Product Description
The 2.1×5.5mm DC Power Jack Panel Mount Female Connector (V2) is a robust, chassis-mount barrel connector designed for secure, low-voltage power input on custom electronic enclosures, bench power supplies, and DIY project boxes. Featuring a standardized 5.5mm outer diameter and 2.1mm inner pin with durable threaded housing, it provides a stable connection for standard coaxial DC power plugs while preventing accidental pull-out.
Essential for project enclosures, battery chargers, and custom power distribution rigs, this Version 2 panel jack ensures reliable electrical contact and clean mechanical mounting.
⚠️ Polarity & Wiring Tip: Always verify your external power supply polarity (center-positive vs. center-negative) and solder your wires to the correct terminal lugs before fastening the jack to your metal or plastic enclosure.
Technical & Architectural Highlights
Standardized Dimensions: Precision 2.1mm center pin and 5.5mm barrel diameter ensure universal compatibility with standard DC power adapters.
Secure Panel Mount Design: Includes a threaded metal bushing and locking nut for firm, vibration-resistant mounting on project boxes and chassis panels.
Robust Solder Terminals: Features clearly accessible rear solder lugs for fast, permanent wire termination.
Insulated Washer / Nut: Provides mechanical stability and prevents electrical short circuits against conductive metal panels.
