Zusammenfassung: | The panel (1) sliding in an opening (5) is driven by an electric motor (M) under electronic control (3) which responds to detection of an obstruction (13) by a sensor moulding (7) along the edge (6.2) of the panel. The sensor operates on the transponder principle with transmission based on an AC electromagnetic field (15) of constant frequency above 100 kHz. The signal excites a response circuit (9) varying the radiation from a base station (11) which generates a sensor signal (S) for the control. When this exceeds a preset threshold, the drive (2) is interrupted or reversed. |
