Cables Assemblies: FAQ

How do I ensure the connector pitch fits my PCB?

Always verify the 'pitch' distance (e.g., 1.25mm, 2.0mm, 2.54mm) listed in the specifications. A visual match isn't enough; measuring the distance between pins is crucial to avoid incompatibility.

How can I tell if the wire is real copper or aluminum?

Look for 'Tinned Copper' or 'Oxygen-Free Copper' in the product description for superior conductivity and soldering. Avoid 'CCA' (Copper Clad Aluminum) for high-current applications as it has higher resistance.

What specs indicate a durable cable assembly?

Check for 'Silicone Insulation' for high flexibility and heat resistance, or 'Shielded' cables to prevent signal interference. High strand counts in the conductor also indicate better flexibility and fatigue resistance.

Is shipping safe for delicate pin connectors?

Reputable sellers usually ship fragile assemblies in anti-static bags or rigid boxes. Check the seller's feedback images to confirm they use protective foam to prevent bent pins during transit.

Recommendations for buyers

✓
Verify Wire Gauge (AWG)
Ensure the American Wire Gauge (AWG) matches your current load requirements. Remember that lower numbers (e.g., 16AWG) mean thicker wires suitable for higher power, while higher numbers (e.g., 28AWG) are for low-signal data.
✓
Check Temperature Ratings
For automotive or industrial use, select cables rated for at least 105°C. PVC insulation is standard, but Silicone is required for environments with extreme temperature fluctuations.
✓
Connector Standardization
Identify the exact connector series (Molex, JST, Dupont, SMA) and gender (Male/Female) required. Pay close attention to 'Reverse Polarity' variants in RF assemblies.
