Overview
Stable signal transfer through continuous rotation.
Built for test rigs, automation systems and production equipment that need clean, uninterrupted electrical signals while they turn. Contact materials, sealing and leads are chosen for your circuits and environment.
Design advantages
- Power and signal rings in one assembly — ≤ 200 A power, ≤ 10 A signal
- Gold, silver or carbon-alloy contacts matched to each circuit
- Dynamic contact resistance variation < 0.01 Ω
- IP51 to IP67 sealing; cable or connector leads
- Circuit count, speed and service life built to your requirement

Electrical slip ring variants
Four builds of the same principle.
Low-frequency
Rugged multi-signal
Compact and sealed to IP67, with a proven anti-interference design. Up to 150 A; power, control, network and video signals; built for vibration, shock and damp heat.
Mid-frequency
RF through the joint
DC–600 MHz · isolation ≥ 45–70 dB · insertion loss ≤ 1 dB · phase variation ≤ 1–5° · bore 0–250 mm · ring pitch 10–30 mm — with power and other signals alongside.
Miniature
Small envelope, full data
Vacuum-potted, rings machined in one pass for 0.02 mm concentricity. Up to 10 A, 1080p video and Gigabit Ethernet; integrates with fiber-optic and RF joints.
High-speed
2,000 rpm, 300 g
Anodized aluminum housing with a gold-alloy core, carrying power, control, network and video signals.
Applications
Where it runs.
Test rigs
Instrumented rotating test stands that can’t tolerate signal dropouts.
Automation systems
Indexing tables and rotating axes carrying sensors and I/O.
Production equipment
Rotating machinery that needs power and signals on the same axis.
Radar and antenna pedestals
Combined with Gigabit Ethernet, fiber and coolant channels.
