May 10, 2017 - Quantum Devices Model QDH20 provides a feedback solution in applications typically using a standard size 20 package. The QDH20 provides encoder feedback in standard industrial mounting configurations with mechanical and environmental protection. Outputs consist of a quadrature A & B with reference pulse Z as a standard feature. The output can be configured with either the industrial standard 5 to 26 volt OL7272 line driver or open collector outputs. The QDH20 features two bearing sets holding the output shaft, and two more bearings along with a spring mount to isolate the working pieces of the encoder from mechanical stresses.
Features include: • 500 kHz Fundamental Frequency Response • High Operating Temperature Option (100 C) • Resolutions up to 5000 lines per revolution direct read • Flange and Servo Mount Options • 0.375" shaft diameter
