Stroke control The stroke control system consists of two built in magnets and two external sensors (Id.-Nr. 71834910) reading the axial position of the cylinder piston and consequently of chuck jaws mounted on it. The stroke control gives the following signals: „chuck fully open“, „chuck fully closed“ or „part clamped“ positions.
