New Industrial Grade Optical Encoder from Quantum Devices

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.

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
• High Noise Immunity
