Choosing the correct socket configuration ensures full compatibility with your T Series plugs and reliable sealing in harsh environments.
Confirm Plug Compatibility:
Ensure the selected HMG socket matches the corresponding E Series plug (FGG / TGG) in size (00E / 0E / 1E / 2E / 3E), insert configuration, and keying (e.g., G key).
Determine Contact Requirements:
Identify the number of contacts required for your application (e.g., 2–32 pins), based on your power and signal distribution needs.
Check Contact Diameter (øA):
Match the pin diameter to the expected current load and signal transmission. Refer to the pin configuration chart for available options.
Verify Cable & Panel Fit:
Ensure the socket supports your cable outer diameter and meets panel-mounting dimensions for your enclosure.
Consider Sealing & Standards:
Confirm the connector meets IP68 sealing when mated and complies with IEC / RoHS requirements for long-term reliability.
