How to Select the Right Pins for UP01 Series Lightweight Connectors
Choosing the correct pin configuration ensures reliable connectivity and performance.
Determine Contact Requirements: Define the number of contacts needed for your application (e.g., 2–9 contacts for power/signal transmission).
Check Contact Diameter (øA): Match pin diameter with the required current-carrying capacity and signal needs using the selection chart.
Match Cable Size: Ensure the chosen IP68 compact plug supports your cable’s outer diameter and conductor size (AWG range).
Application Fit: Choose between solder or crimp contacts based on your assembly and installation requirements.
Environment & Standards: Select Short cable plug rated for IP68 waterproofing and compliant with IEC/RoHS for your target environment.
Tip: Use the Model Selection Table below to quickly identify the correct mil spec plug configuration based on your contact count and cable size.
