Technical Specifications

Effortlessly create secure, weatherproof extensions for your lighting projects with the 3PIN-WTC-NW Male and Female Extension Connector. This connector set is specifically designed for 3-wire LED lighting systems and eliminates the need for soldering, making it perfect for quick and reliable field installations. Its key feature is the integrated solderless terminal block, which allows you to simply strip your wires, insert them, and tighten the screws for a robust mechanical and electrical bond. The M14 threaded coupling ensures a tight, waterproof seal, making it an ideal choice for extending connections on 3-wire systems like CCT tunable white LED strips or certain addressable LED strips in both indoor and outdoor environments.

Key Features

CCT Tunable White LED Strips Perfect for creating custom-length extensions for 3-wire CCT tunable white LED strips. The solderless design makes it easy to install strips in kitchens, coves, and architectural features without a soldering iron.
Marine & Automotive Projects Ideal for custom 12V or 24V lighting systems in boats, RVs, and other vehicles. The secure, vibration-resistant terminal connection and waterproof housing protect against moisture and the elements.
Custom Signage & Displays Simplify the wiring process for complex signs or displays using 3-wire addressable LED strips. The terminal block allows for easy assembly and maintenance, reducing installation time.

How to Use This Connector

  1. Step 1: Disconnect power to your LED strip.
  2. Step 2: Use a wire stripper to expose approximately 5-7mm of the three copper wires on your cable.
  3. Step 3: Loosen the small screws inside the connector terminal block with a Phillips or flathead screwdriver.
  4. Step 4: Insert each of the three wires into its respective terminal. Ensure the wiring order (e.g., V+, CCT, V-) matches on both the male and female connectors.
  5. Step 5: Tighten the terminal screws firmly to secure the wires. Gently tug each wire to ensure a solid connection.
  6. Step 6: To complete the waterproof connection, align the male and female plugs and screw them together until the O-ring is fully compressed and the connection is tight.
⚠ Precautions
  • Always disconnect the power supply before cutting or connecting wires.
  • Ensure the wire gauge is compatible with the connector's terminal block.
  • Double-check wire polarity and order before tightening the terminals to avoid damaging your LED strips.
  • Fully tighten the waterproof housing to ensure a proper seal for outdoor or damp applications.

Frequently Asked Questions

Q: What type of LED strip is this 3-pin connector for?

A:This connector is designed for any 3-wire LED lighting system, most commonly CCT tunable white LED strips and some addressable LED strips that use a V+, Data, and GND line.

Q: Do I need to solder wires to this connector?

A:No, this is a solderless connector. It uses a screw-down terminal block, so you only need to strip your wires and secure them with a small screwdriver.

Q: Is this connector truly waterproof?

A:Yes, when the male and female ends are fully screwed together, the internal O-ring creates a tight seal that protects the connection from water and dust, making it suitable for outdoor use.

Q: What tools are required for installation?

A:You will need a wire stripper to expose the ends of your wires and a small Phillips or flathead screwdriver to tighten the terminal screws.

Q: Can I use this for a 2-pin single color LED strip?

A:While you could technically use it and leave one terminal empty, it is not recommended. We offer a wide range of dedicated 2-pin connectors for single color strips for a more appropriate fit.

Q: What is the primary advantage of this terminal-style connector?

A:The main advantage is the ability to create a very strong and reliable connection in the field without needing a soldering iron, which is ideal for on-site installations.
