The motion sensor BFD/A registers movements over a scope 360° with a coverage of approx. 10 m using infrared sensors and, in the event of a movement, switches a changeover contact. The retention time can be freely set between 5 seconds and 15 minutes using a 270° potentiometer. The unobtrusive housing with a clip fastening and reverse polarity protected socket is suitable for the quick assembly in intermediate ceilings. The motion sensor is used for motion dependent control processes, such as e.g. temperature or light control in offices.
