How to Select the Right Pin Configuration for C Series Watertight Circular Connectors
Selecting the correct pin configuration ensures that your C Series watertight Rugged connector perform reliably in demanding applications. Follow these key steps:
Define Your Application
Identify if the watertight circular male connector will be used in medical devices, industrial equipment, outdoor systems, or communication tools.
Consider environmental needs such as IP68 waterproofing, dustproofing, and vibration resistance.
Choose the Connector Type
Straight Plug (FGG S3/S4) – Ideal for cable collet or bend relief requirements.
Rugged connector (G4/G8) – Perfect for sealed panel-mount applications.
In-line Receptacle (K3/K4) – Designed for cable-to-cable connections.
Select the Right Series & Size
0C: Miniature for compact devices.
1C: Small size for medical and portable equipment.
2C: Medium size for industrial and field applications.
3C: Large size for high-density contact configurations.
Determine the Number of Contacts
Check the pin count (2–32 contacts) based on your signal and power transmission needs.
Verify Cable Compatibility
Match the connector to your cable’s outer diameter (see Cable Ø in our selection tables).
Check Standards & Testing
All connectors undergo electrical continuity, insulation resistance, sealing, and durability tests to meet IEC and RoHS compliance standards.
Tip: Use our Pin Configuration & Dimension Tables to quickly identify the ideal combination of contact count, insert type, and connector style for your project.
