The 20DBM-K series are 20 mm diameter captive stepper linear actuators with a 20 mm stroke and up to 50 N holding force. The 20DBM20D4B-K variant is a bipolar motor with 1.41 A rated current, 1.4 Ω phase resistance, and 1.4 VDC operating voltage, designed for microstepping. It provides 48 steps per revolution, ±1 step accuracy, and operates from -20°C to +70°C with a maximum coil temperature of 130°C. Ball bearings support load repeatability, and the unit is RoHS compliant. Electrical parameters vary across the series; this model shares housing, bearing, and compliance specifications with its siblings. The exact part number 20DBM20D4B-K is not printed, but its base form 20DBM20D4B is matched by the D4B bipolar variant's data.
20DBM-K Linear Actuator Stepper Motor
20DBM-K
The 20DBM-K high resolution captive stepper linear actuators are tailored for demanding applications that need smaller move increments and finer positioning.With 7.5 deg step angle,these linear actuators can deliver a high linear force up to 50N. Larger ball bearings with proprietary pending pre-load design support higher load capacity & repeatability.
