with encoder

Helix Linear Technologies' BSA-8-E Single Stack Threaded Ball Screw Stepper Motor Actuators with 1000 CPR encoder integrate a NEMA 8 single stack bipolar stepper motor with precision 4 mm and 5 mm diameter ball screws and a threaded ball nut for closed-loop, high-accuracy linear motion in an ultra-miniature, low-profile footprint. Available in 1, 2, and 3 mm lead options with optional 8N end machining for miniature robotics, medical devices, optical systems, semiconductor, and micro-precision automation applications requiring position feedback. U.S.-made.
