Coaxial Rotary Joint High Performance Slip Ring for Car Mobile Communications

Coaxial Rotary Joint High Performance Slip Ring for Car Mobile Communications​

Rotary High Performance Slip Ring ​Description

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
