... The AEDR-8300-1Wx offers two-channel quadrature digital outputs. Being TTL compatible, the outputs of the AEDR-8300-1Wx can be interfaced directly with most of the signal processing circuitries. Hence the encoder provides great design-in flexibility and easy integration into existing systems. The AEDR-8300-1Wx could yields encoding resolution at 212 lines per inch (LPI) which is 8 ...

... When used with a codewheel or linear codestrip, the encoder translates rotary or linear motion into digital outputs. As seen in the block diagram, the AEDR-8300- 1Wx consists of three major components: a light emitting diode (LED) light source, a detector IC consisting photodiodes and lens to focus light beam from the emitter as well as light falling on the detector ...

... Ch B Encoder Orientation The AEDR-8300-1Wx 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 ± 0.38mm. The emitter side (pins 3 and 4) should be placed closer to the rotating shaft. ...
