These modules are designed to detect rotary position with a codewheel when added to the end of an Anaheim Automation dual shaft motor. These differential encoders consist of a lensed LED source and a monolithic detector IC enclosed in a small polymer package. These modules use phased array detector technology to provide superior performance and greater tolerances over traditional aperture mask type encoders. They provide digital quadrature differential outputs on all resolutions. These encoders are powered from a single +5VDC power supply. L010386 To order an differential encoder without index, add a “ - ”, the CP\ R number, and a DN on the end of any Anaheim Automation dual shaft motor. 23Y106D-LW8-0400DN The part number for a 400 CPR encoder mounted on a 23Y106D-LW8 stepper motor would be 23Y106D-LW8-0400DN.

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)
