Abstract

A multi-directionally responsive, dual-status marker for use in electronic article surveillance systems having an alternating magnetic field within an interrogation zone. The marker comprises a piece of a high permeability, low coercive force magnetic material substantially coextensive with a piece of remanently magnetizable material, in which the first piece is configured to exhibit at least two elongated responsive areas adjacent to edges of the piece perpendicular to each other, each area having a narrow width region forming a switching section and adjacent extensive regions forming flux collectors. In a preferred embodiment, the inner edges of all of the regions are defined by a narrow band of removed material, the remaining material in the center thereby being magnetically isolated from the responsive areas. The marker is desensitized by uniformly magnetizing the pace of unmagnetizable material.
