QD12 compact encoder from Quantum Devices Inc. provides improved feedback for applications that typically use modular encoders. Device features a small O.D. (1.2 in.), an overall height of just over an inch, and the stability of a bearing encoder design. It is said to offer significant performance upgrades in applications limited by traditional modular encoders. Outputs consist of a quadrature with index pulse and three-phase commutation. A flexible member reportedly allows for much greater tail shaft runout than can be tolerated by modular encoder designs. It also provides 30° rotation for commutation timing to provide the performance of a lightweight robust assembly. www.quantumdev.com
