• Custom power supply distribution setups
• LED lighting installations

This connector may not be suitable for high-current applications exceeding the standard rating of typical 5.5/2.1mm barrel jacks. It is also not intended for outdoor use or environments with high moisture, as it lacks specialized weatherproofing and carries an IP20 rating.

Key specifications

• Connector type: DC barrel plug 5.5/2.1mm
• Cable length: 15 cm
• Protection rating: IP20
• Design: Pre-wired for direct integration

To use this connector, identify the positive and negative wires on the cable end. Strip the insulation from the wire ends and connect them to your power source or circuit board according to the polarity requirements of your device. Ensure that all connections are properly insulated, such as using heat-shrink tubing or electrical tape, to prevent short circuits. Verify that the voltage and polarity of your power source match the requirements of the device being powered before making the final connection.

What to consider before purchase

• Verify the required barrel jack size for your specific device
• Check the current and voltage ratings of your power supply
• Ensure the 15cm cable length is sufficient for your installation needs
• Confirm the polarity requirements of your equipment

For optimal performance and safety, always ensure that the wire connections are secure and properly insulated. Avoid bending the cable sharply at the connector base to prevent internal wire fatigue over time.
