How a Slip Ring Works
A
Connections Between
Source Harness & Ring
Leads
slip ring is a
continuity device which
transfers electrical current
through a continuous
rotation from a stationary
member to a rotating
member.
There are two distinct
parts of a slip ring. One
part is the conductor ring
“core” stack and mounting
tube or shaft. The other
part is the brushes,
mounting base and
housing.

1.50" Bore
The Standard Bearer for All UEA Slip Rings
The UEA 1.50" bore slip ring is the original one our
competitors have tried unsuccessfully to copy. This
slip ring is the standard by which other designs are
judged in the industrial, heavy equipment and
machinery industries.
The 1.50" bore UEA Slip Ring has proven its worth. It will
work in harsh conditions and environments where other,
lesser quality slip rings fail. However, in addition to the
ability to handle rugged uses, the UEA 1.50" bore slip ring
has proven its superior performance in today’s high-tech
world of audio, video, data and electronic signals through
continuous rotation.
When your design parameters work around a 1.50" bore
UEA Slip Ring, you have entered a world of unlimited
variables and options to meet your requirements.

Electronic Condition Circuitry
Brush Test
Brush Test UEA has done testing to compare various
brush and ring material combinations to determine
the operating characteristics and advantages or disadvantages of each. The brush materials included
silver graphite and UEA standard copper graphite.
The ring materials were #330 brass or coin silver.
Also tested were brushes radiused to provide 2
small contact points per brush (4 points per brush
pair).
The test data showed that the noise generated in a
slip ring assembly will vary in direct proportion to
the level of current through the brush to ring interface. As current is increased, the voltage drop is
increased by the same proportion due to the fixed
circuit resistance. The variation also increases by
this same proportion, indicating the variation in
resistance of the brush to ring interface.
There was very little difference in performance of
the various circuits at low current levels, but as the
current was increased, the variations became large
enough to be a factor in material selection. An
interesting finding was that the brush material had
a much greater influence on the performance of the
circuit than the ring material.
In addition to signal performance, environmental
factors must be taken into consideration for selection of material. For example, in a hostile environment, a higher grade material may be needed to
reduce surface degradation. This testing indicated
the advantages of matching materials and brush
shape to meet specific operating conditions.
Ring Performance Test
To evaluate ring performance with regard to possible applications in the instrument class slip ring
market, a 15 amp circuit, 1.50" (38.1mm) bore ring
was selected. Tests were designed to bring out
operational parameters for determining applications. The test data indicated that slip rings used on
instrumentation applications produced highly satisfactory results.

Ring Performance Test
To evaluate ring performance with regard to possible applications in the instrument class slip ring
market, a 15 amp circuit, 1.50" (38.1mm) bore ring
was selected. Tests were designed to bring out
operational parameters for determining applications. The test data indicated that slip rings used on
instrumentation applications produced highly satisfactory results.
Graph A. Brush-to-ring dynamic contact resistance as
the ring turns the first 10,000 times and typical dynamic contact resistance for standard 0.1875" (4.8mm)
wide ring and 15 amp brush pair.
Graph B. Electrical noise in millivolts caused by the
brushes sliding on ring during operation, using a 2 amp
load condition and 90 RPM rotational speed. Test results
support many possible applications in low-level signal
transfer.
Graph C. Level of signal present in decibels when two
rings carrying signals are separated by a common ground
ring. The isolation provided is ideal for serial data transfer
and similar applications.

Position Sensors
Knowing Your Rotary Position
UEA Slip Rings are always in the center of a 360° rotation.
Various rotary applications are improved by the ability to
sense a single position, multiple positions, or to define one
or more areas. This sensing of position allows customer
defined functions to operate within the requirements of
each individualized application.
UEA offers two position sensing systems which both
provide a high degree of accuracy. The Cam & Switch
Design is our most popular system offering accurate
performance for up to 3 defined areas. Potentiometers
are designed for use in applications requiring variable
position indication.
Both position sensing systems were conceptualized for the
UEA 1.5" bore ring model, but either system can be adapted
to our larger bore models. The Cam & Switch Design and
the Continuous Through-bore Potentiometer are installed
near the slip ring base casting and bearing, eliminating
inaccuracies caused by brush and core stud flexing. This
also leaves the center bore open through the slip ring
assembly for air lines, linkage, etc. The 2.00" O.D.
Potentiometer is mounted above the center lead
connections at the top of the assembly. This allows
easier replacement of the potentiometer if necessary.
Cam & Switch Design Features
• Factory set accuracies of +– 0.5°

Special Rings
Meeting the Needs for Unique Applications
Special applications often call for special slip rings.
By combining standard, off-the-shelf components
into custom slip rings, UEA designs meet the design
parameters and environmental conditions of the
application. Here are some examples of special slip
rings which were designed to be application specific.
118 Conductor Slip Ring — One of our largest
Recent Special Ring requests which were built by UEA
include:
• High Conductor Count rings were built to handle
multiple functions
• Bore Sizes – built in conjunction with high
conductor counts, these rings have bore sizes to
accommodate special wiring, water hoses and
hydraulic or pneumatic connections
• Unusual Environments –UEA has built special
rings to be used in salt mines, outer space, frigid
Alaskan climates and extreme desert heat
• Position Sensing – although this capability is
usually provided only on smaller bore rings, UEA
has the capability to offer position sensing on most
slip ring models
Potentiometer position sensing at top of slip ring
Electro–pneumatic swivel assembly with
circuit combinations from high power to
control. Includes potentiometer position
sensor at base of slip ring

How To Order Slip Rings
The More We Know About Your Application, the
Better We Can Customize Your Slip Ring
UEA Slip Rings have to work in applications with widely different types of electrical loads and data signals, as
well as in a variety of environmental and operating
conditions. Working closely with the OEM or end user,
we get as much insight as possible into each application in order to evaluate the needs and potential problems that might arise in that particular situation. Please
describe the conditions of operation as accurately and
completely as possible so that we can supply you with
a product that will perform well and meet your highest
expectations.
We look at the combination of factors in order to recommend a UEA Slip Ring for every application. For
example, if a slip ring assembly is carrying low level
data signals, is rotating almost constantly (high duty
cycle) and is used indoors, standard materials will perform well. On the other hand, with the same signal in
an outdoor application or in an environment with wide
variations in temperature and humidity, in combination with infrequent rotation, special materials may be
needed to maintain signal integrity.
In some manufacturing or processing facilities, corrosive gases may be present in the air around the slip
ring. If the application requires a high duty cycle, surface oxidation will be kept scrubbed off by the
mechanical action of the brushes. However, if the slip
ring is not being rotated through complete rotations
or is infrequently rotated, special materials would be
needed to prevent surface oxidation that could impair
the function of the slip ring.
