Product Details

The Quantum Devices, Inc. Model QDH20 brings an enhanced feedback solution in applications typically using a standard size 20 package.

The QDH20 provides encoder feedback in conventional industrial mounting configurations, offering high-quality mechanical and environmental protection. Its outputs consist of a quadrature A & B with reference pulse Z as a standard feature, and the output can be configured with either a 5 to 26 volt OL7272 line driver or open collector outputs.

The QDH20 incorporates two heavy-duty bearings on the output shaft and two additional bearings along with a built-in flexible spring mount, effectively shielding the operational elements of the encoder from mechanical strains.
