Description
Product Description The Panel Mount DC Jack Female Barrel Socket (2.1mm x 5.5mm) is a highly reliable, chassis-mounted electrical connector designed to deliver secure DC power to a wide range of electronic projects and devices. Featuring a threaded metal or high-grade plastic body, it comes equipped with a fastening hex nut and washer, allowing it to be easily locked into place on any custom enclosure, control panel, or project box. With its standard 3-pin configuration, this socket supports a standard solder-tab termination, providing a stable power connection that resists vibrations and accidental tugs. Technical Specifications & Features Connector Type: Female DC Barrel Socket / Jack Base Inner Pin Diameter: 2.1 mm Outer Standard Diameter: 5.5 mm Mounting Style: Panel Mount / Chassis Mount with threaded body and hex nut Terminals: 3-Pin / 2-Terminal (includes a chassis/switched ground pin for auto-disconnect configurations) Voltage/Current Rating: Typically rated up to 12V–30V DC, 3A (varies slightly by specific manufacturer) Compatibility This is the most ubiquitous DC power format globally, making it natively compatible with countless power supplies and hardware configurations. Compatible Power Adapters (Plugs) Male DC Barrel Plugs (2.1mm x 5.5mm): Fits any standard wall-wart or brick power adapter featuring a matching 2.1mm inner diameter and 5.5mm outer diameter tip. Note: While a larger 2.5mm x 5.5mm male plug may physically fit inside, it will not make a reliable electrical connection with the 2.1mm center pin. Compatible Electronics & DIY Platforms Development Boards: Natively compatible with the external power needs of the Arduino Uno, Arduino Mega, and various microcontroller breakout shields. DIY & Robotics: Ideal for custom enclosures housing Raspberry Pi power distribution boards, DIY audio amplifiers, and step-down buck converters. CCTV & Security: Extensively used as the replacement power base for security cameras, DVR units, and IR illuminators. LED Lighting: Seamlessly connects to 12V/24V LED strip light controllers, inline dimmers, and power injectors.
