Hi-Frequency Slip Ring

A slip ring is also called a rotary electrical interface, collector, swivel or rotary joint. A slip ring can be used in any electromechanical system that requires unrestrained, continuous rotation while transmitting power and / or data from a stationary to a rotating structure. A slip ring can improve system performance by simplifying operations and eliminating damage-prone wires dangling from moving joints.

The LPHF Series features precious metal contacts at the rotary interface. Flying lead wires on the rotating side and solder terminals on the stator side complete the electrical connections. Precision ball bearings and the patented fiber brush design allow operation up to 10, 000 rpm without the need for cooling equipment. Fiber brush technology offers several advantages over conventional slip ring contacts including multiple points of contact per brush bundle, low contact force per fiber and low contact wear rates. In addition, fiber brushes do not require lubrication and produce virtually no wear
It is specially designed for high frequency signal transmission, the frequency could be high to 50GHz
