The design of the 61 series cylinders is safe and facilitates sanitary processing and washing, which is of great importance for the food industry. The location of the piston is determined by the magnetic location sensors, which are installed directly in the cylinder body grooves. The cylinders of this series are equipped with damping devices at the end of the move with braking intensity adjustment. In addition, the piston has plastic washers to provide a silent stop in extreme positions.
