DC motor A12C-36

6 Vcorelessfor medical applications

Overview
The A12C series of coreless motors from C.I. TAKIRON Corporation. Outer diameter φ12.4 mm. The page lists multiple sub-models optimized for different applications (examples: A12C-30 used in dental treatment devices, A12C-31 in single-lens reflex cameras, A12C-20 in surveillance cameras). The series offers a wide range of applied voltages, terminal resistances, speeds and torques. Customizable items: gear head, lead pin, lead wire, grounding terminal.

Applications (examples)

• Dental treatment devices (e.g. A12C-30)
• Single-lens reflex cameras / optics (e.g. A12C-31)
• Surveillance / security cameras (e.g. A12C-20)
