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.
