As electronics become smaller and more integrated, the role of these compact connectors continues to grow.
Key Features to Look for in a 2-Pin DC Power Connector
When choosing a 2-pin DC connector, consider factors that align with your voltage, current, and environmental requirements. Here’s what to prioritize:
-
Current Rating: Match your device’s power load (e.g., 3A, 10A).
-
Connector Type: Barrel, screw-type, or snap-fit.
-
Contact Material: Gold- or tin-plated for corrosion resistance.
-
Waterproofing: IP65/IP67 ratings for outdoor or marine use.
-
Polarity Markings: Visible + / − terminals avoid miswiring.
-
Temperature Range: Choose materials resistant to heat buildup.
Also, check for RoHS/UL compliance if safety or certification is required.
