The 20M020D2B is a 20 mm diameter can stack stepper motor designed for precise open-loop positioning, with a bipolar winding configuration. It operates at 12 VDC with a rated current of 0.10 A per phase, a resistance of 115.2 Ω per phase, and an inductance of 52.8 mH per phase. It delivers a minimum holding torque of 11.0 mNm (1.56 oz-in) and has a step angle of 18.0 degrees, resulting in 20 steps per revolution. The motor has a rotor inertia of 0.41 gcm², a detent torque of 3.53 mNm, and operates within an ambient temperature range of -20 to +70 °C. It uses a sintered bronze sleeve bearing and has a weight of 23.5 g. The leadwires are AWG 28, UL 1429 rated. This part is RoHS compliant.
