Two Channel High Resolution Optical Incremental Encoder Modules

HP => Agilent Technologies

Gap Setting for Rotary

and Linear Modules

Gap is the distance between the

image side of the codewheel and

the detector surface of the mod-

ule. This gap dimension must

always be met and codewheel

warp and shaft end play must stay

within this range. This dimension

is shown in Figure 1.

Mounting Considerations

for Rotary Modules

Figure 2 shows a mounting

tolerance requirement for proper

operation of the high resolution

rotary encoder modules. The

Aligning Recess Centers must be

located within a tolerance circle

of 0.13 mm (0.005 in.) radius

from the nominal locations. This

tolerance must be maintained

whether the module is mounted

with side A as the mounting plane

using aligning pins (see Figure 3),

or mounted with Side B as the

mounting plane using an

alignment tool.

Mounting with Aligning

Pins

The high resolution rotary

encoder modules can be mounted

using aligning pins on the motor

base. (Agilent does not provide

aligning pins.) For this configu-

ration, Side A must be used as the

mounting plane. The Aligning

Recess Centers must be located

within the 0.13 mm (0.005 in.) R

Tolerance Circle as explained

above. Figure 3 shows the

necessary dimensions.

Mounting with

Alignment Tools

Agilent offers alignment tools for

mounting Agilent encoder

modules in conjunction with

Agilent codewheels, using side B

as the mounting plane. Please

refer to the Agilent codewheel

data sheet for more information.
