This 5.5mm coaxial female barrel connector features a screw-terminal design that ensures a mechanically secure and electrically stable connection between your LED power source and your lighting system. The screw terminals accommodate standard wire gauges commonly used in low-voltage LED circuits, providing consistent contact pressure that minimizes resistance and prevents the voltage drop issues that can cause flickering or dimming in LED strip light installations.

Reliable connections are critical in any low-voltage lighting system because even small increases in resistance at a junction point can affect performance and generate unwanted heat. This connector is manufactured with durable contact materials designed to maintain electrical integrity over time, even in environments where temperature fluctuations occur — such as inside cabinetry, soffits, or enclosed cove lighting applications common in Canadian homes.

When planning your LED lighting project, it is important to ensure all components in your circuit — including connectors, wires, drivers, and LED modules — are properly rated and certified to Canadian electrical standards. Using quality connectors like this one helps maintain the safety and reliability of your overall system, supporting compliance with local electrical codes. Always ensure your complete installation is reviewed in accordance with cUL or CSA requirements where applicable.

Installation is simple and requires only a small flathead screwdriver. Strip approximately 5–7mm of insulation from your wire ends, insert the positive and negative leads into the correct screw terminals, and tighten firmly. Always verify polarity before powering on your system. This connector is ideal for use with LED strip lights, puck lights, and other low-voltage LED products that utilize a standard 5.5mm DC barrel plug connection.
