor supplier L it needn't power supply when it works. L high output amplitude, and it can reach 30v when it is no-load, its high value can reach more than 40v. L bipolar motivation operating mode. When the polarity changes for 1 circle, the sensor will output a pair of plus-minus pulses. L only when the polarity of the applied magnetic field changes, and the magnetic strength reaches motivation threshold, the sensor will output a pulse signal, so no trembling occurs, and the operation is stable and reliable. L the signal amplitude is independent with the changing speed of magnetic field, and it can work under the speed close to zero. L the signal processing is simple, and it can be directly connected to triode, comparer and adc etc. L output signal can utilize signal wire to realize remote transmission, and it's suitable for lan management. L no mechanical contacts, no electric spark, it's a kind of intrinsically safe component. L wide operating temperature range, strong environmental suitability. Application L rotation counting: heavy caliber intelligent water meter, heat meter, gas meter, oil meter, flow meter, odometer, etc. L position detection: oil depot level detection, tipping bucket udometer, unattended hydro-meteorological monitor etc. L electronic switch: flame-proof switch, ignition switch etc. L impulsing power source: encoder, uwb power etc. Performance parameter.
Supplier: Wireless charger, batteries power bank, dust sensor, optical disc drive, tof, lidar, ar glass
We Can Supply Freestyle Libre 2 Flash Glucose Monitoring System Sensor Please Dont Hesitate to Contact Us in Case of Any Interested
Floating cable which can be applied to underwater robot equipment, either in fresh water environment or in seawater environment. It is widely used in marine exploration robot, underwater ROV UAV remote control submersible, underwater camera, underwater construction, underwater search and rescue robot, pipeline detection robot, submersible pump and the link between various underwater electrical equipment and shore based equipment; Link of signal transmission, power supply and equipment control system from underwater to water.
Flat Cable M&P is able to support a full line of flat cable and flat ribbon cable for electronic applications. Providing both power and data transmissions, flat cables are mainly used for internal connections within the equipment. They are available in a wide range of configurations to accommodate different connection and data transmission requirements and the range of sizes of the equipment using the cables. Flat cables provide consistent performance due to their layout and the spacing between the cables and are lighter, thinner and more flexible than other cables. Features of Our Flat Cables & Wire * Flat, ribbon and twisted configurations, with different levels of flexibility. * Shielded or jacketed cable to reduce signal interference. * Range of pitches and pin configurations to accommodate the application requirements. * Easy to fasten with clamps, adhesive, and tape. We provide custom services, including marking, kitting and custom cable design to provide you with a custom solution for your cabling application.
