Although standard socket head cap screws will work when mounting the E7P, to maximize clearance between the codewheel and the top of the screw head, we recommend low profile socket head cap screws when using the holes on the E7P board. Both standard or low profile socket head cap screws will work with the G-option.
0.750" Bolt Circle / Low Profile #4-40 x 1/4":
1.280" Bolt Circle / Low Profile #4-40 x 1/4":
1.280" Bolt Circle / #2-56 x 1/4" (2-option):
Provides two #2-56 x " screws in place of two #4-40 x 1/4".
1.812" Bolt Circle / #4-40 x 1/4" (G-option):
Provides mounting ears on the base allowing for a 1.812" bolt circle.
T-option: Transfer adhesive base
The T-option base provides a transfer adhesive
(with peel-off backing) that may be used when
mounting holes are not available. A centering
tool is required when using this option.
Compact (C-option) provides the lowest profile:
Cover Extension (E-option) provides space in the cover for longer shafts up to 0.836":
Hole in Cover (H-option) provides a 0.452" diameter hole in the cover for shafts:
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 E7P base to the shaft. A centering tool is highly recommended when using the T-option transfer adhesive.
2. Spacer Tool
A spacer tool is included for all packaging options.
Part #: SPACER-E7P
Description: This reusable tool is used to properly space the codewheel from the encoder.
