Rotating Slip Ring

Product Overview

A Rotating Slip Ring is an advanced electrical connector designed to provide continuous transmission of power and signals in rotating equipment. Through high-precision brushes and conductive rings, it enables uninterrupted electrical transmission during rotation, solving the problem of traditional cables tangling or wearing out after a limited number of turns. Rotating Slip Rings are widely used in radar systems, satellite antennas, medical devices, industrial automation machinery, robots, and wearable devices that require continuous rotation.

Key Features with Technical Data

1. Infinite Rotational Capability

Rotating Slip Rings support continuous 360° rotation, with rotation speeds up to 300 rpm or higher, avoiding cable tangling and damage. In satellite antennas, radar systems, or rotating worktables, equipment can perform full-angle scanning while ensuring stable signal and power transmission.

• Technical Data Example: Maximum rotation speed 300 rpm; continuous operation over 50,000 hours

• Advantage: Ensures uninterrupted operation without the need to replace cables

2. Multi-Channel Integration

Rotating Slip Rings can integrate dozens to over 100 channels to transmit multiple types of signals simultaneously:

• Power Transmission: Each channel supports up to 10A

• Data Transmission: Supports high-speed Ethernet, RS485, CAN bus

• Video Signals: Supports high-definition HDMI or SDI video data

For instance, CT scanners or industrial robotic arms require simultaneous transmission of power, imaging data, and control signals. Rotating slip rings’ multi-channel design fully meets these complex requirements.

• Technical Data Example: Single ring supports up to 100 channels; maximum bandwidth 1 Gbps

• Advantage: Enables multi-task simultaneous transmission, improving device efficiency

3. High Reliability and Longevity

Advances in materials and manufacturing have greatly improved the performance of rotating slip rings:

• Brush Material: Gold alloy brushes with a wear rate only 1/10 that of traditional carbon brushes, with a lifespan of 50,000–100,000 hours

• Conductive Ring Surface: High-purity gold plating resists oxidation and corrosion, ensuring long-term stable operation

This high reliability ensures stable signal and power transmission even in industrial environments with high humidity, salt, or corrosive conditions.

4. Compact and Lightweight Design

Micro versions of rotating slip rings can have diameters as small as 10 mm and weigh only a few grams, while still supporting 10A current transmission, ideal for drones, micro-robots, and wearable devices.

• Advantage: Reduces rotational inertia, improving system response speed

• Applications: Micro rotating machinery, robotic joints, drone gimbals

5. Strong Environmental Adaptability

Rotating slip rings operate reliably under extreme conditions:

• Protection Level: IP68, suitable for underwater operation

• Operating Temperature: -50°C to +150°C

• Applications: Deep-sea exploration devices, polar research stations, high-temperature industrial environments

This adaptability allows rotating slip rings to be used not only in industrial and medical equipment but also in specialized scientific research and outdoor applications.
