Quantum Devices, Inc. Model QR12 provides an improved feedback solution in applications traditionally using modular encoders. With an overall height of less than one inch and the stability of a bearing encoder design, the model QR12 can provide significant performance upgrades in applications limited by modular encoder solutions.
Outputs consist of two incremental quadrature channels with an index pulse and three-phase commutation.
A flexible spring steel mount allows for much greater tail shaft run out and TIR than can be tolerated by modular encoder designs, while also providing 30 degrees of rotation for commutation timing.
