Dc Power Jack Female Connector With Nut

DC Power Jack Female Connector with Nut (Panel Mount 5.5mm x 2.1mm) is a robust, chassis-mountable coaxial power socket designed to provide a secure, professional DC power input port for custom electronics enclosures, control panels, and project boxes. Featuring a threaded metal barrel and a tightening mounting nut, this female connector mounts firmly onto plastic or metal project boxes without requiring complex hardware brackets. Equipped with solder eyelets and internal spring-loaded contacts, it delivers a stable, low-resistance electrical connection for standard 5.5mm x 2.1mm DC power plugs used in 9V, 12V, and 24V power systems.

Features

• Industry-standard 5.5mm outer sleeve and 2.1mm center pin dimensions compatible with standard DC power adapter plugs
• Panel-mount threaded body design complete with a matching metal locking nut for secure chassis installation
• Built-in internal spring contact maintaining firm pressure against the inserted male plug center pin for uninterrupted power flow
• Clearly identified solder terminals (Positive center pin and Negative outer sleeve contact) for clean wiring
• Heavy-duty molded thermoplastic insulation housing combined with a nickel-plated metal barrel for corrosion resistance
• Safely supports continuous low-voltage direct current (DC) loads up to 5A
• Provides a professional, finished appearance for DIY enclosures, battery boxes, and test equipment

Applications

• Power input sockets for custom Arduino project enclosures, IoT sensor boxes, and robotics controller housings
• 12V/24V power distribution panels, battery chargers, and benchtop power supply units
• CCTV security camera power boxes, LED driver controller enclosures, and audio amplifier chassis
• Polytechnic diploma, university engineering thesis, and DIY electronics hardware assemblies

Important Notes:

• Panel Hole Drilling: Use an 8 mm drill bit or a step drill bit to create the chassis mounting hole. Ensure the mounting surface is flat so the locking nut tightens down flush and secure.
• Soldering Heat Caution: When soldering wires to the rear metal eyelets, work quickly (applying the soldering iron for 2 to 3 seconds) to prevent melting the internal plastic housing and misaligning the contact pins.
• Polarity Check: Double-check your internal power wiring before connecting power. Standard convention dictates that the center pin terminal connects to the Positive (+) rail and the outer sleeve terminal connects to Ground/Negative (-).
• Current Rating Limits: While rated for up to 5A, avoid running continuous high-amperage loads near the absolute limit for extended durations to prevent terminal heat buildup.

Package includes

• 1 x DC Power Jack Female Connector (5.5mm x 2.1mm Panel Mount)
• 1 x Metal Locking Nut
