SLIP RING
AUROTAC®
AUROTAC® is a rotating slip ring designed and manufactured by Elet.Ca. Mechanical and electrical solutions
employed for such product come out directly from the
know-how of Elet.Ca acquired during its many-year experience on similar products addressed to the military sector. Thanks to a thorough research work and experiences
performed on materials and treatments that Elet.Ca continues and will continue to carry out, an optimal configuration of this product has been found, giving excellent
guarantees of reliability for all considered parameters.
Thanks to its different types of interface, the AUROTAC®
slip ring is suitable for several applications.
TECHNOLOGY
The AUROTAC® slip ring is totally manufactured in aluminium, with IP 65 protection in order to withstand heavy environmental conditions as temperature, vibrations,
socks and (or) aggressive atmospheric agents.
Their Tefzel cables guarantee utilization at temperature
ranges of –30° ÷ +85°, high insulation rate, low induction
between the cable due to excellent dielectric strength.
The mobile part and fixed part of the slip ring are joined
through a strong shaft bearing the rings fixed to the case
by means of suitable ball bearings, assuring a soft and
flowing movement.
The core of the slip ring, consisting of the brush-ring
matching, allows today to operate within the best parameters concerning total resistance of the circuit, dynamic
resistance of contact (noise) and cross-talk. The above
characteristics kept also at operation speeds exceeding
500 Rpm (1000 Rpm max) are guaranteed by employing
pure copper as well as gold against gold matching.
APPLICATIONS
The range of utilization of standard AUROTAC® having
the characteristics described hereunder includes the
transfer of continue or modulated signals from and to
different peripherals, instrumentation, coils, thermocouples, robotics, turntables, data Bus, television cameras,
etc... within limits of standard configuration.
OPTIONALS
To fulfill special or standard requirements or to improve
the pass-band of the slip ring, it can be equipped with cables and special fittings, electric shielding and everything
needed for special uses (customers requirements).
UTILIZATION FOR DIGITAL SYSTEMS
Physical limits of operation frequency impedance and
data-rate of standard cables can be widely over come
by using twisted cables fulfilling standards of cables in
conformity with 5, 5e, 6 categories and in accordance
with IEEE 802.3 standards for employments in Giga-Bit
- Ethernet.

SERVICE AND INSTRUCTIONS MOUNTING
MAINTENANCE
Assure good mechanical locking of the slip ring as well as
correct earthing of it as described on paragraph “examples of mounting”.
During installation check that the mechanical “play”
between fixed part and mobile part of the slip ring is lower than ±0,2 mm in order to minimize as much as possible mechanical stress due to induced vibrations causing
shortening of average life of the slip ring. The cable must
be strip with suitable tools and/or with sharp blades in
order not to ruin the underlying strands or in the shielded
cables. Avoid stresses or tensions between the slip ring
body and the cable outputs. Ensure correct connections
on sockets. Damaged cables may cause slip ring operation failures.
As the electrical coupling is dry (it means that lubricant
oils are not needed), maintenance is not required.
• The AUROTAC® slip ring unit can be used both horizontally and vertically.
• Provide current protection (fuse) on wires attached to slip
ring. Over-current conditions can cause failure of slip ring.
CAUTION:
The aluminum body may be electrically “hot” after failure.
Disable power source before handling a suspected failed
slip ring.
MEAN-LIFE
Data concerning mean-life obtained after indoor laboratory tests must be considered indicatively, unless some
tests conditions are reproduced. Mean-life of each system depends on the combination of many variables as:
• type of movement (alternating and (or) continuous);
• number of working hours per day;
• presence of mechanical vibrations;
• backlash between fixed parts and mobile parts;
• work environment;
• operation temperature and (or) changes of temperature
• final application.
Our staff of technicians is at your disposal for any further
information and any special requirement.
WARRANTY: Units are guaranteed for one year from date of purchase against
defective materials and workmanship. Replacement will be made except for defects caused by abnormal use or mishandling. All statements and technical information contained herein, or presented by the manufacturer or his representative are rendered in good faith. User must assume responsibility to determine
suitability of the product for intended use. The manufacturer shall not be liable
