Thank you for your interest in Trolex Slip Ring Units.
Slip Ring Units have been a major part of the company product portfolio
since trading began in 1972. Each type has been designed and manufactured
with maximum consideration for the application - many being for the mining,
offshore and petrochemical industries where Explosion Protected equipment
is necessary. (See also Design page). |

TRANSMISSION OF SIGNALS THROUGH SLIP RINGS |
|
| |
A Trolex Slip Ring Unit is as reliable as any other electrical control
or monitoring device using well established and proven designs.
The transmission of signals is not a problem, if circuit characteristics
are known we are pleased to consider the details and where possible provide
information relating to similar applications.
The slip ring circuits are of the sliding contact design with a minimum
of two-brush contacts/slip ring. Precious metals are used to improve data
transmission of signal circuits. |
|
| |
|
|
| |
|
|
| |
TYPES OF SIGNALS |
|
| |
Listed below are samples of the type of signals, digital or analogue
that have successfully been transmitted across the rotating interface
of our Slip Ring Units.
- Video
- Communications
- Serial Links RS232/RS485
- Superimposed signals onto 1kV power circuits
- Data - PLC 115.2 kBaud (2 x 1,000,000 transmitted and received messages
without an error)
- ESD signals
- Fire & Gas
- Fibre optic*: single or multi-mode and 1mm plastics fibre
|
|
| |
|
|
| |
* For pressure compensated and multi-pass Fibre Optic Rotary Joints, we are able to pass on the benefits of our suppliers' warranties (please consult our Terms and Conditions of Sale for more information) |

TESTING |
|
| |
All units are tested prior to despatch, this includes but is not limited
to, continuity, insulation resistance, dielectric strength, torque and
rotational tests.
Electrically the circuits are capable of moderate fault levels and surges
without detriment. The slip rings, brush gear and terminal designs are
well proven. |
|
| |
|
|
| |
|
|
| |
DESPATCH |
|
| |
A comprehensive Maintenance and Instruction Manual is supplied with each
unit and includes a Trolex Certificate of Conformity and Declaration of
Incorporation. All Trolex Engineering products are carefully packaged
for protection during transport. |
