... AEDR-8320 encoder which can easily fit into many space and weight constraint applications, e.g 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 interpola- tion of 2x, 4x more ...

... When used with a codewheel or linear codestrip, the encoder translates rotary or linear motion into analog outputs. As shown in the block diagram below, the AEDR-8320 encoder consists of three major components: a light emitting diode (LED) light source, a detector IC consist- ing photodiodes and lens to focus light beam from the emitter as well as light falling on the detector ...

... Encoder Orientation The AEDR-8320 is designed such that both the LED and detector IC should be placed parallel to the window/bar orientation, as shown. As such, the encoder is tolerant against radial play of ± 0.20 mm. The emitter side should be placed closer to the rotating shaft. Mounting Consideration R OP < ∞ ...
