Wiegand sensors – tiny devices that use variations in an external magnetic field to generate electrical signals and energy – have unique properties that make them a useful option for proximity sensing systems. Wiegand sensors are built around small sections of Wiegand wire, a specially prepared ferromagnetic alloy that has a unique physical property. When […]

Wire energy harvesting components
POSITAL’s Wiegand assemblies offer a compact and efficient way of harvesting power for electronic circuits in electromechanical devices, eliminating the need for backup batteries. The operating principle of POSITAL’s Wiegand modules is simple. A “Wiegand wire” is a short length of specially prepared Vicalloy (vanadium-iron-cobalt) wire. When exposed to a changing external magnetic field (e.g. […]
