Abstract

A method for detecting the type of an exchangeable piston-cylinder unit for a dispenser, to a piston-cylinder unit having at least one radially oriented information carrier section, and at least one axially oriented information carrier section, both of which at least partially specifies the type of piston-cylinder unit, and to a dispenser having an acquisition device for automatically identifying the type of piston-cylinder unit arranged on the dispenser. The method has at least the following steps: a) detachably mounting the piston-cylinder unit on the dispenser by at least an axial movement; b) detecting completion of a successful mounting of the piston-cylinder unit on the dispenser with a sensor device; c) detecting an information of the axially oriented information carrier section; d) detecting an information of the radially oriented information carrier section; and e) determining the type of the piston-cylinder unit mounted on the dispenser from the detected information.
