About QR110 Optical Rotary Encoder

Quantum Devices, Inc. Model QR110 Optical Rotary Encoder is designed to provide high resolution digital feedback in an industrial standard size 11 mounting format. Quadrature with reference pulse output format, resolutions up to 2048 lines per revolution (direct read) and a variety of electrical options are easily capable of satisfying the most demanding feedback application. The QR110 provides the user digital position information, directly from the feedback device, without the external R to D converters that are typically used with resolver feedback. Converting from size 11 resolver to encoder feedback is easily accomplished with the QR110 without the need for costly mounting modification to existing designs. QDI’s unique optical sensing system embodies a much simplified encoder design, which ultimately results in longer service life and less down time due to feedback device failure. The encoder housing is constructed of a conductive carbon fiber composite that provides the EMI shielding of an all-metal housing and performance of a lightweight robust assembly.

Design Features:

• Standard size 11 encoder mounting
• Compatible with size 11 resolver mounting
• Resolutions up to 2048 lines per revolution direct read
• Unique optical sensing system
• Differential and single ended outputs
• Nickel coated carbon fiber housing
• IP50 sealing
• High noise immunity
• Low supply current requirements
• RoHS construction

Note: prior to transitioning to RoHS Compliance, the product name was QD110 rather than QR110. Therefore, when cross-referencing a QD110 configuration, simply substitute the configuration prefix with QR110.
