The DC-005 Male Barrel Connector Plug (5.5mm x 2.1mm) is the industry-standard power connector for low-voltage electronic devices. At Electrapac, we recommend this high-quality plug for hobbyists and professionals building custom power cables, battery packs, or DIY power supplies for Arduino and CCTV systems.

Product Overview

The DC-005 male plug is designed to fit perfectly into the common 5.5mm x 2.1mm female sockets found on most electronics. It features a robust plastic screw-on cover (boot) that provides excellent strain relief for your wires. Inside, the solder terminals are clearly separated to prevent short circuits, making it easy to assemble even for beginners.

Key Features for Electrapac Customers

• Universal Standard Size: The 5.5 x 2.1mm dimension is the most common size used globally for 12V adapters, routers, and LED strip controllers.

• Durable Strain Relief: The screw-on housing features a flexible tail that prevents the wire from snapping or fraying at the connection point during frequent use.

• High Conductivity: Built with nickel-plated copper contacts to ensure a stable, low-resistance connection that prevents voltage drops and overheating.

• Easy Assembly: No special crimping tools are required. Just a standard soldering iron is needed to attach your wires to the internal lugs.

• Heat Resistant Insulation: The internal plastic spacers are designed to withstand the heat of soldering without melting or shifting.

Wiring & Assembly Guide

When soldering your Electrapac DC plug, it is vital to follow the standard "Center Positive" convention used by 99% of modern electronics:

1. Long Lug (Outer Sleeve): This is the Negative (GND) terminal.

2. Short Lug (Center Pin): This is the Positive (+) terminal.

3. Assembly Tip: Always slide the plastic screw-on cover onto your wire before you solder the pins to the terminals!

Pro-Tip: For a professional finish, use a small piece of Heat Shrink Tubing over each solder joint before closing the plastic cover. This adds an extra layer of insulation and prevents the wires from touching each other if the cable is pulled.

Primary Applications

• CCTV Camera Installation: Customizing the length of power cables for security cameras.

• Arduino & Robotics: Building battery-to-barrel-jack cables (connecting a 9V battery or LiPo pack to an Arduino Uno).

• LED Strip Lighting: Connecting 12V power adapters to LED controllers or DIY strip segments.

• Router & Modem Repair: Replacing broken or loose power plugs on networking equipment.

• Portable Power Supplies: Creating custom cables for bench power supplies or solar charging kits.
