Description:
The E3 offers twice the resolution of our E2 series. It fits all the shaft diameters of our E2 series, plus 12mm, 1/2", 3/4", 14mm, 5/8", and 1". Additional diameters may be systematic a l l y added. The E3 optical kit encoder is a non-contacting, rotary to digital position feedback device designed to easily mount to and dismount from an existing shaft. The internal monolithic electronic module converts the real-time shaft angle, speed, and direction into TTLcompatible outputs. Simplicity and low cost make the E3 ideal for both high and low volume motion control applications. The E3 consists of four parts: base, cover, hub/code wheel, and encoder module. The base provides mounting holes for: 2 (2-56 or 4-40) screws in a .750" bolt circle, 3 (080) screws in a .823" bolt circle, 2 (4-40) screws in a 1.280" bolt circle, and 2 (4-40) screws in a 1.812" bolt circle. For shaft diameters less than .5", the base comes with a .44" hole; for all larger shaft sizes, the hole diameter is 1.44" and only the mounting holes in a 1.812" bolt circle remain. The base and housing are made of reinforced glass polycarbonate. The cover is available in three configurations; the standard is a solid flush back which can accommodate a shaft length up to .53". An optional hole in the back with .55" or 1.05" diameter can be specified for the shaft to pass through. The hub/code wheel is available in diameters up to 1". A list of standard diameters can be found on the page 4 of this data sheet. Standard diameters are stocked. There is a quick turn around time for most special diameters. The encoder module incorporates a lensed LED light source and monolithic photodetector array with signal shaping electronics to produce the two channel bounceless TTL outputs.
and workmanship for two years. See complete warranty for details.

3-option:
3-option makes all five of these hole diameters .125".
Optical Kit Encoder
E-option:
The E-option provides a cylindrical extension to the housing cover allowing for longer shafts of up to .670". This option is only for shaft diameters <.472".
H-option:
The H-option adds a hole to the housing for the shaft to pass through.
Ø Shafts =1/2", a 1.05" diameter hole is supplied.
T-option:
W h e n 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 a d h e s i v e on the standard mounting base. Instructions: To use transfer adhesive, peel off paper backing and slip tool into center hole of base and slide both down shaft as one piece. Press to form a good bond, then slip tool off and continue with standard mounting instructions. A centering tool is highly recommended when using this option.
M-option:
These adapter plates are for mounting to a 3" diameter bolt circle. Use two 4-40 x 1/4" screws (sold separately) to attach the E3 base to the plate. Comes attached when ordered with encoder (see options below).

Disk Optics:
Be sure to keep different diameters, resolutions and options separated. The resolution of the optoelectronic modules and the code wheels must match. Index and non-index parts cannot be mixed since the optical patterns are different. An additional identifier is stamped on each optoelectronic module. The 2-channel (non-index) version can be identified by a number 9000 or 9100. A 9040 or 9140 identifies the 3-channel (index) version. One letter stamped on each module specifies the resolution as shown in the adjacent table. * US Digital's EM1 optical encoder module. 1 stands for 1" disk, while the second number set is the resolution.
