Description

The opto-electrical slip ring integrates a fiber optic rotary joint (FORJ) with electrical contact technology to enable simultaneous high-rate optical data transfer and power/signal transmission in a single rotating assembly.

Overview
  • Combines a FORJ (fiber optic rotary joint) with gold, silver or carbon electrical contacts to deliver both optical and electrical transmission in a single rotating assembly.
  • The FORJ provides high data rate optical transmission while contact technology transfers power and other electrical signals.


Design and capabilities
  • Single-channel FORJ can be integrated directly with slip ring mechanics.
  • FORJ mounting is engineered to withstand severe vibrations.
  • The rotating shaft provides a clear path for the fiber to pass through the assembly.
  • Customized outputs on both stator and rotor sides are available to match application requirements.
  • Hybrid solutions leverage brushes, contactless and optical transmission technologies within the same assembly.
  • Assemblies undergo rigorous qualification campaigns for harsh environments, covering vibration, temperature extremes, tightness (sealing) and aging.


Key applications
  • Wind turbines
  • Special machinery
  • Radars
  • Turrets
  • Remote weapons systems (including opto-electrical and video systems)


Technical specifications
  • Hybrid architecture: integrated FORJ + electrical contacts (gold, silver or carbon)
  • Optical: FORJ supports high data rates; single-channel FORJ integration possible
  • Electrical: contact technology for power and signal transfer; multiple contact materials available
  • Mechanical: FORJ mounting robust to severe vibration; shaft with clear fiber path
  • Customization: stator and rotor output configurations customizable
  • Qualification: designed and tested for harsh environments (vibration, extreme temperatures, sealing/tightness, aging)
  • Supported transmission technologies: brushes, contactless options and optical systems
