DC motor A16B-09

12 Vcorelesscompact

Series
A16B coreless motor series (outer diameter φ16 mm).

Overview
Coreless DC motors in a compact φ16 mm form factor. Multiple sub-models are available (examples: A16B-33, A16B-31, A16B-29, A16B-27, A16B-25, A16B-22, A16B-10, A16B-09, A16B-07, A16B-04, A16B-03). Typical applications include electronic locks (security doors) and other compact drive applications where small diameter and varied voltage options are required.
