5.5 mm × 2.5 mm Male DC Power Plug — Long Type

Upgrade or repair your low‑voltage power connections with this Male DC Power Plug (5.5 mm OD × 2.5 mm ID). Designed for reliability and ease of assembly, it features a moulded strain relief, a durable plastic barrel, and solder termination for secure wiring. Ideal for powering Arduino and Raspberry Pi projects via compatible DC supplies, as well as other electronics components, modules, and microcontroller-based builds.

✅ Key Features

• 5.5 mm × 2.5 mm DC barrel plug (OD/ID) for common low‑voltage power adapters
• Long type with extended barrel for deeper jack engagement
• Moulded strain relief to protect cable from flex and fatigue
• Strong plastic barrel for dependable mechanical durability
• Solder termination for secure, low-resistance connections

📏 Specifications

• Connector type: Male DC barrel plug
• Dimensions: 5.5 mm outer diameter × 2.5 mm inner pin (OD/ID)
• Barrel length: 14 mm
• Termination: Solder contacts
• Body material: Strong plastic barrel with moulded strain relief

🛠️ Typical Applications

• Repairing or replacing plugs on mains adaptors
• Powering Arduino boards, development kits, and electronics modules via compatible DC inputs
• DIY wiring for microcontroller systems, sensors, and test rigs
• General low‑voltage DC projects using standard barrel jacks

⚙️ Compatibility Notes

• Matches devices and jacks that require a 5.5 mm OD × 2.5 mm ID plug.
• Ensure your device’s jack size and polarity before wiring. Do not assume center‑positive or center‑negative.
• For Raspberry Pi, use with compatible DC systems or peripherals that accept a 5.5 × 2.5 mm barrel jack (note: recent Pi boards use USB power inputs).

🧪 Assembly Tips

• Strip and tin the cable conductors before soldering to the plug terminals.
• Verify polarity and continuity with a multimeter before connecting to your device.
• Add heat‑shrink tubing for extra strain relief if needed.
