Discover the Benefits of Smart Actuators

Smart linear actuators combine intelligent solutions with robust machinery to enable easy installation, configuration, and operation so systems can get up and running quickly and perform reliably. By incorporating these intelligent capabilities, such as those available from a variable frequency drive (VFD) or electronic programmable limit switches (EPLS), smart actuators become easier to set up, operate, adjust, troubleshoot, and monitor.
