20DBM-L series linear actuators are compact stepper motors designed for precision positioning with a 20 mm diameter and 50 mm stroke length. The D4B bipolar variant operates at 1.4 VDC with a phase resistance of 1.4 ohms and a rated current of 1.41 A per phase, delivering a maximum holding force of 22 N at 0.0508 mm stroke. It has a step angle of 7.5 degrees (48 steps per revolution), a ball bearing design, and operates from -20°C to +70°C. Maximum coil temperature is 130°C, weight is 35 g, and insulation resistance is 20 Mohms at 500 VDC. The unit meets RoHS compliance.

20DBM-L
The 20DBM-L high resolution non captive stepper linear actuators are tailored for demanding applications that need smaller move increments and finer positioning. With 7.5 deg step angle, these high power 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.
