DC motor A12C-30

3.7 Vcorelessfor medical applications

Overview
The A12C series of coreless motors by C.I. TAKIRON is a family of φ12.4 mm outer-diameter coreless motors offered in multiple length and performance variants for applications such as dental handpieces (A12C-30), single-lens reflex cameras (A12C-31), surveillance cameras (A12C-20) and other precision devices. The series includes numerous sub-models (A12C-xx) with differing lengths, applied voltages, terminal resistances and performance characteristics. Product pages for individual sub-models provide high-resolution images, gallery thumbnails and demonstration videos.
