Rotary Data Transmission
Real Time and High speed Data Rate is our expertise!
Data transmission is the transfer of data from one device to another, over a communication channel. For Stationary Data Transmission the channel is simply a copper cable terminated with specific connectors, used to wire the devices involved in the Data Transfer. For Rotary Data Transmission, it is necessary to add a Data Slip Ring that keeps the rotary and static parts of the machine in communication. Data Transmission is performed using a common set of rules so that the sender and the receiver can understand each other (similar to a common spoken language) called a Data Protocol. Each Data Protocol implies the use of a defined cable, with specific characteristics and electrical parameters. The gold rule for a perfect Rotary Data Transmission is to not modify the characteristics of the cable adding the Data Slip Ring. This is of course not possible, since we will have a different geometry of the Data Slip Ring in respect to a cable, different materials, different composition of poles... our expertise and know-how alleviates worsening on Data Transmission, choosing the best solutions to properly manage all the electrical parameters, like characteristic impedance, crosstalk and attenuation. Particular attention must be paid to the materials for data transfer and insulation, among different wires or pairs, shielding, interconnections.

Frequently asked questions
Which kind of Data can be transmitted with a Data Slip Ring?
Conductix-Wampfler is able to provide reliable solutions for transmitting any kind of data, going from low Data Rate serial transmissions up to the most demanding Real Time Industrial Ethernet at 1 Gbps. This includes encoder, audio, video... basically every type of data that your rotating machine could need.
What is Data Transmission speed?
Data Transmission speed or Data Rate is the number of bits that are transmitted in a unit of time. This is generally measured in bits per second and so depending on the Data Rate we generally speak about kilobits (thousand bits - kbps), megabits (million bits - Mbps) or gigabits (billion bits - Gbps).
Which is the difference between Bandwidth and Data Rate?
Bandwidth is a measure of the transmission capacity of a network over a specific period of time. It is the rate at which a link may send or receive bits per second and it is measured in hertz (Hz). Data rate is used to measure how fast data is transferred from one point to another. It refers to the actual amount of data transferred and it is measured in bits per second (bps).
Data Rate and Bandwidth are related but they are not the same.
What do we mean with "fieldbus"?
Fieldbus is a means of communication among several input and output devices, such as sensors, switches, valves, drives, etc. without the need to connect each individual device back to the controller (PLC, Industrial PC etc.). Before the introduction of fieldbus systems computers would connect using direct serial connections whereby only two devices could communicate per connection. The Fieldbus, allows hundreds of analogue and digital points to connect simultaneously. This reduces both the number of cables required, whilst also cutting down the length of cable needed. Examples of Fieldbus are Canopen, Canbus, Profibus, and all Industrial Ethernet like Ethercat, Ethernet/IP, Sercos III, PowerLink...
What does Cat.5, Cat.5e, Cat.6, Cat.7...mean?
The "Cat" is a short form for "Category" and it is a definition for a specific class of Ethernet cables. Each Category has its own characteristics in terms of number of pairs, type of shielding, bandwidth (measured in MHz) and maximum data rate (measured in bits per second). Each Category can be used for transmitting one or more Ethernet types like 10BaseT, 100BaseT, 1000BaseT...
