Contactless Transmission Capacitive Data Link GigaCAP®

Transmission Technologies

The application of industrial standard protocols is in high demand. Communication standards such as Gigabit Ethernet or Fibre Channel are supported and allow for data rates up to 10 Gbit/s. Thus, the system integration of the data channels is simplified as compo-nents from the IT marketplace can be used. The modular design allows the system to be quickly and easily adapt-ed to customer-specific applications.

Classic applications • Automation, industrial scanners• Customer-specific applications• Radar, periscopes

Features:• Multiple stackable channels• Unidirectional or bidirectional• Max. diameter: 2,000 mm• Height: 25 mm/1" per stack plus housing• Shapes: two circuit boards for 2 channels in a metal housing• Rotational speed: only limited by mechanical restrictions

Wear-resistant, high noise immunity combined with excellent EMC qualities, high reliability and bit error rates of < 10-12.

Contactless Transmission Inductive Power


Classic applications• Cleanroom applications • Vacuum technology• Semiconductor industry • Printing machines• Balancing machines • Pick and place machines• Packaging lines • Plastic processing machines• Bottling machines

In addition to contacting slip rings, contactless rotary joints are becom-ing more and more popular.

SCHLEIFRING’s worldwide-patented technology for inductive, contactless power transmission allows voltages of 24 V up to 400 V within a range of 1 W to 10 KW.Especially in applications with high rotational speeds, our contactless slip rings ensure a long, wear-free service life, which cannot be achieved with a contacting transmission system.

This new compact hybrid unit combines contactless power and signal trans-mission, allowing temperature monitoring of rollers in foil processing machines for instance.Contactless power and signal transmission provides a wide range of options for industrial innovations.

6

The slip ring is an essential device for the supply of power and the transmis-sion of electrical signals. The quality of the slip ring is therefore a key factor for the quality of the overall system. Due to the constantly increasing vol-ume of transmitted data nowadays, contacting slip ring systems use pre-cious metal sliding technology to counter the physical limitations.

Sensitive data and digital signals e.g. piezoelectric or strain gauge signals

SCHLEIFRING’s gold wire technology and the contact configuration of silver-graphite brushes on brass rings allow for excellent signal and data transmission: • Extremely low electrical noise and contact resistance • Long, low-maintenance service life • High contact reliability • Crosstalk isolation• Reliable operation under shock, vibration and extreme temperatures• Transmission of all common bus systems

Contacting Transmission Signal & Data Transmission

Our slip rings provide the dynamic electrical connection between static and rotating mechanical elements. They operate as rotary interfaces con-tinually transferring electrical power in any direction.

Slip rings are produced in various types and sizes depending on:

• Electrical requirements • Mechanical property requirements • Operating environment• Customer needs

From low to high power

SCHLEIFRING’s silver braid brushes or silver-graphite brushes on silver rings as well as the gold wire technology provide for optimum power transmission. Depending on the technical requirements, they allow excellent transmission of low power up to and above 1,000 A at high rotational speeds and with a long service life.

Slip ring systems combining a multitude of transmission tech-nologies

Our products’ range of applications covers standard designs for simple tasks up to highly complex customer-specific systems often involving sev-eral hundred rings.Hybrid slip ring units combine various transmission technologies to transmit electrical power, signals, bus data, RF signals and media in one system. Because of the great variety of de-mands made upon the slip ring as-sembly, it is imperative that the sys-tem designers give thought to the space available and performance ex-pected early in the design stage.

The product shown contains:

• Power up to 15,000 V/ 700 A carbon/silver technology • Signal and data (bus, video): gold/gold technology • Radio frequency DC rotary joints up to 94 GHz • Encoder • Fiber-optic rotary joint• Contactless data link up to 10 Gbit/s: GigaCAP® • Media rotary joints for hydraulic, pneumatic, cooling/heating media, gas up to 2,000 L/min

Requirements for industrial applica-tions with regard to service life and data transmission rates (e.g. Fast / GigaBit Ethernet, Profinet) are higher than ever before.

For this reason SCHLEIFRING offers the ideal solution: contactless power and data transmission. Without the general use of brushes running on metallic surfaces this sys-tem is almost maintenance-free at continuously high rotational speeds.

Functionality:

The power is transmitted inductively from the stator to the rotor by a ro-tationally symmetric transformer. The resulting efficiency is over 95 %, meaning that the heat development is less than 5 %. Currently, slip ring systems from 1 W to 10 kW are used for industrial appli-cations; for medical applications, sys-tems up to 200 kW are used. Data transmission occurs capacitively in the near field.

Advantages: external interference fields have no influence on bit error rates < 10-12 at data rates of up to 10 Gbit/s per channel (in parallel circuits > 40 Gbit/s).

Slip Ring Units Turntables


A standard of highest flexibility

Due to their modular design, the stan-dard G200, G300 and G400 series slip rings offer highest flexibility for the transmission of electrical power, signals, bus system data and video signals for many demanding rotating applications. An additional optional range of opti-cal and RF rotary joints as well as me-dia rotary joints for air, water and oil rounds off this series.

Modular design

Three basic units and 15 different modules allow for millions of combi-nations. The modules can be selected out of a table and used in any com-bination to meet your requirements. One slip ring system allows the trans-mission of up to 126 pathways. The housing length of the slip ring system is defined by the number and type of modules stacked. The free inner bores of these series allows optical and RF rotary joints as well as a range of me-dia rotary joints to be combined..

Systems for the pharmaceutical and food processing industries

Designed especially for industrial con-trol equipment in the pharmaceutical, chemical and food processing indus-tries, SCHLEIFRING offers self-con-tained capsule slip ring solutions with stainless steel housings. All versions are resistant to water and dust ingress (industrial protection class IP65 ac-cording to EN 60529) and designed to operate at temperatures up to +70 °C.

The gold wire technology guarantees excellent results with regard to the transmission of power, data and com-mon bus signals such as Profibus and Fast Ethernet. The electrical slip ring is optionally available with a media ro-tary joint.

The requirements on the slip ring sys-tems are as varied as the applications in the pharmaceutical and food pro-cessing industries themselves.

SCHLEIFRING’s silver braid brush contact configuration guarantees the best signal transmission results even at high rotational speeds.
