Product Details

Quantum Devices, Inc.'s QD145 Optical Encoder offers an advanced feedback solution, perfect for applications typically reliant on modular encoders. With an impressively slim height of 0.87" and the stability of a bearing encoder design, the QD145 model is capable of delivering noteworthy performance improvements in scenarios usually limited by standard modular encoder solutions.

Its outputs comprise a quadrature with reference pulse and three-phase commutation, which can be tailored to either the industry-standard 5 volt RS422A Line Driver or the adaptable 5 to 26 volt OL7272 line driver. A flexible member allows for significantly greater tail shaft run out than modular encoder designs usually permit, along with providing 30 degrees of rotation for commutation timing. Its housing, constructed from conductive carbon fiber composite, offers the EMI shielding typically associated with an all-metal housing while maintaining the advantages of a lightweight and sturdy assembly.
