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.The invention relates to an element (1) for electronic article surveillance or for sensor technology, consisting of a strip or wire-shaped Barkhausen material (2) of a predetermined length (L), which in an external alternating magnetic field to emit a characteristic signal is excited, and a soft magnetic Material that is assigned to the Barkhausen material (2).
Der Erfindung liegt die Aufgabe zugrunde, ein kostengünstiges Element für die elektronische Artikelsicherung oder für die Sensortechnik vorzuschlagen.The invention has for its object a cost-effective element for to propose electronic article surveillance or for sensor technology.
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. The object is achieved in that the soft magnetic material consists of individual sections (3) of a predetermined length (a) which are arranged at a predetermined distance (b) from one another, and that the sections (3) of the soft magnetic material with respect to the Barkhausen material ( 2) are positioned such that the magnetic stray fields generated by them couple with the magnetization (M) of the Barkhausen material (2).
