Abstract
La présente invention concerne un commutateur électronique de sécurité fonctionnant sans contact. Ce commutateur de sécurité se caractérise en ce que la bobine L de son oscillateur C1, T1, T2, R1, R2 présente une moitié de noyau en pot en ferrite avec un champ de haute fréquence orienté vers l'extérieur. La contre-pièce de ladite moitié est formée en ferrite frittée. On a prévu un système de contrôle de courant 10 de l'amplificateur commandant les relais Re1 et Re2, à l'aide de transistors T12, T13. L'invention est utilisée pour assurer une sécurité sur les machines-outils.
