All encoders have the following electrical features:

• Common
• Output Signal(s)

power should be regulated to within ±5% at the en-
coder and should be free of induced transients. Com-
mon (also referred to as Com, supply common, and
ground) is generally a black wire (verify via Electrical
Connections table). Common should always be con-
nected to the negative (-) side of DC power.
All encoders have at least one output signal (A); how-
ever, it is common for encoders to have three signals
A, B, Z (may also be referred to as C, X, or index).
The outputs should each be connected to the receiv-
ing device at the appropriate terminal. NOTE: Never
connect A, B, or Z to the + or - side of DC power.

 The use of shielded cable is recommended
for all encoder installations. When a Dynapar brand
encoder is ordered, the type of termination is gener-
ally defined (usually the last selectable code in Order-
ing Information). If a code for a cable was indicated,
the encoder was manufactured to include a shielded
cable. If any other type of termination was selected or
if selection of termi-nation type was not requested, a
cable assembly must be ordered. (The cable assem-
bly easily hooks onto the encoder’s connector making
it ready for wiring).
To determine which cable assembly to order, refer
to the Electrical Connections table (in the encoder’s
manual).

Encoders provide quality measurements and long
life when common sense, care, and accurate align-
ments are provided during installation. The following
general guide-lines will help to ensure a trouble-free
installation.

• Never connect or disconnect the encoder con-
nector or wiring while power is ON. Doing so may
damage the encoder.
• Power should always be connected to the + side
of DC power.
• Common should always be connected to the -
side of DC power.
• Never connect A, B, or Z to the + or - side of DC
power.
In some cases, there may be more than one table or
the table may be broken into sections due to different
output types. If so, refer to the information listed for
the output type selected for the encoder (in Ordering
Information).
Wiring should be run through dedicated conduits or
harnesses (not shared with any other wiring) which
are spaced at least 12 inches apart. This protects the
cable from physical damage while providing a degree
of electrical isolation. Also, do not run cable in close
proximity to other conductors which carry current to
heavy loads such as motors, motor starters, contac-
tors, or solenoids. Doing so could result in electrical
transients in the encoder cable which cause unde-
sired signal pulses.

Obviously not all receiving devices are the same.
However, connecting your encoder to one, no mat-
ter what type or brand it may be, is not difficult. As
discussed in the previous section, all encoders have
certain electrical features. Each of these features/
functions are identified in the encoder’s Electrical
Connections table along with its corresponding pin
and wire color. Each wire specified in the table must
be connected to the receiving device.
Determining where to connect each wire is as easy as
following the Electrical Connections table and match-
ing each wire to the proper terminal on the receiving
device. In general, no matter what type of receiving
device you are using, the terminal strip is marked,
indicating the proper location for each function/wire.
These markings may either be numbers or text labels
identifying functions. If they are numbers, the receiv-
ing device’s manual should define what function cor-
responds to each number.
Since receiving devices are made by various manu-
facturers, not all text labels/references are the same.
There are various ways to identify each function. Fol-
lowing are a few examples:

Note: Encoders that
feature differential
outputs will also have
complementary outputs
referenced as

Z-not).

When encoders have a differential line driver, there
are two signals for each of the outputs. Each signal (A,
B and Z) has a compliment or inverse (– A, – B and –Z
referred to as A not, B not, and Z not). The signal and
its compliment (i.e. A and –A) are separate outputs.
Connect each output to a separate input.
