May 29, 2007 - QR12 with 1.280 Bolt Circle Mounting Flange, the new compact encoder by Quantum Devices, Inc., provides increased versatility and improved feedback for applications typically using modular encoders. With a smaller OD (1.2 inches), an overall height of just over an inch and the stability of a bearing encoder design, the QR12 can provide significant performance upgrades in applications limited by traditional modular encoder solutions.
Outputs consist of a quadrature with index pulse, and three-phase commutation. A flexible member allows for much greater tail shaft run-out than can be tolerated by modular encoder designs, plus it provides 30 degrees of rotation for commutation timing, providing the performance of a lightweight robust assembly.
