ABSTRACT:
A system and method for setting the activation state of electronic article surveillance markers, tags, and labels being transported on a conveyor system is provided. The system includes a pair of electromagnetic transmitting coils mountable on opposite sides of a conventional conveyor section, an electronic controller, and can include a remote external controller for manual operation. The electromagnetic transmitting coils are mounted within sensor housings that include one or more sensors to automatically sense an article traveling on the conveyor system and trigger the transmission of preselected activation or deactivation electromagnetic pulses when the article is in the proper location. The system can include an inhibiting sensor input to prevent the automatic transmission of an activation/deactivation pulse for specific preselected articles. The system includes a logic scheme to preselect and shape the activation or deactivation electromagnetic pulse.
