DEFINITION OF ELECTRICAL SLIP RINGS - ROTARY ELECTRICAL JOINT

The electrical slip ring, also known as rotary electrical joint, collector or electric swivel, is an essential device which facilitates the supply of power, the transmission of electrical signals from DC to High Frequency as well as microwave, Databus-signals, optical signals as well as media (compressed air, cooling fluids and other) from a rotating to a stationary plane. Obviously the quality of the slip ring is a key determinant in the quality of the overall system.

SCHLEIFRING is also renowned worldwide for its innovative technologies in the field of non-contacting high data rate signal transmission as well as non-contacting power transmission.

RESEARCH AND DEVELOPMENT

For years, SCHLEIFRING has undertaken intensive research and development efforts in order to cope with constantly and rapidly changing demands. SCHLEIFRING is the only supplier worldwide who offers a transmission system that is able to accurately handle the extreme data rates required for instance in the medical technology free of losses.

However, SCHLEIFRING offers more than only technology and innovative achievements. They take pride in their ability and commitment to solve problems and to provide customized solutions that help customers to meet demands, reduce costs and stay advanced.
 

THE WIDEST RANGE OF ELECTRICAL SLIP RING ASSEMBLIES

The transmission of power, signals and data between a rotating and a stationary plane is required in all areas of industrial design. Fixed connections via cables can only be applied for systems with a limited angle of rotation. For continuous rotation of 360 ° slip rings or rotary joints are required.

Besides contacting slip rings for the transfer of low data rates more and more non-contacting rotary joints are used, especially for the transmission of digital data at high bit rates. These systems are based on a worldwide patented capacitive non-contacting transmission technology which at present allows transmission of data rates from 100M Bits/s up to >5 GBits/s.

High Performance Slip rings for:

• All common BUS-Systems such as MIL-Bus, RS 422, Fast Ethernet, Gigabit Ethernet etc.

• Signal transmission of any kind, e.g. Thermo elements, Video, Encoder, Strain Gauge etc.

• Power transmission up to 15,000 A

Fiber Optic Rotary Joints

• Active and passive

• Single- and multi-channel

Media Rotary Joints

• For Hydraulic, Pneumatic, cooling and heating media, gas

• Up to 2000 l/min.

Non-Contacting Rotary Joints

• For Power and Signal Transmission

RF-Rotary Joints

• Microwave and Coaxial

• Digital/ analogue

• Up to 15 channels, DC - 40 GHz
