Abstract
Détecteur d'approche électronique pour constater la présence de personnes ou d'objets devant le bord de surfaces à déplacement rectiligne. Le détecteur est caractérisé en ce qu'au moins deux électrodes sont montées de façon isolée à l'intérieur du bord du panneau, que ces électrodes influencent chacune un circuit oscillant identique et que les deux circuits oscillants ainsi qu'un amplificateur et une bobine à réaction particulière sont reliés à l'inductance de base du circuit oscillant par l'intermédiaire d'une résistance à réaction réglable. Portes coulissantes notamment portes d'ascenseur.
