Electrical linear actuators of the LME... / RSD ... series are the optimal solution for the operation of final control elements with preferably linear movement. The internal rotary / linear conversion is done virtually wear-free and the actuator thrust rod transfers the force directly to the final control element. Electrical linear actuators of the RSDE… series are designed for the use in hazardous areas. They are controlled via standard electronic units, loaded with specific data for the explosion-proof actuators. These electronic units for field or rack installation are installed in the non-hazardous area.
