Model 176 with FORJ
5.52" DIAMETER ELECTRICAL SLIP RING WITH FIBER OPTIC ROTARY JOINT

The Model 176 with FORJ combination has served the marine industry for over 30 years and is ideal for applications where voltages exceed the 1000 V / 7 A capabilities of our Model 180.
The ESR portion is comprised of electrical power and signal passes. Highly configurable, it is customized to meet customer specific needs, providing superior performance and reliability in demanding operating environments. For the hazardous area environment, there is an option for a fully certified, flameproof enclosure. When underwater operational capability is required, it can also be adapted for use as a fluid-filled, pressure compensated unit.
Features
- Electrical passes rated to 7200 V / 20 A
- Up to 52 fiber optic channels in a very small form factor
- Pigtail exits are capable of being sealed to IP66 standards
- Sealed housing design tested to IP66 standards
- Can accommodate a variety of wire and cable types
- Hazardous area certification available
- Stainless steel construction
- Rugged design intended for harsh environments
- Reliable operation under shock and vibration
- Combined with Fluid Rotary Unions (FRU), see Model 173
Benefits
- Compliance with the highest quality standards for design, manufacture and test
- Maintenance free operation
- More than 30 years of proven field performance
- Integration with Fiber Optic Rotary Joint (FORJ) and Fluid Rotary Unions (FRU) to provide a complete rotating interface solution
