Same Sky NEMA08 to NEMA23 AMT112S Stepper Motors
Same Sky NEMA08 through NEMA23 AMT112S assemblies combine a LIN Engineering bipolar stepper motor with a Same Sky capacitive incremental encoder. The encoder supports programmable quadrature resolution and a digitally aligned index. These are motor-and-feedback assemblies: a suitable external drive and controller are still needed to create a closed-loop motion system.

Applications and Industries
Consider these assemblies for compact OEM positioning, indexing, dosing or inspection mechanisms where a bipolar stepper and incremental shaft feedback fit the machine architecture. These are engineering selection possibilities; the motor datasheets do not establish a certified application or a complete robot joint.
Industrial automation
Review Summary
Consider this range for an OEM axis that needs a compact stepper with accessible incremental feedback and a choice of motor sizes or windings. Its useful distinction is the packaged encoder, rather than an integrated amplifier. Select the exact model by its loaded torque-speed curve, phase current and mechanics; neither holding torque nor 4096 PPR establishes machine positioning accuracy.
