Abstract

Um ein Warensicherungselement (1) bereitzustellen, welches bei geringem wirtschaftlichen Fertigungsaufwand miniaturisierbar ist und darüber hinaus in kleinste und vor allen Dingen variierbare Gehäuseformen integrierbar ist. Die Störbarkeit soll reduziert werden und eine mutwillige Deaktivierung ausgeschlossen werden. Darüber hinaus soll die Detektionsgröße erweitert werden, so daß die Antennen der Sende-/Empfangs-Anlagen verkleinert und/oder die Abstände vergrößert werden können, wird mit der Erfindung vorgeschlagen ein Warensicherungselement zur Verwendung in Verbindung mit akustomagnetischen Sende-/Empfangs-Systemen, bestehend aus einem stabförmigen Ferritelement, wenigstens einer Spule (10) in Form einer auf das Ferritelement aufgebrachten Kupferdraht-Wicklung und einem zur Spule (10) parallel geschalteten Kondensator (11).

Figure 00000001
In order to provide a goods security element (1) which can be miniaturized with little economic production effort and, moreover, can be integrated into the smallest and, above all, variable housing shapes. Interference is to be reduced and deliberate deactivation is to be excluded. In addition, the detection size is to be expanded so that the antennas of the transmitting / receiving systems can be reduced and / or the distances can be increased. The invention proposes an article security element for use in connection with acustomagnetic transmitting / receiving systems consisting of a rod-shaped ferrite element, at least one coil (10) in the form of a copper wire winding applied to the ferrite element and a capacitor (11) connected in parallel with the coil (10).
