Quantum Devices, Inc. Model QD145 was designed to provide an improved feedback solution in applications typically using modular encoders. With an over all length of just only 0.87" and the stability of a bearing encoder design, the model QD145 can provide significant performance upgrades in applications limited by traditional modular encoder solutions.

Outputs consist of 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 member allows for much greater tail shaft run out than can be tolerated by modular encoder designs plus 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 performance of a lightweight robust assembly.
