(1) Position inaccuracy is proportional to shaft radial play.
(2) 60000 rpm is the maximum rpm due to mechanical considerations. The maximum rpm due to the module's 300kHz maximum count frequency is (18 x 10^6) / CPR.
(3) Only for shaft diameters < 0.472".
(4) Add 0.125" to all required shaft lengths when using M-option.
A leads B for clockwise shaft rotation, and B leads A for counterclockwise rotation viewed from the cover/label side of the encoder.

The E-option provides a cylindrical extention to the cover allowing for longer shafts of up to .750".
Please note: Only available for shaft diameters <.472".
View option:


H-option
The H-option adds a hole to the cover for the shaft to pass through.
- Shafts 2mm to 10mm, a .438" diameter hole is supplied.
- Shafts 12mm to 1", a 1.047" diameter hole is supplied.
View option:


L-option
Provides Avago / Agilent / HP differential compatible pin-out. See direct replacement information above.
Please note: Only available for E6D and E6MD (10-pin versions).
M-option
This adapter plate is for mounting to a 3" diameter bolt circle. Use two 4-40 x 1/4" screws (sold separately) to attach the E6D base to the plate. Comes attached when ordered with encoder.
View option:

T-option
When mounting holes are not available, a pre-applied transfer adhesive (with peel-off backing) is available for stick-on mounting. Use the centering tool (sold separately) to slide the base into position. T-option specifies transfer adhesive on the standard mounting base.

For Shafts Less Than Or Equal To 0.394" (10mm)
-
1. Base Mounting
Secure the
base to the mounting surface using two or three screws. If
a centering tool is used, slip it over the shaft and into
the center hole of the base. Tighten mounting screws.
Remove centering tool.
-
2. Spacer Installation
Place spacer tool on optic module as shown below.
-
3. Codewheel Installation
Slip codewheel over shaft with mylar disk towards top
until it bottoms out against the spacer tool. Tighten set
screw with hex wrench provided while pressing down on
hub.
-
4. Encoder Module Installation
Slip optical module into position until two alignment
pins slip into holes of module (thick side of module
towards bottom). Secure with 4-40 x 1/2" screws
(supplied).
-
5. Cover Installation
Place housing (cover) over assembly and secure with
two 4-40 x 5/8" cover screws (supplied).
For Shafts Greater Than 0.394" (10mm):
-
1. Base Mounting
Secure the
base to the mounting surface using two or three screws. If
a centering tool is used, slip it over the shaft and into
the center hole of the base. Tighten mounting screws.
Remove centering tool.
-
2. Spacer Installation
Place spacer tool on optic module as shown below.
-
3. Codewheel Installation
Slip codewheel over shaft with mylar disk towards top
until it bottoms out against the spacer tool. Tighten set
screw with hex wrench provided while pressing down on
hub.
-
4. Encoder Module Installation
Slip optical module into position until two alignment
pins slip into holes of module (thick side of module
towards bottom). Secure with 4-40 x 1/2" screws
(supplied).
-
5. Cover Installation
Place housing (cover) over assembly and secure with
two 4-40 x 5/8" cover screws (supplied).
Please note:
- Shown using the Differential version
- These instructions are compatible for all versions of the E6.
1. Centering Tool
The centering tool is only included with the -3 packaging option. It has to be ordered separately for other packaging options.
Part #: CTOOL - (Shaft Diameter)
Description: This reusable tool provides a simple method for accurately centering the E6 base onto the shaft. It is recommended for the following situations:
- When using mounting screws smaller than #4-40.
- When the position of the mounting holes is in question.
- When using the 3-hole mounting pattern.
- When using the T-option transfer adhesive.
Instructions: When mounting encoder base, slide centering tool down shaft until it slips into centering hole of encoder base. Tighten mounting screws, then remove centering tool.
2. Hex Tool
Depending on the order packaging option, either a hex driver or hex wrench is included.
Part #: HEXD-050
Description: Hex driver, .050" flat-to-flat for #3-48 or #4-48 set screws. Only included with -B or -1 packaging options.
Part #: HEXW-050
Description: Hex wrench, .050" flat-to-flat for #3-48 or #4-48 set screws. Only included with -2 or -3 packaging options.
3. Spacer Tool
A spacer tool is included for all packaging options.
Part #: SPACER-265
Description: For shaft sizes < 0.472"
Part #: SPACER-555
Description: For shaft sizes 12mm to 1"
4. Screws
Screws for base mounting must be purchased separately. Screws for mounting the housing to the base are included.
Part #: SCREW-080-250-PH
Description: Pan Head, Cross Drive #0-80 UNF x 1/4"
Quantity Required for Mounting: 3 per encoder
Part #: SCREW-256-250-PH
Description: Pan Head, Cross Drive #2-56 UNC x 1/4"
Quantity Required for Mounting: 2 per encoder
