A leads B for clockwise shaft rotation, B leads A for counter clockwise shaft rotation viewed from the cover/label side of the encoder.
H-option (Hole in Cover)
The H-option adds a hole in the cover for the shaft to pass through:
- For shaft diameters of 1.5mm to 1/8", a 0.170" hole is supplied.
- For shaft diameters of 5/32" and 4mm, a 0.295" hole is supplied.
L-option (Low Power Strobe)
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.
M-option (Metric Mounting Screws)
Provides alternate metric M2.5x.45mm, length 6mm screws. When M-option is NOT specified the default is #3-48 x 1/4" screws.
T-option (Transfer Adhesive)
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.
Part #: MCTOOL - (Shaft Diameter*)
Description: This reusable tool provides a simple method for accurately centering the E4 base onto the shaft.
Please note: A centering tool is highly recommended when using the T-option transfer adhesive.
* See Ordering Information below for available Shaft Diameters.
Part #: SPACER-4216
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".
