The NEx-K linear drive for Ex zone applications is a further development of the flameproof housing of the NEx rotary and part-turn actuator with Ex zone 1 marking CE2004 EX II 2G Ex d IIC T6 Gb, based on IECEx certification IECEx EPS 15.0061X and ATEX certification EPS 15 ATEX 1 044 X.
NEx-K series linear actuators are utilized to precisely adjust dampers installed in all systems 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 NEx series actuators. Switch-off at limit is path dependent.
