Abstract
(DE) Ein Sicherheitsschalter, der insbesondere zum Überwachen einer Schutztür an einer automatisierten Anlage vorgesehen ist, be­sitzt einen Betätiger (16) und einen Sensor (18). In dem Betä­tiger (16) ist eine Betätigerantenne (56) und in dem Sensor (18) eine Sensorantenne (46) angeordnet. Betätiger (16) und Sensor (18) sind in der Schliessposition der Schutztür transfor­matorisch, insbesondere transponderartig, miteinander gekop­pelt. Gemäss einem Aspekt der Erfindung besitzt die Sensoranten­ne (46) eine magnetische Richtcharakteristik, die ausgehend von der Sensorantenne (46) in zumindest zwei zueinander senkrechten Raumrichtungen (64, 66, 68) eine transformatorische Kopplung mit dem Betätiger (16) ermöglicht.
(EN) The invention relates to a safety switch which is provided, in particular, for monitoring a protective door on an automatic system. Said safety switch comprises an actuator (16) and a sensor (18). An actuator antenna (56) is arranged in the actuator (16) and a sensor antenna (46) is arranged in the sensor (18). The actuator (16) and the sensor (18) are coupled together in the closed position of the protective door, in a transformatory, in particular, transponder-type manner. According to one aspect of the invention, the sensor antenna (46) comprises a magnetic directional characteristic, which enables the actuator to be coupled in a transformatory manner in at least two spatial directions (64, 66, 68) which are perpendicular in relation to each other based on the sensor antenna (46).
(FR) L'invention concerne un interrupteur de sécurité servant notamment à surveiller une porte de protection d'une installation automatisée. Cet interrupteur de sécurité présente un actionneur (16), dans lequel se trouve une antenne d'actionneur (56), et un détecteur (18), dans lequel se trouve une antenne de détecteur (46). L'actionneur (16) et le détecteur (18) sont couplés l'un à l'autre par un transformateur, notamment par un transpondeur, lorsque la porte de protection se trouve en position de fermeture. Selon un aspect de l'invention, l'antenne de détecteur (46) présente une caractéristique directionnelle magnétique qui permet un couplage par transformateur avec l'actionneur (16) à partir de l'antenne de détecteur (46) dans au moins deux directions spatiales (64, 66, 68) perpendiculaires.
