HEDS
Optical Encoder Module
This optical encoder incremental module is used to detect a linear or
rotary position when used together with a codewheel. Each module
consists of a lensed LED source and a monolithic detector IC enclosed
in a small plastic package. They are available in 2 channel or 3 channel
versions. The resolution and index version of the modules and
codewheels must match. They can easily be mounted by using 4-40
screws through the mounting holes. These devices are very reliable
when connected properly. Improper connections are the most common
cause of failure. For maximum noise immunity or cables longer than 6
feet, add a
cable driver option (
PC4, EA-D8
). For open collector or higher
voltage applications, add the
PC3
device. The suggested mating
connector can be found on each encoder's product data sheet, or on
the
Cables & Connectors
data sheet. Codewheels, quadrature
decoder chips, counter chips, computer interface boards, mating
connectors and mating cables are also available.
Agilent announced recently that they will discontinue a number of their
optical encoder module resolutions and associated encoders. Some of
these discontinued resolutions, plus additional resolutions, are readily
available from US Digital. For further information on our own incremental
optical encoder module, please see the
EM1
data sheet.

Optical Encoder Module
Timing Diagram:
CPR (N):
The number of Cycles Per Revolution.
One Shaft Rotation:
360 mechanical degrees, N cycles.
One Electrical Degree (°e):
1/360 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).
Position error:
The difference between the actual shaft position and the position indicated by the encoder cycle count.
Cycle error:
An indication of cycle uniformity. The difference between an observed shaft angle which gives rise to one electrical cycle, and the nominal
angular increment of 1/N of a revolution.
Shaft Rotation for Shaft Encoders:
Ø
View the encoder so the shaft/bushing side is facing up.
