The S-line radio small tubular motor is a self-learning radio tubular motor with a soft stop. It has an integrated interface for quick and easy integration into the Rademacher radio system. Thanks to plug & play, it can be installed in a particularly time- and cost-saving manner, as the tubular motor does not require any end point learning or a learning run. All that is required for self-learning are rigid shaft connectors or fastening springs as well as stoppers or a stopper strip. The motor automatically detects whether rigid shaft connectors or fastening springs have been used. The motor has precise position detection and torque monitoring and protects the roller shutter with its integrated blockage detection and its particularly sensitive obstacle detection. As soon as the roller shutter is blocked or has hit an obstacle, the motor reverses.
