Optical Feedback 1000PPR Encoder Integrated Stepper, 0.06Nm – Nema 11 Closed_loop Short Shaft Design

Product Overview

This Nema 11 closed-loop stepper motor integrates a high-resolution 1000PPR (4000CPR) optical incremental encoder to deliver precise positioning and real-time feedback. With a holding torque of 0.06Nm (8.5oz.in), rated current of 1.0A, and a compact 10mm shaft, it provides enhanced accuracy, improved torque, and lower thermal output compared to open-loop stepper motors. Ideal for compact precision systems in automation, robotics, and instrumentation.
