Product Details

Quantum Devices, Inc.'s QD145 Optical Encoder is an advanced feedback solution designed for applications traditionally using modular encoders. With a mere height of 0.87" and the stability of a bearing encoder design, the QD145 model can contribute significantly to enhancing performance in applications that are limited by conventional modular encoder solutions.

It offers output configurations of a quadrature with reference pulse and three-phase commutation, which can be set up with either the industry-standard 5 volt RS422A Line Driver or the flexible 5 to 26 volt OL7272 line driver. The flexible member can accommodate a far larger tail shaft run out than what can be tolerated by modular encoder designs, while also providing 30 degrees of rotation for commutation timing. The conductive carbon fiber composite housing provides the EMI shielding you'd expect from an all-metal housing, while ensuring the benefits of a lightweight and robust assembly.
