Encoders, Hollow Shaft
2.00" Diameter Optical Encoder
Quantum Devices, Inc. Model QD200 provides and improved feedback solution in applications typically using modulars encoders. With an overall length of 0.93" and the stability of a bearing encoder design, the model QD200 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 of a lightweight robust assembly.
