OMNIDITIONAL MANAGEMENT ACTIVATOR FOR MAGNETICAL LABELS OF WATER CONTROL SYSTEMS

摘要

An EAS tag or label deactivator having a central area and an edge area bordering the central area. The central area is formed from magnetic regions having alternating magnetic polarities arranged in a checkerboard pattern. The edge area is formed from a linear multipole magnet having magnetic regions of alternating polarity. The sides of the magnetic regions of the linear multipole magnetic are sized to be of lesser extent than the sides of the adjacent magnetic regions of the central area.
