Quantum Devices Inc. Model QDH20 provides an improved feedback solution in applications typically using a standard size 20 package.  The QDH20 provides encoder feedback in standard industrial mounting configurations with superb 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 heavy-duty bearing sets holding the output shaft … and two more bearings along with an integral flexible spring mount to isolate the working pieces of the encoder from mechanical stresses. Other 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-in. shaft diameter
• High Noise Immunity
