QR145 optical incremental encoder provides an improved feedback solution in applications typically using modular encoders. Common options include 5-26V operation and IP66 sealed design.
Quantum Devices Model QR145 optical incremental encoder provides an improved feedback solution in applications typically using modular encoders. With an overall height of only 0.87” and the stability of a bearing encoder design, the model QR145 optical incremental 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 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. An optional IP66 housing is available at a fraction of the cost of competitors’ comparable sealed encoders.
