Hall sensor

Hall sensors are magnetic sensing devices based on the Hall effect, which rely on non-contact magnetic field induction to complete signal acquisition. They are widely used in new energy vehicles, electromechanical control, industrial equipment, and smart home fields, where they can perform functions such as speed detection, position sensing, current detection, and limit triggering. Various types have been developed, including unipolar, bipolar, linear, Omnipolar and other Hall types.

Wiegand sensor

Zero power consumption sensor (also known as the Wiegand sensor) is a novel magnetic sensing device fabricated based on the Wiegand effect. It can generate energy autonomously, thereby eliminating the necessity for an external power source during operation, and can emit sharp voltage pulse signals. The sensor comprises a specially processed alloy wire, an induction coil wound around it, a skeleton lead and other components. The alloy wire features a dual magnetic structure, consisting of a soft magnetic core and a hard magnetic shell. Leveraging the disparity in magnetic properties between the core and the shell, when subjected to an alternating magnetic field excitation of appropriate intensity, the magnetization direction of the core instantaneously reverses, aligning with or being opposite to the magnetization direction of the shell. This induces a sudden change in the spatial magnetic field surrounding the alloy wire, thereby generating a set of positive and negative electrical pulses in the induction coil. The pulse amplitude is solely dependent on the strength of the excitation magnetic field and is independent of the rate of magnetic field change, enabling zero-speed counting detection.
