Multiple Contact Coaxial Signals Circular Push Pull Connectors EMC Shielding

High-quality connectors with multiple contact points for both coaxial and signal lines, combined with EMC shielding, are essential in applications where signal integrity, durability, and resistance to electromagnetic interference (EMI) are critical. These connectors are often used in specialized fields like military and aerospace, broadcasting, telecommunications, and high-end industrial systems. Below are the key aspects and options available for such connectors:

Key Features:

1. Multiple Contact Points:

   • Coaxial Contacts: These are designed to carry high-frequency signals such as RF (Radio Frequency) and microwave signals with minimal loss and reflection. The design ensures that the impedance is maintained throughout the connection, which is vital for signal integrity.
   • Signal Contacts: In addition to coaxial contacts, these connectors may include standard signal contacts for transmitting power, control signals, or data. The combination allows for the integration of multiple types of connections in a single interface.
   • Hybrid Configurations: Connectors can be configured to include both coaxial and signal contacts in various pin layouts, offering flexibility for complex systems requiring both high-frequency and standard signals.

2. EMC Shielding:

   • 360-Degree Shielding: Comprehensive electromagnetic compatibility (EMC) shielding protects against external EMI and prevents crosstalk between different signal types within the connector.
   • Enhanced Signal Integrity: The shielding ensures that sensitive signals, particularly high-frequency coaxial signals, are protected from external interference, ensuring reliable and accurate data transmission.

3. High-Quality Materials:

   • Metal Shell: Provides robust mechanical protection and further contributes to EMI shielding. Materials like stainless steel, aluminum, or brass are commonly used for durability and resistance to environmental factors.
   • Gold-Plated Contacts: Gold plating is often applied to the contacts to enhance conductivity, reduce resistance, and prevent corrosion, ensuring long-term reliability and performance.

4. Environmental Protection:

   • Sealing (IP67/IP68): These connectors are often sealed against dust, moisture, and other environmental contaminants, making them suitable for use in harsh environments, including outdoor and military applications.
   • Temperature Resistance: Designed to operate reliably across a wide temperature range, essential for aerospace and military applications.

5. Precision Engineering:

   • High-Frequency Performance: Coaxial contacts are precisely engineered to maintain consistent impedance and minimize signal loss, even at high frequencies.
   • Custom Configurations: Many manufacturers offer customizable configurations to meet specific application requirements, including custom pin layouts, special materials, or additional features like locking mechanisms.

Applications:

• Military and Aerospace:
  • Used in avionics, communication systems, radar, and other high-performance military equipment where reliable connections and signal integrity are critical.
• Broadcasting:
  • Employed in professional audio and video equipment where high-frequency signals and data transmission must be protected from EMI.
• Telecommunications:
  • Essential in base stations, satellite systems, and other communication infrastructure requiring high-frequency signal transmission with robust EMI protection.
• Industrial Automation:
  • Suitable for control systems and machinery where multiple signal types need to be transmitted reliably in environments with significant electrical noise.

Considerations for Selection:

• Frequency Requirements: Ensure the connector's coaxial contacts can handle the specific frequency range required by your application.
• Environmental Factors: Choose connectors with the appropriate IP rating and material specifications for your operating environment.
• Signal Integrity: Look for connectors with proven performance in maintaining signal integrity, particularly in applications involving high-frequency signals.
• Customization: If your application has unique requirements, consider working with manufacturers that offer custom solutions tailored to your specific needs.
