Circular push-pull connectors that integrate both air (fluid) and electrical signal transmission, along with EMC shielding, are specialized connectors designed for applications requiring multifunctionality in a compact, robust form. These connectors are typically used in advanced industrial, medical, and military applications where the combination of pneumatic control, fluid handling, and signal transmission in one connector is necessary.
Key Features:
-
Multiple Functionality:
- Air/Fluid Channels: These connectors are designed with integrated pathways for air or fluid transmission, allowing them to handle pneumatic control or fluid delivery alongside electrical signal transmission.
- Signal Contacts: In addition to air/fluid channels, the connectors include electrical contacts for transmitting data, control signals, or power.
- Hybrid Design: The combination of fluid and signal transmission in a single connector reduces the number of connections needed, saving space and simplifying system design.
-
EMC Shielding:
- 360-Degree EMC Protection: Comprehensive shielding is integrated into the connector design to protect sensitive electrical signals from electromagnetic interference (EMI), ensuring reliable operation in environments with significant electromagnetic noise.
- Enhanced Signal Integrity: The shielding also helps to prevent crosstalk between the different signals and functions within the connector, maintaining high-quality signal transmission.
-
Push-Pull Mechanism:
- Quick and Secure Connection: The push-pull mechanism allows for easy and rapid connection and disconnection, ensuring a secure and reliable connection that resists vibration and accidental disconnection.
- Ease of Use: Designed for environments where quick and reliable connections are essential, the push-pull feature allows for intuitive operation, even in tight or hard-to-reach spaces.
-
Robust Construction:
- Metal Shell: The connectors are typically housed in a metal shell, providing strong mechanical protection against impacts, vibrations, and environmental factors.
- Sealing Options (IP67/IP68): These connectors are often sealed to protect against dust, moisture, and other contaminants, making them suitable for use in harsh environments, including outdoor and industrial applications.
- Durability: Designed to withstand repeated connection cycles, these connectors are built for long-term reliability, even in demanding conditions.
-
Customizable Configurations:
- Variety of Pin and Channel Layouts: Depending on the application, these connectors can be customized with different numbers of signal contacts and air/fluid channels to meet specific requirements.
- Material Choices: Depending on the application, the connectors can be made from various materials, including stainless steel, aluminum, or high-grade plastics, to meet specific environmental or regulatory requirements.
Applications:
- Medical Devices: Used in medical equipment where air or fluid control (e.g., pneumatic control of surgical instruments or fluid delivery in dialysis machines) needs to be integrated with electrical signal transmission.
- Industrial Automation: Employed in systems requiring the combined transmission of signals and pneumatic control, such as automated machinery, robotics, and process control systems.
- Aerospace and Defense: Utilized in avionics and military systems where robust, multifunctional connectors are needed to handle both fluid (e.g., hydraulic or pneumatic systems) and signal transmission in harsh environments.
- Laboratory Equipment: Suitable for analytical instruments and lab automation systems where both fluid management and data transmission are necessary.
