with encoder

Helix Linear Technologies' NEMA 8 Single Stack Captive Lead Screw Stepper Motor Actuators with 500 CPR encoder integrate a NEMA 8 single stack bipolar stepper motor with a miniature 0.125 inch diameter lead screw and built-in anti-rotation guide for closed-loop, high-accuracy controlled stroke linear motion in the smallest available footprint. Available across multiple fine lead options and short stroke lengths for medical devices, optical systems, lab automation, semiconductor, and micro-precision positioning applications requiring position feedback. U.S.-made.
