The IP68-rated water proof through hole slip ring(optional IP65/66) is engineered for marine and agricultural applications. It features a 25mm ID within an 86mm OD housing, delivering 12 circuits at 10A each. What makes it special is the integrated 1000Base-T Ethernet transmission. So this slip ring can maintain gigabit speeds even in salt spray, fertilizer exposure, and continuous vibration.

Key Features
Sealed Housing
The internal components water proof through hole slip ring are enclosed in a protective housing. Silicone rings are used at the interface to seal against moisture and contaminants.
Waterproof Materials
Their housings are made of materials such as stainless steel or marine-grade aluminum, and are surface coated to retard corrosion.
Sealed Connectors and Cable Glands
They are equipped with waterproof connectors and cable entry points to maintain a seal.
Pressure Equalization
These slip rings use a pressure equalisation system, which allows them to be used in applications with high water pressure, such as deep-sea environments.
Applications
The water proof through hole slip rings are commonly used in these applications:
- Underwater robotics
- ROVs
- Marine sensors
- Outdoor surveillance
- Offshore wind turbines
- Wave energy converters
- Wastewater treatment
- Aquatic amusement rides
In essence, in conditions where water or humidity would typically cause short circuits or component failure in standard slip rings, they are used for uninterrupted electrical connection and data transmission.
