QR200 Spec Sheet

ABOUT QR200 OPTICAL ROTARY ENCODER

Quantum Devices Model QR200 incremental rotary 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, model QR200 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 RS-422 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.
