Wiegand Effect

POSITAL's rotary encoders are engineered to utilize the principles of Wiegand technology, a physical phenomenon first observed by John Wiegand in the 1970s. Wiegand discovered that a specifically treated piece of ferromagnetic alloy, known as Wiegand wire, responds uniquely to a reversing external magnetic field. It maintains its magnetic polarity until a specific point, after which it quickly switches to the opposite polarity within a few microseconds.

The rapid shift in magnetic polarity generates a current pulse in a nearby copper coil. Interestingly, this occurs without necessitating any external voltage or current application, thanks to the inherent properties of POSITAL's Wiegand sensors. The sensors' material attributes ensure the production of consistent pulses with each switch of the magnetic field polarity.

This characteristic positions POSITAL's Wiegand sensors as an ideal solution for magnetic sensing in low-power and energy-efficient applications, given their ability to produce consistent, reliable results without additional power inputs.

Pulse Energy Harvesting

The consistent pulse production of Wiegand sensors also has a unique utility in energy provision for ultra-low power electronics. A single pulse is capable of operating such electronic systems. Moreover, successive pulses can be stored and used later to balance the energy demand of low-power circuits.

In another practical application, these pulses can serve as triggers to activate or 'wake-up' circuits that are powered intermittently. This functionality expands the sensor's applicability beyond just magnetic sensing.

There's also the potential to leverage both the magnetic sensing and energy harnessing capabilities of these pulses simultaneously. For instance, the energy from the pulses could power ultra-low power circuits that, in turn, use the pulse timing to execute specific tasks, such as counting event data. This dual functionality enhances the overall efficiency and versatility of applications integrating POSITAL's Wiegand sensors.
