QR12 Series Incremental Encoders
QR12 optical encoder delivers improved feedback over modular encoders in a sub-one-inch package. Its bearing design boosts performance, with quadrature incremental outputs, index pulse, and three-phase commutation. A spring steel flex mount accommodates greater shaft runout and enables 30° commutation
