Ideal for Demanding Environments

Outdoor LED Strip Lighting The perfect solution for creating a disconnect point or extending power to single color LED strip lights used on patios, decks, pergolas, and building exteriors. The waterproof design ensures your connections are safe from rain and sprinklers.
Landscape & Garden Lighting Use this durable connector pair to reliably wire low-voltage landscape spotlights, pathway markers, garden accents, and other outdoor fixtures. Its robust construction withstands burial and exposure to soil and moisture.
Marine & Low-Voltage Water Features Excellent for custom low-voltage lighting in marine applications, boat cabins, or near fountains and aquariums. The tinned copper wire resists corrosion in humid or salt-air environments, ensuring a long-lasting, stable connection.

How to Use This Waterproof DC Connector

  1. Turn off all power before installation.
  2. Identify the positive (+) and negative (-) wires on your LED strip and the connector pigtails.
  3. Connect the male connector's wires to your power source, such as an LED driver.
  4. Connect the female connector's wires to the input of your single color LED strip light.
  5. For a fully waterproof installation, splice the wires using waterproof methods like soldering followed by heat-shrink tubing or using waterproof wire nuts.
  6. Align the male and female DC connectors and push them together firmly to create a secure, watertight seal.
⚠ Precautions
  • This is a low-voltage DC connector. Do not use with high-voltage AC power.
  • Ensure your total power load does not exceed the current-carrying capacity of 18AWG wire.

Frequently Asked Questions

Q: Is this sold as a single connector or a pair?

A:This product is sold as a complete set, including one male DC barrel connector and one female DC barrel connector.

Q: What does 'DC 5.5*2.1mm' refer to?

A:It's the standard physical size of the connector plug: 5.5mm for the outer diameter and 2.1mm for the inner pin diameter. This is a very common size for low-voltage electronics.

Q: How waterproof is this connector?

A:The interlocking male and female barrel connection is designed to be waterproof. However, you must also use a waterproof method (like soldering and heat shrink tubing) to seal the wire splices.

Q: What is the advantage of 18AWG tinned copper wire?

A:18AWG is a relatively thick gauge that handles higher current with less performance loss (voltage drop) than thinner wires. Tinned copper provides excellent conductivity and superior resistance to corrosion.
