Kübler’s extensive range of encoders
have a broad application area, where
movement, position, speed or length
has to be measured or recognized.
The encoders are used in robotics,
medical technology, drive engineering,
in woodworking and packaging
industries, etc. The use of our preset
counters in combination with our
encoders is an easy and economic way
to build up many of the mentioned
applications.
Kübler has been certified according to
DIN EN ISO 9001 since 1995. The 4sign and other approbations, e.g. D
are indicators for the high quality of our

Introduction
you can count on
Encoders can be used in applications, where length, positions, speed or an
angular position should be measured. They transform mechanical movements
into electrical signals and can be divided into incremental and absolute measuring
systems.
Another basic distinguishing mark is solid-shaft or hollow-shaft encoder.
Nowadays hollow-shaft encoders are becoming more and more popular. Using a
hollow shaft encoder saves up 10-30% of costs and up to 50% of the required
space compared to a shaft encoder. This is achieved by not needing additional
couplings, brackets and other assembly aids. To mount a hollow shaft encoder, it
is simply necessary to put it on the shaft and a pin prevents the encoder from
rotating.
The basic advantage of hollow shaft encoders in comparison to shaft encoders is
shown in the diagram below (i.e. installation depth).
Example (Prices in DM):
• shaft encoder
• coupling
• bracket
• mounting time
300.30.50.10.390.-
• hollow shaft encoder
• simple pin
345.2.-
• mounting time
5.351.-
Result: Even the basic cost of the hollow shaft encoder is slightly higher
compared to the shaft encoder, the overall cost is about 10% less.

measure of speed, length or position. In absolute encoders, every position
corresponds to an unequivocal code pattern.

Conformity:
All Kübler encoders are fully comply with the 4 regulations and are intensively
tested in the EMC laboratories. They are conform to CE requirements according
to EN 50082-2, EN 50081-2 and EN 55011 class B.
High quality of signals:
All encoders from Kübler unlike other systems, are equipped with ageing and
temperature compensation.
Ageing compensation:
Each LED source will inevitably lose it’s power over a period of time. As a result,
the output signal degrades. The phase shift between channel A and B of 90°
becomes less and less. The direction of rotation can no longer be detected. A
special electronic circuit, which is built in the Kübler specific ASIC prevents this
effect.

90°
Channel B
Signals of an older encoder without ageing compensation
Channel A

Benefit: The ageing compensation circuit ensures the same signal, even after
many years of operating time. The down time of machines will be reduced
dramatically and the reliability is increased.
Temperature compensation:
This specialized circuit ensures that the quality of the signal will stay on the same
high level over the whole working temperature range.
Benefit: The positioning accuracy of a machine will not be affected by
temperature changes.
Short-circuit protection:
All Kübler encoders are equipped with short-circuit protection. This ensures, that if
there is a short-circuit or misconnection between the output channels the encoder
will not be destroyed. Once the encoder is connected the proper way, it will work
again.
Benefit: In cases of misconnection, which can happen quite easily (e.g. due to
unskilled workers), the encoder will not be destroyed.

Environmental conditions:
A significant impact on the lifetime of the encoder is made by the environment in
which the encoder is operating, e.g.:
• The ambient temperature
• The expected shaft load
• The possible grade of dust/dirt and humidity/liquids
Due to their design and the use of high quality components, our encoders are
suitable for applications in rough conditions.
Definition according to DIN standards 32 878
Working temperature:
Is defined as the environmental temperature, in which the encoder will produce
the signals defined in the data sheets.
Operating temperature:
Is defined as the environmental temperature which the encoder can withstand
without getting damaged.
Dirt/dust and humidity/water:
The IP classification according to EN 60529 describes how the encoder is
protected against particles and water. It is described as an abbreviation ”IP”
followed by two numbers.
The first digit defines the size of the particles. The higher the number the smaller
the particles.
The second digit defines the resistance against water. The higher the number, the
higher the water pressure can be.

Our encoders have a proctection up to IP 66.

protected against strong jets of water, e.g. for use on ship decks, limited

protection against the affects of immersion between 15 cm and 1 m
protected against long periods of immersion under pressure
Due to misalignment and other mechanical influences from outside, the shaft of
the encoder is exposed to a number of different loads. This has a direct impact on
the lifetime of the ball bearings and also on the electrical signal itself. If there is an
overload there will be an early wear and in the worst case it will lead to a failure of
the unit and to a destruction of the optical system inside.

Basic terms
On shaft encoders the maximal radial and axial load should not be exceeded. It is
highly recommended to use a coupling between the encoder shaft and the drive
shaft, see also the accessories and the mounting suggestions.
In the technical datasheets of the encoders, typical values for the radial and axial
load at the shaft end are listed. This is based on the lifetime of the ball bearing,
the speed, the mechanical load and the temperature.
For other loads the following diagrams can be used. All of the diagrams are based
on the following parameters:
• 60° C environmental temperature
• The axial load is always half the load compared to the radial load
Encoders from Kübler, such as the 9000 series can withstand up to 140 N radial
and 70 N axial load.

General
Assembly and function:
Kübler encoders operate on an electro-optical scanning principle.
A disk with a radial grating of lines and gaps rotates between a light source
(mostly a LED) and a receiver which produces a sinusoidal signal proportional to
the light received.

Processing of the signals:
Selecting an incremental
encoder:
Number of channels:
The sinusoidal signals are processed further in an electronic circuitry, usually a
Kübler specific ASIC. This is necessary because most controllers or counters (like
e.g. Kübler counters) require digital signals with a certain voltage level. Therefore
the signals are pre-processed in the encoder. The pre-processed signals are
transmitted by the output circuit depending on the application.
When selecting the right encoder, following parameters should be considered in
addition to the items mentioned on page 15-17.
Encoders with one output channel
Encoders with one output channel are used where no direction sensing is
needed, e.g. speed control or length measuring.
Encoders with two output channels
Applications, where the direction of a rotation should be sensed, e.g. positioning,
require encoders with two channels A and B being shifted 90° out of phase. By
detecting the phase shift, the direction can be located.
18
Incremental encoders

General
• Shaft turning clockwise, top-view of
shaft
• Inverted signals available
• 0-pulse is linked to AND with
channel A and B
Encoders with three output channels
In addition to the two channels A and B there is a zero signal available, that
appears once per turn. This can be used e.g. as a reference signal during the first
revolution after power up.
Multiplication of pulses:
The resolution of a two channel encoder can be multiplied by two or four using a
special edge detecting.
An encoder with physically 5000 pulses per revolution can generate 20000 pulses
per revolution using this technique.
Inverted signals:
When used in environments, with a lot of electrical noise and/or if very long cable
distances are required, we recommend to use encoders with inverted
(complementary) signals. These signals are always available with output circuits
of the RS 422 type and sinusoidal outputs. Kübler also offers them at push-pull
outputs.
Resolution:
The required angular or linear accuracy in an application will determine the
number of pulses per revolution. Linear movements first have to be transformed
into rotating movements by a measuring wheel or a spindle.
Example: An encoder is equipped with a measuring wheel. Every revolution
corresponds to a distance of 200 mm (circumference). The accuracy should be
0,1 mm. What is the required resolution (ppr)?
Given:
Circumference of the measuring wheel: C = 200 [mm]
Accuracy of the system: A 0,1 [mm]
Wanted: Resolution of the encoder: R ? [pulses/resolution]
Resolution = Circumference / Accuracy = C / A
The required resolution would be 2000 ppr (pulses per revolution).
Pulse frequency:
The required pulse frequency can be calculated. This is based on the number of
pulses per turn (ppr) and the speed (rpm). The max. pulse frequency is listed for
each encoder. Usually it is at 300 kHz. Kübler also offers high resolution encoders
with a pulse frequency of up to 800 kHz.
Example of how to calculate the required pulse frequency fmax:
Given: Speed n= 3000 min-1
Resolution of the encoder R = 1000 ppr
fmax = (n x R) / 60
The required pulse frequency is 50 kHz. Now you can compare this result with the
data of the encoder you would like to choose.

If the encoder is used in an environment with strong electrical noise and long
cables we highly recommend the use of inverted signals.
Sensor outputs:
The Sensor outputs are used if the distance from the encoder to the control unit is
very long and the voltage supply at the encoder could drop due to this long
distance.
The input impedance of the sensor inputs (Controller) is very high, and the
voltage drop on the sensor output line is almost zero. Due to this it is possible to
detect the actual supply voltage of the encoder (e.g. 4,2 V instead of 5 V). Based
on this information the controller will increase the voltage supply to e.g. 5,8 V.
Digital outputs:
The sinusoidal signal from the optical system is first digitised to have square wave
signals available.
• Shaft turning clockwise, top view of shaft
• Inverted signals are available
• 0-pulse is linked to AND with channel A and B
To transmit the signals there are two possible outputs available. RS 422 (TTL
compatible) or push pull (covers PNP or NPN). For choosing the suitable output
for the application the following points have to be considered:
• The corresponding unit / controller the encoder will be connected to
• The distance from the encoder to the receiver unit
• The sensitivity against electrical noise or other interferences
RS 422:
Normal PLC’s or IPC-controllers offer input cards according to RS 422
specifications. Here encoders with RS 422 should be chosen. Generally we
recommend to use RS 422 outputs for very long connecting lines, specially in an
area of increased electrical noise and interferences. Also for controllers with TTL
inputs the RS 422 should be used, however without the higher immunity against
electrical noise.

The sinusoidal signals are available as voltage signals or as current signals. They
can be further processed and can be multiplied by a factor of usually 10, 20, 50,
100, 400, 500, 1000 res. binary factors (512, 1024). Due to the interpolation of the
two signals, which are 90° out of phase, a very high resolution can be achieved.
This makes these kind of signals specially useful for applications in which very
high resolutions are required. Further they are very suitable for digital drives with
a very slow and precise movement, e.g. for grinding machines or lifts and
elevators.

• Always use shielded cables
• The core diameter of the signal cores should be ≥ 0,14 mm2
• The core diameter of the voltage supply cores should be large enough depending on the cable length, that the voltage
supply of the encoder is high enough and the signals do not go below the minimum levels!
We strictly recommend the use of the cable types written down in the accessories.

Measuring wheels
Description and applications:
Measuring wheels are utilized in
combination with pulse generators to
measure the lengths of moving
measured material in the wood-,
paper, metal, textile and plastic
industry.
Measuring wheels c = 0.2 m
No. (261), 291, 241, (234), 211 (start

Measuring wheels c = 0.5 m
No. 512, 542, 552, 562, 592 (start left)
When selecting a measuring wheel,
the first consideration is the type of
material to be measured as this serves
as the basis for determining the
surface finish or coating of the
measuring wheel.
Numbers in brackets indicate that the measuring wheel is
not available anymore.

Please note:
If a measuring wheel is mounted directly on the shaft of a rotary encoder, the pressure force between the measuring wheel
and measured material should not exceed the radial shaft load listed on the data sheet of the encoder. In addition, the
measuring wheels can only be used for in-house purposes which are not subject to the stipulations of the German calibration
code.

Mounting advices for hollow shaft
encoders:
Hollow shaft encoders can be mounted
very fast and easily.
• Put it onto the drive shaft
• Fasten the integrated clamping
device
• Prevent torque movements
The easiest way of torque movement
prevention is the use of a simple pin
according to DIN 7-Ø 4 mm.

Mounting examples:
Mounting of a hollow shaft encoder
with torque stop and pin.
(easiest and fastest mounting)
Standard hollow shaft encoders are
equipped with the torque stop.
Application:
If axial play is less than 0.5 mm. Resolution up to 2500 ppr (If no pulse
doubling is used)
Other mounting possibilities:
• With the mounting kit for hollow shaft
encoders many mounting variations
can be realized.
• Flexible mounting sheet metal. Small
tolerances of the drive’s shaft can be
compensated although torque
movements of the encoder are
prevented.
• Stator coupling. This is the best
solution, if resolutions > 2000 ppr
have to be realized. Failures in
accuracy caused by torque movements of the encoder are prevented
and radial, axial and angular plays
are balanced.
Mounting of a hollow shaft encoder
with extended torque stop and long
pin.
Application:
Specially recommended, if there is a
large axial play.
Due to the bigger mounting radius of
the pin, the resolution can be higher
(up to 3600 ppr, if no pulse doubling is
used)
Mounting of a hollow shaft encoder
with the stator coupling
Application:
For higher resolution or if no pin can
be used, due to mechanical
restrictions.
No restriction to resolution

Couplings
Description and application:
Manufacturing and installation
tolerances as well as the effects of
temperature cause alignment errors
between shafts in drive engineering
which can sometimes lead to extreme
overload on the bearings.
This may result in increased wear of
the bearings and may lead to
premature failure of the encoder. By
using couplings these alignment errors
can be compensated, thereby reducing
the load on the bearings to a minimum.
A distinction should be made between
three different kinds of alignment error:
radial, angular and axial displacement.
Whilst with torsion-free but bendable
shaft couplings, axial shaft
displacements produce only static
forces in the coupling, radial and angular displacements produce alternating
stresses, restoring forces and
moments which may have an impact
on adjoining components (shaft
bearings). Depending on the type of
coupling, particular attention should be
paid to radial shaft displacement which
should be kept to a minimum.
Installation instructions:
1. Check shaft for displacement; See
technical data for details
2. Align and adjust coupling on
shafts.
3. Tighten locking screws carefully.
Avoid overtightening.
4. During installation protect the
coupling from damage and from
overbending.
Areas of application:
Metal bellows-type couplings (.1101
and .1201) are recommended as an
inexpensive type of coupling. They are
also suitable for compensating larger
angle displacements.
Spring washer-type couplings (.1300
and .1400) are used mainly in those
cases where high speeds and smaller
angle displacements are involved. For
applications where electrical insulation
between rotary encoder and drive is
required, the electrically insulating
spring whasher-type coupling should
be employed.
Cardanic couplings (.1500) are
particularly suitable for extreme
operating conditions. We recommend
these couplings in combination with
our 9000/9010 series of encoders.
