140mm and 168mm Winch Slip Rings for Offshore Applications
Built for Power, Precision, and Harsh Marine Conditions
Penlink’s 140mm and 168mm winch slip rings are advanced electro-optical solutions purpose-built for heavy-duty offshore operations where high voltage, high current, and modular adaptability are mission-critical. These large-format slip rings are designed to thrive in the most demanding marine environments—handling saltwater exposure, intense vibration, mechanical shock, and extreme temperature variations with ease.
With proven performance in ROV launch and recovery systems, LARS & TMS platforms, seismic survey winches, and deck machinery, these slip rings offer unmatched reliability and customization. Whether your application requires up to 5000V, 80A, or 56 signal channels, Penlink’s modular architecture allows for tailored configurations that meet the specific electrical, data, and fiber-optic needs of your system.
These slip rings are fully compatible with:
- Industrial protocols: Ethernet, Profibus, RS485, COAX
- Fiber connectors: ST, FC, SC, LC
- Optical transmission: Single-mode and multi-mode, up to 24 channels
- Environmental protection: IP66 sealing, with options integrated heaters, and air purge systems
Whether installed topside or subsea, Penlink’s 140mm and 168mm slip rings are trusted by engineers in offshore energy, marine robotics, and oceanographic research for their durability, signal integrity, and long service life.
