*Maximum total current is dependent on duty cycle, ambient temperature and specific configuration. Consult factory to ensure configuration is suitable for application.

176 winch slip ring 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 Model 176 is comprised of electrical power and signal passes, and provides superior performance and reliability in demanding operational environments. Highly configurable, it is customized to meet customer specific needs. 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
