The 20DBM-L is a Ø20 mm bipolar stepper linear actuator designed for precise linear motion in applications requiring high resolution and repeatability. It features a 50 mm stroke length, 48 steps per revolution, and ball bearings for enhanced load capacity. The 20DBM10D4B-L 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 minimum holding force of 35 N at rated current and 13.9 N when unenergized. It supports an operating temperature range of -20 to +70 °C, with a maximum coil temperature of 130 °C. The actuator is RoHS compliant, weighs 35 g, and has a dielectric withstanding voltage of 650 VAC for 2 seconds. Linear travel accuracy is ±1 step, and insulation resistance is 20 Mohms at 500 VDC.

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.
