Ethernet Slip Rings for Gigabit Data Across a Rotating Joint
An Ethernet slip ring — also called a network slip ring or RJ45 slip ring — carries 10/100/1000 Base-T traffic through a rotating interface together with the power rings that feed the rotating side.
All 77 Ethernet Slip Rings Models
Listed in full, each with its own parameter table.
What This Family Is For
The constraint
A twisted pair will not tolerate continuous rotation, and a poorly built rotating joint shows up as packet loss, crosstalk and a link that drops to 100 Mbit under vibration.
How INGIANT answers it
The DHS series is developed for 250 MHz transmission and carries 1–2 Gigabit Ethernet channels alongside 1–30 power rings at 2–20 A. Fibre brush bundle contacts, precious metal rings and aluminium housings hold insertion loss, return loss and crosstalk inside spec.
Who buys this family
Integrators of industrial robots, wind turbine control systems, radar and antenna platforms, machine vision stations and networked inspection equipment.
Standard Values Across This Family
These are the catalogue values that appear on most models in this family. Every one of them can be changed on a customised build.
Rotating speed
Catalogue units are rated 0–600 rpm. Lower and higher speed designs are built to order.
Working temperature
-40 °C to +65 °C on standard builds, with wider ranges designed against the application.
Protection level
IP54 as standard, with sealing grades up to IP68 where the environment demands it.
Insulation
Insulation resistance ≥1000 MΩ at 500 VDC, insulation strength 1500 VAC at 50 Hz for 60 s.
Contact system
Precious metal ring and brush pairs with dynamic resistance variation below 10 mΩ.
Lead wire
Colour-coded Teflon insulated tinned stranded flexible wire, 500 mm + 20 mm as standard.

Ethernet Slip Rings Questions Engineers Ask
Will an Ethernet slip ring hold a Gigabit link while rotating?
Yes. The DHS Ethernet series is designed for 250 MHz signal transmission and carries 1–2 channels of Gigabit Ethernet with stable transmission and no packet loss.
Which cable and connector types are available?
RJ45 male and female connectors are standard, with M12, CAT5E and CAT6 cable options.
Can Ethernet and power share one slip ring?
Yes. Ethernet channels are combined with 1 to 30 power rings rated 2–20 A, and the ring count and current can be adjusted for the application.
