Quantum Devices, Inc. Model QD200 Optical Encoder provides an improved rotary encoder feedback solution in applications typically using modular encoders. With an overall length of 0.93” and the stability of a bearing encoder design, the model QD200 Optical Encoder can provide significant performance upgrades in applications limited by traditional modular encoder solutions.
Outputs consist of a quadrature with reference pulse and three-phase commutation, which can be configured with either the industrial standard 5 volt RS422A Line Driver or the 5 to 26 volt OL7272 line driver. A flexible spring mount 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. A housing constructed of conductive carbon fiber composite provides the EMI shielding of an all metal housing and the performance.
