3-Channel RF Rotary Joint with 60RPM Rotating Speed & Frequency Up To 3 GHz for Remotely Operated Vehicles
Description
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 part to a rotating part. A slip ring can improve system performance by simplifying operations and eliminating damage-prone wires wrapping from moving joints.
The LPHF Series features precious metal contacts at the rotary interface. 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, with frequency up to 50GHz.
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 cooling equipment.
