AEDR-8320 Series
(Reflective Surface Mount Optical Encoder)

Description

The AEDR-8320 encoder is an analog output encoder that employs optical reflective technology for rotary and linear movement control.

With the introduction of reflective technology, encoder packages can now be made smaller and weigh significantly lighter. This statement is better reflected in the ability of the AEDR-8320 encoder which can easily fit into many space and weight constraint applications, e.g., CD or DVD writer laser head’s linear movement.

The AEDR-8320 comes in a 180 LPI (Lines Per Inch) or 7.09 mm lines per mm. In addition its 2-channel analog outputs can obtain higher resolution through interpolation of 2x, 4x, 8x or more. For example, with 8x interpolation, the final resolution of the encoder will yield 1,440 lines per inch, which is approximately 20 μm accuracy.

AEDR-8320 encoder enhances design flexibility and provides an easy-to-assemble solution to a wide variety of applications, while continuously ensuring reliability in performance.
