Orientation of Artwork for HEDS-9040 Option T00 (2000 CPR, 23.36mm Rop) and HEDS-9140 Option B00

(1000CPR, 11.00mm Rop)

*Please note that the image side of the codewheel must always be facing the module Side A.

The Index area on the HEDS- 9040 Option T00, 2000 CPR

and HEDS-9140 Option B00, 1000 CPR Encoder Module

has a nonsymmetrical pattern as does the mating Code-

wheel. In order for the Index to operate, the “Rightread-

ing”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, Avago supplies two versions of Film

Codewheels for use with the Option T00 3-channel

Module and Option B00 3-Channel Module: Codewheel

HEDM-6140 Option TXX and HEDM-5040 Option Bxx 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 and HEDM-5041-Bxx has the Artwork Side

opposite the “Hub Side” and works with “Side A” of the

Module on the mounting surface. For the Index to oper-

ate, these parts must be oriented as shown in Figure 7a

and 7b.
