They have special qualities that make Wiegand sensors an advantageous choice for proximity sensing systems. A Wiegand sensor is a tiny device that produces electrical signals and energy by varying an external magnetic field.
Small pieces of Wiegand wire, a specially made ferromagnetic alloy with a peculiar physical characteristic, form the foundation of Wiegand sensors. A Wiegand wire will initially maintain its magnetic polarity when subjected to an alternating external magnetic field. The polarity of the wire segment will suddenly reverse, though, when the external field crosses a specific threshold. This quick polarity change can produce a distinct current pulse in a tiny copper coil that is wrapped around the ferromagnetic core. This pulse can be used to energize low-power electronic chips and is powerful enough to activate logic circuits.
The Global Wiegand sensors market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The Wiegand sensors from POSITAL provide bipolar magnetic sensing without requiring the use of any external voltage or current. Due to the sensor’s material characteristics, reliable pulses are generated each time the magnetic field’s polarity changes. The ideal magnetic sensor for low-power and energy-saving applications as a result.
The Wiegand sensors from UBITO provide self-powered, bipolar magnetic detection and deliver reliable pulses each time the polarity of an external field changes.
POSITAL, the primary supplier of Wiegand technology, has invested much in R&D with the goal of enhancing product quality and power output. In recent times, they have devised new magnet configurations for specialised uses, like ring-shaped encoders, and miniature versions of the SMD package.
