How to Use This Waterproof DC Connector
- Turn off all power before installation.
- Identify the positive (+) and negative (-) wires on your LED strip and the connector pigtails.
- Connect the male connector's wires to your power source, such as an LED driver.
- Connect the female connector's wires to the input of your single color LED strip light.
- For a fully waterproof installation, splice the wires using waterproof methods like soldering followed by heat-shrink tubing or using waterproof wire nuts.
- Align the male and female DC connectors and push them together firmly to create a secure, watertight seal.
- 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.
