Magnetic Encoder 1000PPR Integrated Stepper, 16Ncm – Ultra_Slim Nema 17 Closed_loop Design

Product Overview

This is the thinnest closed-loop stepper motor in our lineup, with a compact 26mm body length including the encoder. It integrates a 1000PPR (4000CPR) magnetic incremental encoder with 3-channel differential output. Magnetic encoders offer a smaller footprint and better cost-performance than optical types, making them ideal for space-constrained applications that still demand reliable feedback control.
