Product Details

Quantum Devices, Inc.'s Model QR12 offers an enhanced feedback solution in applications usually powered by modular encoders. With a total height of less than one inch and the reliability of a bearing encoder design, the QR12 model can significantly upgrade performance in applications constrained by standard modular encoder solutions.

QR12's outputs comprise two incremental quadrature channels, an index pulse, and three-phase commutation.

The design also includes a flexible spring steel mount that allows for more tail shaft run out and TIR than can be accepted by modular encoder designs, while providing 30 degrees of rotation for commutation timing.
