DIMENSIONS AND PINOUTS
To order an single-ended encoder without index, add a “ - ”, the CP\
R number, and an SN on the 
end of any Anaheim Automation dual shaft motor. 
L010391
23Y106D-LW8-1000SN
The part number for a 1000 CPR encoder mounted on a 23Y106D-LW8 stepper  
motor would be 23Y106D-LW8-1000SN.
Example: 
Single-Ended Encoder without Index Channel
New Optical Encoder Module:
This new transmissive optical encoder module was designed to be an improved replacement for the Avago 
HEDS-9000 series encoder module. This module is designed to detect rotary position when used with a 
code wheel. The new module consists of a lensed LED source and a monolithic detector IC enclosed in a 
small polymer package. The new module uses phased array detector technology to provide superior 
performance and greater tolerances over traditional aperture mask type encoders. The new module 
provides digital A & B quadrature outputs with an optional third output index channel. Each module is 
resolution specific and is matched to the resolution of a code wheel. All standard resolutions offered by the 
HEDS-9000 series encoder module, as well as additional resolutions, are now supported by the new module. 
The new module operates with a single 5V supply and provides single ended outputs which are capable of 
both sinking and sourcing 8mA at TTL levels. An internal 0.1 uF decoupling capacitor is designed into the 
new module to provide enhanced noise immunity over the HEDS-9000 series encoder modules. Physically , 
the new module has no external wire loops which can interfere when mounting. The connector pins are 
0.051” shorter than HEDS modules, while still providing .30” insertion depth. 
When a Single-Ended Encoder without Index is attached to the end of an Anaheim Automation dual shaft 
motor, it provides digital output information for applications that require position, speed or direction control.

ELECTRICAL SPECIFICATIONS
Model #Description
CPR(N):The Number of Cycles Per Revolution
One Shaft Rotation:360 mechanical degrees, N cycles
One Electrical Degree (°e):1/360th of one cycle
One Cycle (C):360 electrical degrees (°e). Each cycle can be decoded into 1 or 4 codes, referred to as X1 or X4 resolution multiplication
Symmetry:A measure of the relationship between (X) and (Y) in electrical degrees, nominally 180 °e
Quadrature (Z):The phase lag or lead between channels A and B in electrical degrees, nominally 90 °e
Index (CH I):
The Index Output goes high once per revolution, coincident with the low states of channels A and B, nominally 1/4 of one cycle (90°e)
