How to Select the Right Pins for AMC Series Circular Connectors
Choosing the right pin configuration is critical for achieving optimal performance in high-speed, ruggedized applications.
Define Your Contact Needs
Determine the number of contacts required for your application (e.g., 2–26 contacts) based on signal, power, or high-speed data transmission requirements.
Consider Data & Speed Requirements
For high-speed applications (Ethernet, USB, HDMI), refer to the connector’s high-speed POS options to ensure compatibility with CAT 6, CAT 5, USB 2.0, or HDMI standards.
Match Cable Size & Type
Verify that the connector supports your cable’s outer diameter and conductor size (AWG) to ensure secure termination and maintain signal integrity.
Select the Proper Keying Code
Choose from available key codes (A–D) to prevent mismating and simplify assembly in multi-connector setups.
Check Environmental Ratings
Ensure the connector meets your required IP68 sealing level, vibration/shock resistance, and MIL-spec compliance for military or outdoor use.
Evaluate Application Fit
Select between standard signal, power, or hybrid configurations depending on whether your system requires mixed-signal or high-current capabilities.
By carefully evaluating these factors and cross-referencing with the selection tables below, you can confidently choose the ideal AMC Series Y or TTA 2Y connector for your application.
