Waterproof and Explosion-Proof Combined Slip Ring for 1080P Video Signals
This 1080P video signal waterproof and explosion-proof slip ring combines high-definition video transmission, power, and control signals, and features IP65 high protection and Exd IIB T4 explosion-proof certification. The product utilizes an aluminum alloy explosion-proof casing and integrates 3 channels of 10A high current, 2 channels of 485 communication, and 1 channel of 1080P high-definition video. It supports 220V operating voltage and 50 RPM rotation speed, providing a safe and reliable connection solution for rotating monitoring and control systems in environments with explosive gases, such as those found in the petroleum, chemical, and coal mining industries.
Key Features
- Industrial Explosion-Proof Safety Certification: Features an Exd IIB T4 explosion-proof rating, with an explosion-proof enclosure that effectively isolates potential internal electrical sparks, allowing for safe use in explosive gas environments of IIA and IIB classes, and T1-T4 temperature groups.
- High-Definition Video Stable Transmission: Integrates a dedicated 1080P high-definition video channel, ensuring stable, lag-free, and delay-free video signal transmission during rotation, meeting the needs of real-time visual monitoring in hazardous environments.
- IP65 High-Strength Protection: Provides complete dust protection and protection against low-pressure water jets, capable of withstanding on-site dust, oil, and washing conditions, ensuring long-term reliability of internal electrical connections.
- Multi-Signal Integrated Solution: A single device simultaneously handles power (3x10A), control (2x485), and visual (1x1080P) signal transmission, significantly simplifying the design of rotating interfaces for equipment in hazardous areas, reducing wiring complexity and failure risks.

Frequently Asked Questions
What is the specific meaning of the Exd IIB T4 explosion-proof rating?
Ex indicates explosion-proof, d indicates flameproof type, IIB indicates suitability for explosive gas environments of classes IIA and IIB (excluding mine methane), and T4 indicates that the maximum surface temperature of the equipment does not exceed 135℃. This certification indicates that the product can prevent internal sparks from igniting external gases.
How is stable, frame-loss-free video signal transmission ensured during rotation?
The product uses a dedicated video slip ring module internally, with optimized design for impedance matching and shielding against interference of high-definition video signals. This ensures that signal attenuation and noise are kept at extremely low levels during continuous rotation at 50 RPM, guaranteeing stable image quality.
Is the product suitable for outdoor or washable environments?
Yes. The IP65 protection rating means it is completely protected against dust ingress and can withstand low-pressure water jets from all directions, making it suitable for outdoor, dusty, or industrial environments requiring daily cleaning and washing.
