Description

Overview

A DC power socket and its matching plug in the common 5.5 x 2.1 mm and 5.5 x 2.5 mm barrel sizes, rated 3A at 12V. The socket builds carry an ON/OFF switch, and sockets and male plugs are listed separately.

Specifications

  • Barrel sizes: 5.5 x 2.1 mm (5521) and 5.5 x 2.5 mm (5525)
  • Rating: 3A at 12V DC
  • Variants: 5521 socket, 5525 socket, 5521 male, 5525 male
  • Switching: ON/OFF on the socket models
  • Stated use: charging interface for manual electric tools

Purpose

Power-tool charging inlets wear loose with use, and this socket replaces the inlet rather than the whole tool. The switch lets the port be isolated between charges, and both pin diameters are stocked because 2.1 and 2.5 mm plugs do not interchange.

Applications

  • Charging inlets on manual power tools
  • 12V chargers for RC gear and drones
  • LED lighting and CCTV power feeds
  • Bench supply output sockets
  • Repair of a loose device inlet

How to Use

  1. Measure the plug barrel: 5.5 x 2.1 mm takes the 5521, 5.5 x 2.5 mm takes the 5525.
  2. Settle polarity before soldering, since barrel and centre pin carry different rails.
  3. Solder the leads to the socket tabs and insulate both joints.
  4. Fit the socket, then check the ON/OFF position before a tool is plugged in.
  5. Caution: hold the load inside 3A at 12V, and note a 5525 plug will not seat in a 5521 socket.
