Typical applications
What an ethernet slip ring is
An Ethernet slip ring is a rotary joint designed to pass industrial Ethernet, such as 100 Mbit/s or gigabit links, through continuous rotation without unacceptable packet loss. The data rings are laid out as matched pairs with controlled impedance, short stubs and screening from power rings, and the brushes are chosen for low, stable contact resistance. Some units use contactless capacitive, inductive or optical channels for the highest rates. Most combine the Ethernet channels with power and discrete signal rings in one housing.
When engineers choose an ethernet slip ring
Choose an Ethernet slip ring when the rotating part carries cameras, drives, remote I/O or sensors on a network, which cuts the ring count compared with hard-wiring every signal. It suits indexing machines, packaging turrets and gimbals running EtherCAT, PROFINET or EtherNet/IP. The trade-offs are cost and validation: contact rings add small resistance changes, and gigabit links are more sensitive than 100 Mbit/s. For very high data rates, long life or high speed, a fibre optic or contactless channel may be better.
How to specify the Servotecnica SVTS C 04 / C 05 / C 06 Ethernet
Send these with your enquiry and an engineer can confirm the right SVTS C 04 / C 05 / C 06 Ethernet variant or an equivalent:
- Protocol and data rate, such as EtherCAT, PROFINET or gigabit Ethernet
- Number of Ethernet channels and pairs per channel
- Required test standard or bit error rate target
- Power circuits and current per circuit (A)
- Speed (rpm) and expected life (revolutions)
- Cable type and connectors on each side, such as RJ45 or M12
- Cable lengths to the nearest switch or node (m)
Common mistakes to avoid
- Specifying gigabit when the network only needs 100 Mbit/s, which adds cost and complexity
- Ignoring the cable runs on each side, which count towards the total channel length and loss
- Routing motor power next to data rings without screening or separation
- Not testing the full link with the real protocol under rotation before production
Servotecnica SVTS C 04 / C 05 / C 06 Ethernet: frequently asked questions
Can you help replace Servotecnica SVTS C 04 / C 05 / C 06 Ethernet or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Servotecnica SVTS C 04 / C 05 / C 06 Ethernet?
Through-bore slip rings integrating 100BaseT or 1000BaseT Ethernet with power and signal rings in 25.4 to 50 mm bores. Published series figures include circuits 65, current per circuit 20 A, voltage 600 V, speed 500 rpm. It is made by Servotecnica SpA; Specify Motion can help source it or propose an equivalent.
Who makes the Servotecnica SVTS C 04 / C 05 / C 06 Ethernet?
The Servotecnica SVTS C 04 / C 05 / C 06 Ethernet is made by Servotecnica (Servotecnica SpA) and is listed here for engineers comparing options. Specify Motion is not affiliated with Servotecnica SpA; brand names are used only to identify the product.
What is the circuits of the Servotecnica SVTS C 04 / C 05 / C 06 Ethernet?
The published series maximum circuits is 65. Individual models and sizes in the SVTS C 04 / C 05 / C 06 Ethernet range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the Servotecnica SVTS C 04 / C 05 / C 06 Ethernet?
We can assess suitable replacement options. Our engineers can review the original model and propose options for your load, speed and environment. An engineer confirms the fit against your application before recommending anything.
Can EtherCAT and PROFINET run through a slip ring?
Yes, when the slip ring is designed for it. Real-time protocols are sensitive to link drops, so the data rings need controlled impedance, good screening and stable contact resistance. Tell the supplier the protocol, cycle time and number of nodes on the rotating side, and test the full network under rotation. Many suppliers validate their Ethernet rings against standard cabling test methods.
What is the difference between a contact and a contactless Ethernet slip ring?
A contact slip ring passes the signal through brushes on rings, which is economical and handles 100 Mbit/s and often gigabit links well. A contactless channel uses capacitive, inductive or optical coupling, so there is no wear on the data path and very high rates or speeds are possible. Contactless channels cost more and usually still need contact rings for power.
