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
