Encoder Orientation
The AEDR-8400 is designed such that both the emitter
and detector IC should be placed parallel to the win-
dow/bar orientation, as shown. As such, the encoder is
tolerant against radial play of ± 0.20mm.
Direction of Movement
With the emitter side of the encoder placed closer to the
codewheel centre, Channel A leads Channel B when the
codewheel rotates anti-clockwise and vice versa.
