• Description: Two Channel High Resolution Optical Incremental Encoder Modules
• Manufacturer: HP [Agilent(Hewlett-Packard)]

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. (HP does not provide align-
ing pins.) For this configuration,
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 HP
Alignment Tools
HP offers alignment tools for
mounting HP encoder modules in
conjunction with HP codewheels,
using side B as the mounting
plane. Please refer to the HP
codewheel data sheet for more
information.
