DC motor A12C-33

3 Vcorelesscustom

Overview
The A12C series are coreless DC motors with an outer diameter of 12.4 mm and a range of lengths and electrical ratings across sub-models. Sub-models are used in applications such as dental treatment devices (example: A12C-30), single-lens reflex cameras (example: A12C-31) and surveillance cameras (example: A12C-20). Detailed electrical/mechanical data, external drawings and CAD files are provided per sub-model.
