Intercom connections from inside of a vehicle to an external turret require a connective cable for power and communications. This cable connection prevents the turret from having a 360 degrees of motion. Additionally, powered turrets require external batteries, which must be stored in or on the turret itself. Traditional slip rings are not designed for a large center opening, and using them would require redesign and replacement of turret bearings.

Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed and patented a Rotary Electrical Contact that allows the passing of communications signals, vehicle power, and other cable signals to a vehicle turret without the need for cords or other hazards. This innovative design is applicable for all applications where large slip rings are employed or where 360 degrees of motion is required but without cord or cable connections.

-Can be used to upgrade existing slip ring capacity
-Simple and inexpensive retrofit
-Provides continuous communication while allowing 360 degree rotation

Potential Applications:
-Law Enforcement
-Any application where slip rings are used.
-Provides a simple and inexpensive retrofit of existing slip rings
