What are Slip Rings?

A Slip Ring Unit is an electromechanical device which allows the transmission of power and electrical signals from a stationary to a rotating structure.  Slip Rings can be used in any electromechanical system which requires unrestrained, intermittent or continuous rotation while transmitting power and/or data.  It can improve mechanical performance, simplify system operation and eliminate damage-prone wires fixed/hanging from moveable joints.

As leading slip ring manufacturers, Trolex Engineering can offer proven slip ring technology, both ATEX certified and IECEx certified.

How do Slip Rings work?

The Slip Rings function is to make one or more continuous electrical connections from points in a stationary unit to points in a rotating section.

You may have heard them called a number of names - rotary electrical interface, collector, swivel, and rotary joint - however, they are all the same product, and throughout our website, will be referred to as Slip Rings.  They are sometimes referred to as commutator, however commutators are specialised for use on DC motors and generators.  While commutators are segmented, slip rings are continuous.

Slip Ring Maintenance

Regular and appropriate maintenance is paramount for the safety and service life of the slip ring.  Full details will be provided in the Maintenance Manual provided with the product itself.

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/or Declaration of Incorporation. All Trolex Engineering products are carefully packaged for protection during transport.
