Contacting Technology
AOOD classic contacting technology is made by contacting of a special bunch of brush wires and a conductive band or circle mounted on a shaft. It has superior power, signal and data transferring capability, especially gold on gold contacting can deal with weak signal or high speed data transmission and maintain high reliability. Silver on silver contacting can meet the need of lower cost purpose of reliable power transmission.
Contactless Technology
In CT scanner, it needs a slip ring with big through bore to ensure the transfer of high data rates under high speed working. AOOD engineers develop non-contacting transmission technology for these applications. Non-contacting slip rings offer superior high speed power or data transfer with no maintenance and longer service life than common brushes contacting slip rings.
Rolling-rings Contact Technology
AOOD new rolling-rings technology adopts rolling-rings contacting to realize the transfer performance of a slip ring, which use rings of spring copper plated with gold which located between two precious metal grooves instead of traditional sliding contact. It has lower contacting resistance, lower wear, lower electronic noise, longer lifetime and higher current transfer capacity. It is the perfect slip ring solution for those systems need large size, high current capacity and long lifetime slip rings. AOOD rolling-ring contacting slip rings are performing their excellent function in medical, defense, aerospace and navigation applications.
Liquid Mercury
AOOD mercury slip rings use a pool of liquid mercury molecularly bonded to the contacts instead of traditional sliding brush contact. Their distinctive contact principle ensure they can keep low resistance and very stable connection under super high working speed, and are capable to transfer up to 10000A current per pole. Most AOOD high current mercury slip rings are used in welding machines.
Fiber Optic
Fiber optic transmission was born for highest data rates. AOOD fiber optic technology can ensure up to 10 Gbit/s data rates even under extreme environments. AOOD fiber optic rotary joints are built with stainless steel body and up to IP68 protection, can be used in almost any type of applications from medical equipment, ROVs to military surveillance radars. Fiber optic transmission can be integrated with electrical sliding contacting slip rings to meet the need of electro-optic hybrid slip rings systems.
High Frequency
AOOD offer high frequency transmission solution between a fixed platform and a rotary platform, such as TV cameras, unmanned aerial vehicles and radar systems. AOOD allow signal transmission in the frequency range from DC up to 20GHz, the HF rotary joint can be integrated into the electrical slip ring as needed.
Media Rotary Union
AOOD offer media transmission solutions by transferring fluids or gases from a fixed source to a rotating source while allowing moving. Media rotary unions are utilized in a variety of applications from the rotary dial indexing tables to sheet metal processing mandrels to hydraulic forestry equipment. A slip ring, a fiber optic rotary joint, a HF rotary joint and an encoder can be integrated into a rotary union system. Whether you require specific solutions for high pressure, high working speed or high flow volumes, just challenge AOOD.
