5 V motor A16B-31

coreless

Overview
Coreless motors A16B series (outer diameter φ16 mm). The A16B series includes multiple sub-models (examples: A16B-33, A16B-31, A16B-29, A16B-27, A16B-25, A16B-22, A16B-10, A16B-09, A16B-07, A16B-04, A16B-03). Sub-model A16B-33 is listed as a representative sub-model used in applications such as electronic locks (security doors). Product pages provide detailed specifications for each sub-model and offer outline drawings and CAD data for download.
