Is this connector compatible with 4-pin RGB LED strips?

No, this is a 3-pin connector specifically for 3-wire addressable (digital) LED strips that use V+, GND, and a single Data line, such as WS2811 or WS2812B.

What does the 'locking clip' do?

The external clip on the male connector snaps over a tab on the female housing, securely locking the two halves together. This prevents them from pulling apart accidentally.

Can I use this to connect a strip to an addressable controller?

Yes, this is a common use. You can connect one end to your addressable LED strip and the other to the output of compatible addressable dream color controllers.

What is a JST SM connector?

JST SM is a common type of wire-to-wire connector used in electronics and LED lighting, known for its reliability and the secure connection provided by its housing and locking mechanism.

Application Scenarios

Extended Linear Lighting Runs Ideal for long installations in coves, hallways, or architectural accents where voltage drop can degrade light quality. Use these connectors at joints to easily tap in power from a secondary LED power supply, ensuring uniform brightness from start to finish.

Custom Digital Signage & Art When building complex LED matrices or custom-shaped fixtures with addressable LED strip lights, these connectors provide secure, modular connection points. The separate power wire simplifies wiring, especially when powering multiple segments from a central busbar.

Repair and Retrofitting Perfect for replacing damaged connectors on existing 3-wire addressable strips or for upgrading a setup to include more robust power injection points without needing separate splitter components.

How to Use This Connector Set

Ensure the power is disconnected before making any connections.
Identify the corresponding wires on your LED strips or controller. For the 3-pin connector, match the positive (V+), ground (GND), and data (DI/DAT) lines.
Connect the wires by soldering or using appropriate wire connectors, ensuring a secure electrical connection. Follow the color code: Red to V+, White to GND, Green to Data.
For power injection, connect the separate 2-pin red and white wires to your LED power supply, matching positive to positive and negative to negative.
Firmly push the male and female JST connectors together until the external locking clip clicks into place.
Restore power and test the connection and lighting effects.

⚠ Precautions

Always verify the voltage of your power supply matches the requirements of your addressable LED strip lights.
Double-check wire polarity before applying power to avoid damaging your LEDs.
This is not a waterproof connector. For outdoor or wet environments, ensure connections are properly sealed and protected.
For complex setups, it is helpful to understand how to wire addressable LED strip lights to manage data and power correctly.
