LINKHIVE Fluidic/Pneumatic Circular Connectors: High-Performance Hybrid Solutions for Demanding Applications




Integrating Electrical and Fluidic Interfaces in One Compact Push Pull Connector – A Future-Proof Solution for Medical, Industrial Automation, and Underwater Systems

LINKHIVE proudly introduces its comprehensive range of fluidic/pneumatic circular connectors, delivering robust hybrid connectivity by integrating both electrical contacts and sealed pneumatic (fluid or gas) channels into a single push pull connector. Engineered to meet the evolving demands of precision medical devices, laboratory automation systems, industrial machinery, and underwater electronics, our hybrid series offers unmatched performance, space-saving benefits, and total design flexibility.

Through our commitment to engineering excellence, LINKHIVE’s fluidic circular connectors combine precision manufacturing, reliable sealing technologies, and the proven push pull self-latching mechanism to ensure quick, secure, and error-free connections—every time.




🌐 What Are Fluidic Circular Connectors?

Fluidic circular connectors, also known as pneumatic hybrid connectors, are designed to simultaneously handle electrical signal/power transmission and fluidic or pneumatic pathways (e.g., air, gas, liquid). These connectors feature internal channels with reliable seals that allow safe flow of fluids while maintaining high signal integrity in compact spaces.

They are especially beneficial in applications where multiple cabling types are traditionally needed, helping reduce clutter, minimize connection errors, and simplify equipment design.

🔧 Key Features & Advantages

1. Compact Integration

LINKHIVE’s connectors consolidate electrical pins and fluidic ports in one shell, eliminating the need for multiple separate interfaces.

2. Sealed Fluidic Channels

Our fluidic contacts are pressure-tested and designed to prevent leakage, backflow, or cross-contamination. Pressure resistance up to 6 bar is available.

3. Electrical Contact Versatility

  • 2 to 10 contacts

  • Signal or power transmission

  • Gold-plated brass or copper alloy pins

  • Support for AWG 16–28 cable sizes

4. Push Pull Locking

All models adopt the self-latching push pull mechanism—a fast, reliable, and intuitive way to connect and disconnect, even in tight spaces or under gloves.

5. Waterproof Ratings (up to IP68)

Selected models (e.g., FGG 3K, W108) support fully sealed operation in wet, dusty, or underwater environments.

6. Material Options

  • Metal (nickel-plated brass, stainless steel)

  • Plastic (medical-grade PBT, PEI)

  • Mixed materials for weight-sensitive designs

7. OEM/ODM Supported

We offer flexible customization:

  • Number and size of fluidic ports

  • Contact layouts and shell size

  • Overmolded cable assemblies

  • Company branding, packaging, serialization
