Moog AC7195 replacement and alternative options
Use these supply-network options as a starting point for an engineering check. We can also help source the original Moog part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.
Slip rings with dedicated 100M or Gigabit Ethernet channels alongside power and signal circuits, offered in solid-shaft and through-bore forms.
| Published maximum | AC7195 | Ethernet Slip Ring |

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
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 Moog AC7195
Send these with your enquiry and an engineer can confirm the right AC7195 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
Moog AC7195: frequently asked questions
Can you help replace Moog AC7195 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 Motion Control Products options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Moog AC7195?
One-inch capsule combining multiple Ethernet lines, HD video and coax options with 2 to 10 A power circuits. Published series figures include circuits 43, current per circuit 10 A, voltage 240 V, speed 250 rpm. It is made by Moog Inc.; Specify Motion can help source it or propose an equivalent.
Who makes the Moog AC7195?
The Moog AC7195 is made by Moog (Moog Inc.) and is listed here for engineers comparing options. Specify Motion is not affiliated with Moog Inc.; brand names are used only to identify the product.
What is the circuits of the Moog AC7195?
The published series maximum circuits is 43. Individual models and sizes in the AC7195 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 Moog AC7195?
We can assess suitable replacement options. On published figures, Motion Control Products Ethernet Slip Ring is options to assess from our supply network. 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.
