Electric actuator DSM42

linearlead screwstepper

Overview
Based on DINGS platform products, the DSM 42 mm series combines a precision lead-screw linear actuator and a self-developed simple linear module into a compact, reliable linear solution. DSM42 offers precise positioning, a wide range of optional stroke lengths and multiple lead screw options for tailored integrated solutions.
