How to Select the Right Pins for ZGG Series Circular Metal Socket?

Confirm Plug Compatibility:
Ensure the selected ZGG socket matches the corresponding K Series plug (FGG / TGG) in size (00K / 0K / 1K / 2K / 3K), insert configuration, and keying (e.g., G key).

Determine Contact Requirements: Identify how many contacts you need for power and signal transmission (e.g., 2–32 pins).
Check Contact Diameter (øA): Ensure the selected pin diameter meets your current-carrying and signal needs using our pin chart.
Match Cable Size: Verify that the circular socket supports your cable’s outer diameter and conductor size (AWG range).
Metal socket Application Fit: Choose between solder, crimp, or PCB contacts depending on your installation type and performance requirements.
Consider Environment & Standards: Ensure High-current socket meets IP ratings and complies with IEC/RoHS for safe and long-term use.
