Abstract

Die Erfindung betrifft ein Element (1) für die elektronische Artikelsicherung oder für die Sensortechnik, bestehend aus einem streifenförmigen oder drahtförmigen Barkhausenmaterial (2) einer vorgegebenen Länge (L), das in einem externen magnetischen Wechselfeld zur Aussendung eines charakteristischen Signals angeregt wird, und einem weichmagnetischen Material, das dem Barkhausenmaterial (2) zugeordnet ist.
Der Erfindung liegt die Aufgabe zugrunde, ein kostengünstiges Element für die elektronische Artikelsicherung oder für die Sensortechnik vorzuschlagen.
Die Aufgabe wird dadurch gelöst, daß das weichmagnetische Material aus einzelnen Abschnitten (3) einer vorgegebenen Länge (a) besteht, die in einem vorgegebenen Abstand (b) voneinander angeordnet sind, und daß die Abschnitte (3) des weichmagnetischen Materials bezüglich des Barkhausenmaterials (2) derart positioniert sind, daß die von ihnen erzeugten magnetischen Streufelder mit der Magnetisierung (M) des Barkhausenmaterials (2) koppeln.
