24 Wire Slip Ring

Product Overview

24 Wire Slip Ring is an electromechanical device used for rotating equipment, whose main function is to transmit electrical energy, signals, or data between fixed and rotating components. Its core structure consists of 24 independent conductive rings (usually made of copper alloy or precious metal materials) and matching brushes (carbon brushes or metal brushes), which achieve continuous transmission of current or signals through the sliding contact between the brushes and the conductive rings. Slip Rings are usually separated by insulating materials to ensure electrical isolation between channels.

working principle

When the rotating device rotates, the conductive ring of the 24 Wire Slip Ring rotates synchronously with the rotating component, while the electric brush is fixed at the stationary end. The electric brush is in contact with the conductive ring through spring pressure, thereby maintaining electrical connection during rotation and avoiding wire breakage due to twisting. The 24 wire design means that 24 independent signals or power can be transmitted simultaneously, making it suitable for scenarios that require multi-channel parallel transmission.

Key Features

Multi channel integration capability

Supports the simultaneous transmission of 24 independent signals or power, and can integrate complex signal requirements from multiple sensors, servo motors, encoders, and other devices to achieve parallel transmission of power, data, and control instructions.

High performance and stability

Low friction design: using carbon graphite brushes (self-lubricating) or precious metal brushes (low contact resistance), combined with optimized sealing structure (IP65/IP67 optional), to ensure small torque fluctuations and stable signal transmission during rotation.

Long life guarantee: The lifespan of the electric brush can reach over 1 billion revolutions per minute, and the maintenance free design reduces downtime, making it suitable for industrial continuous operation environments.

Anti interference technology: The surface of the conductive ring is treated with silver/gold, and the insulation layer is made of polyimide material, effectively isolating EMI/RFI interference and ensuring the integrity of high-frequency signals.

Wide adaptability and customization

Flexible parameters: speed range of 0.1~5000 RPM, single channel current of 1~100A, voltage support of 600V AC/DC, compatible with DC to GHz level signal transmission.

Adjustable structure: Modular design supports customization of outer diameters ranging from 15 to 150mm, with optional cable lengths, connector types (such as MIL-C-5015, Lemo), and outgoing methods.

Durable and compact

Lightweight structure: weighing only tens of grams to several kilograms, suitable for space constrained scenarios.

Environmental tolerance: Designed for wear resistance and earthquake resistance, it can adapt to temperatures ranging from -40 ℃ to+85 ℃, meeting the high demands of harsh environments such as wind power, petroleum, and military.

Product Parameters

Major Function 

Power transmission

Provide power to rotating equipment such as industrial robotic arms, wind turbine pitch systems, rotating stage lighting, etc.

signalling

Analog signals: sensors (strain gauges, thermocouples), analog videos (CVBS).

Digital signal: Ethernet（10/100/1000Mbps）、USB、RS-485/232。

High frequency signals: microwave (GHz level), fiber optic signals (requiring fiber slip ring coordination).

Data synchronization and control

Support real-time data collection (such as vibration monitoring of rotating machinery) and remote control command transmission.

Multi system integration

The 24 Wire Slip Ring integrates power, video, and control signals, simplifying device wiring complexity.

Precautions for use

Installation specifications

Ensure that the concentricity between the 24 Wire Slip Ring and the rotating shaft is less than 0.05mm to avoid abnormal wear of the brush caused by eccentricity.

Use a torque wrench to tighten the screws to the manufacturer's specified torque (usually 2-5N · m).

Load Matching

To avoid exceeding the rated current/voltage, instantaneous overload should not exceed 150% of the rated value (duration<1 second).

When transmitting high-frequency signals, impedance matching (such as 50 Ω or 75 Ω) is required to reduce signal attenuation.

dynamic equilibrium

High speed rotating applications (>2000 RPM) require a dynamic balance test (G2.5 or above) on the 24 Wire Slip Ring to prevent vibration damage.

Cable management

The outgoing cable should be firmly fixed to avoid torque pulling caused by rotation.

Power lines and signal lines need to be routed separately to reduce electromagnetic interference.

Emergency plan

Configure backup slip rings or redundant channels, and recommend dual loop parallel design for critical systems.

Regularly backup slip ring operation data (such as temperature, vibration) and monitor it in real-time through IoT sensors.
