(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 maximum frequency response is dependent upon the module’s resolution (CPR). For resolutions of 32 to 1999 CPR the frequency response is 300 kHz, 2000 to 3999 CPR the frequency response is 360 kHz and 4000 CPR and greater the frequency response is 720 kHz
(3) Add 0.125" to the required shaft length when using R-option.
(4) Including Axial play.
B leads A for clockwise shaft rotation, and A leads B for counterclockwise rotation viewed from the cover/label side of the encoder.

1. Centering Tool
Part #: CTOOL - (Shaft Diameter)
Description: This reusable tool provides a simple method for accurately centering the E2 base onto the shaft, promoting hub to base concentricity and thus accuracy. 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.
2. Hex Tool
Depending on the order packaging option, either a hex driver or hex wrench is included.
Part #: HEXD-050 (only included with -B or -1 packaging options)
Description: Hex driver, 0.050" flat-to-flat for #4-48 set screws.
3. Spacer Tool
A spacer tool is included for all packaging options.
Part #: SPACER-E2
4. Screws
Screws for base mounting must be purchased separately. Screws for mounting the housing to the base are included.
