Abstract (en)

The safety device monitors the handrail (2) e.g. of an escalator. It has at least one sensor (13) in the region of the handrail guide (4) under the handrail. The sensor operates on the capacitive principle. It includes a long feeler, which is positioned under the handrail, but not in contact with it. A potentiometer may be used, with a maximum value setting for switching off the drive.
