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 confi gurations 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 confi gured with either the 5 to 26 volt OL7272 line driver or open collector outputs.
The QDH20 features two heavy-duty bearings 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.
