Quantum Devices, Inc. Model QD787 is intended for applications requiring high performance, high-resolution digital feedback in a very small package. The model QD787 provides 8 bit absolute resolution in a package only 20mm (0.787") in diameter. Outputs can be configured in either gray code or binary code. QDI's patent pending sensing scheme 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.
