DC Jack Connector Pair with Wire – Male & Female 5.5 x 2.1mm

Description

The 5.5 x 2.1mm DC Jack Connector Pair offers a simple way to add a detachable DC power connection to an electronic project. The set includes matching male and female connectors, so users can connect and disconnect power without soldering the connectors together permanently. Moreover, each connector has attached red and black wires for easy circuit integration. Therefore, the pair suits prototypes, repairs, LED installations, security systems, and low-voltage power projects. Key Features Includes matching male and female DC connectors Standard 5.5mm outer diameter Standard 2.1mm inner contact diameter Supplied with attached red and black wires Creates a removable DC power connection Reduces installation and repair time Compact and easy to integrate Suitable for many low-voltage DC projects Useful for prototyping and maintenance work Technical Specifications Product Type: DC Barrel Connector Cable Pair Connector Size: 5.5 x 2.1mm Outer Diameter: 5.5mm Inner Diameter: 2.1mm Connector Types: Male Plug and Female Socket Number of Connectors: 2 Wire Colors: Red and Black Recommended Use: Low-Voltage DC Connections Connection Style: Plug-and-Socket Package Configuration: One Matching Pair Applications The connector pair suits projects such as: LED strips and lighting systems CCTV cameras and accessories Routers and network equipment Arduino and embedded projects DIY power supplies Battery-powered circuits Electronic repairs Prototype boards Low-voltage control systems Custom DC extension connections Installation Instructions First, disconnect the power supply. Then, identify the positive and negative contacts with a multimeter. Connect the wires to the corresponding points in your circuit. After that, insulate every soldered or joined connection with heat-shrink tubing or suitable electrical insulation. Finally, check the voltage and polarity before connecting sensitive equipment. Important Notes Confirm that both devices use a 5.5 x 2.1mm connector. A 5.5 x 2.5mm connector may look similar but may not provide a reliable connection. Do not determine polarity from the connector shape alone. Verify wire polarity with a multimeter before use. Do not rely only on the red and black wire colors. Check the required voltage and current of the connected device. Do not exceed the safe current capacity of the attached wires. Use this pair only with suitable low-voltage DC circuits. This product does not regulate or convert voltage. Keep all exposed wire joints properly insulated. Package Includes 1× 5.5 x 2.1mm Male DC Plug with Wire 1× 5.5 x 2.1mm Female DC Socket with Wire
