Abstract
Appareil photo-électrique de commutation du type à réflexion fournissant un signal de commutation significatif de la présence d'un objet. Il comporte un dispositif de projection d'un faisceau lumineux vers l'objet, un dispositif de réception de la lumière réfléchie par l'objet placé à proximité du dispositif de projection, des moyens de réglage d'axe optique commandés de l'extérieur de l'enveloppe de l'appareil 47 pour régler les axes optiques des dispositifs précités, et des éléments optiques permettant de faire passer, sur un trajet lumineux prédéterminé comportant une zone prédéterminée de travail, tant le faisceau lumineux projeté que le faisceau lumineux réfléchi, de sorte que les faisceaux 26, 36 se croisent au niveau du champ de détection souhaité, les moyens de réglage permettant de régler en permanence la distance entre l'appareil et le champ de détection. Application à la détection d'objets sur une chaîne de convoyage.
