K series linear actuators are utilized to precisely adjust dampers in air-conditioning, ventilation and heating systems as well as in furnace installations, process plant engineering and other fields of industry.
They are available with the following actuating forces: 600 N, 1200 N, 1800 N, 2500 N, 3000 N, 3500 N and 5000 N. The stroke units are designed for stroke lengths of 150-750 mm. The technical construction mirrors that of series N actuators. End position limit stop is path dependent.
The standard scope of supply includes a limit switch for each end position. These are designed as changeover switches and can also perform supplementary functions such as end position indication or sequential control tasks.
