Encoder E4 Miniature Optical Kit Encoder

Place housing (cover) on. With thumb and finger, squeeze ears together to insure that cover fully latches.

Slip codewheel onto shaft until it bottoms out against spacer tool. Spacer tool provides an air gap of 0.07" 0.03". Tighten set screw with either the hex wrench / hex driver while pressing down on codewheel.

Place spacer tool on optic module as shown below.

Transfer Adhesive:Peel off paper backing, place centering tool into center hole of base, slip entering tool onto shaft and slide base and centering tool down onto mounting surface as one piece. Press to form a good bond, then slip centering tool off shaft and continue with standard mounting instructions.

Place base onto shaft. Secure base to mounting surface using two screws.

Description: Hex wrench, .050" flat-to-flat for 3-48 or 4-48 set screws.

Description: Hex driver, .050" flat-to-flat for 3-48 or 4-48 set screws.

Description: This reusable tool is used to properly space the codewheel from the encoder base. Nylon. Round. Provides air gap of 0.07" to 0.03".

* See Ordering Information below for available Shaft Diameters.

Please note: A centering tool is highly recommended when using the T-option transfer adhesive.

Material: Aluminum.

Description: This reusable tool provides a simple method for accurately centering the E4 base onto the shaft.

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 (above) to position the base. T-option specifies transfer adhesive.

Provides alternate metric M2.5x.45mm, length 6mm screws. When M-option is NOT specified the default is #3-48 x 1/4" screws.

L-option To reduce the average power requirements, the L-option version of the E4P power can be strobed on just long enough to sample outputs A and B. This option is the same as our standard E4P, except the internal power bypass capacitor is not installed. The outputs settling time is typically 200 to 400 nano seconds after power up. The minimum sample frequency must be less than the maximum RPM X the CPR / 10.

The H-option adds a hole in the cover for the shaft to pass through:

For complete details see the page.

A leads B for clockwise shaft rotation, B leads A for counter clockwise shaft rotation viewed from the shaft/bushing side of the encoder (see the page).

* Includes axial play.
