Orientation of Artwork
for HEDS-9040 Option
T00 (2000 CPR, 23.36
mm Rop)
The Index area on the HEDS-
9040 Option T00, 2000 CPR
Encoder Module has a non-
symmetrical pattern as does the
mating Codewheel. In order for
the Index to operate, the "Right-
reading" side of the Codewheel
disk (the “Artwork Side”) must
point toward “Side A” of the
Module (the side with the
connecting pins).
Because the Encoder Module may
be used with either “Side A” or
with “Side B” toward the
Mounting Surface, Agilent
supplies two versions of Film
Codewheels for use with the
Option T00 3-channel Module:
Codewheel HEDM-6140 Option
TXX has the Artwork Side on the
“Hub Side” of the Codewheel/hub
assembly and works with “Side B”
of the Module on the user’s
mounting surface. Codewheel
HEDM-6141 Option TXX has the
Artwork Side opposite the
“Hub Side” and works with “Side
A” of the Module on the mounting
surface. For the Index to operate,
these parts must be oriented as
shown in Figure 7a and 7b.
