  • Safety switch for monitoring a closed position of two parts moveable relative to one another
    Patent number: 7746233
    Abstract: A safety switch, which is particularly intended for monitoring a guard door on an automated installation, has an actuator and a sensor. The actuator comprises an actuator antenna and the sensor comprises a sensor antenna. The actuator and the sensor are coupled to one another like a transformer, in particular like a transponder, when the guard door is in the closed position. According to one aspect of the invention, the sensor antenna has a magnetic directional characteristic which allows transformer coupling with the actuator in at least two mutually perpendicular spatial directions as seen from the sensor antenna.
