Abstract

MARCADOR MAGNETICO PARA UTILIZAR CON SISTEMAS ELECTRONICOS DE VIGILANCIA DE ARTICULOS (EAS) EN EL QUE SE OBTIENE UNA RESPUESTA BIDIRECCIONAL ARMONICA DE ORDEN SUPERIOR. LOS MARCADORES CONSTAN DE DOS PARES DE TIRAS ALARGADAS DE MATERIAL DE BAJA FUERZA COERCITIVA Y ALTA PERMEABILIDAD SITUADAS COMO EN EL JUEGO DE LAS TRES EN RAYA, DE FORMA QUE LAS TIRAS EN ANGULO RECTO CON UN CAMPO APLICADO DE UN SISTEMA EAS RECOGEN Y CONCENTRAN LAS LINEAS DE FLUJO ASOCIADAS CON EL CAMPO SOBRE LAS TIRAS PARALELAS A ESTE, SIENDO SUFICIENTE EL FLUJO CONCENTRADO PARA PRODUCIR UNA ALTA RESPUESTA ARMONICA.
