no encoder

Helix Linear Technologies' BSA-14-E Single Stack Threaded Ball Screw Stepper Motor Actuators without encoder integrate a NEMA 14 single stack bipolar stepper motor with a precision 8 mm diameter ball screw and threaded ball nut for accurate open-loop linear motion in an ultra-compact, low-profile form factor. Available in 5 mm and 8 mm lead options with optional 8N end machining for robotics, medical devices, semiconductor, and space-constrained automation applications where open-loop position control is sufficient. U.S.-made.
