This is an LMD series Nema 8 stepper motor linear actuator with a lead of 10.16mm(0.4"). This type of actuator is composed of a highly integrated linear stepper motor and a guide rail slide. It has the advantages of simple structure and small installation space. Since there is no coupling, its accuracy is higher than that of linear actuators with conventional coupling structures. In addition, the actuator is equipped with a photoelectric sensor for detecting the zero point position. This actuator is widely used in the medical industry, measurement, laser welding, laser cutting, small CNC machine tools, engraving, milling machines, etc.
