Abstract
A pulse generating unit in which a Wiegand wire module is contained within two soft iron ferromagnetic members which act as shunts in that they collect, conduct and guide flux incident on the pulse generating unit toward an air gap between the two shunt elements. the air gap is approximately at the center of the Wiegand wire module. Cylindrical cavities in these two shunt elements shield the ends of the Wiegand wire thereby minimizing the incidence of external flux on the Wiegand wire. Saturation of the flux at the air gap between the two shunts causes leakage of flux to be available to switch the state of the Wiegand wire.
