While only one Roll-Ring is installed in each groove, more grooves and more rolling rings can be added per channel to increase current handling capacity. Channels can be added to meet application requirements.
The pictured layout is said to minimize high-frequency coupling and let the device pass data at rates to 15 Mbit/s at frequencies to 30 MHz. Various insulations are available to increase voltage handling capability up to 4,000V. The developer says the unit accommodates most manufacturing tolerance variations making it possible to stack up to 70 channels and more while maintaining life and electrical performance. The interface does not require lubrication and thus is suitable for vacuum applications.
The devices have survived three-axis 180 G shock loads and have operated for over 240 million revolutions. In an aircraft gyroscope, the device allowed a 99% reduction in torque over slip rings.
The developer says its Roll-Rings can replace slip rings in a many applications but not all because they sometimes require more space than that available. As you might expect, the units are more expensive than slip rings of similar capacity. WPE
