Description

Overview

Female DC power jacks, the socket half of a barrel-plug pair, sold for DIY wiring and repair. The range spans three barrel sizes plus two narrow 3.5 mm multi-pole sockets, in waterproof bodies.

Specifications

  • Gender: female socket
  • Barrel sizes: 5.5 x 2.1 mm, 5.5 x 2.5 mm, 3.5 x 1.35 mm
  • Multi-pole: 3.5 mm, 3-pole and 4-pole
  • Body: waterproof jack

Purpose

Projects fail less for want of a jack than from a 5.5 x 2.1 plug meeting a 5.5 x 2.5 socket. Carrying all three barrels in one listing closes that gap.

Applications

  • Cracked inlet repair on routers and docks
  • LED strip and lighting tails
  • Bench supply and adapter leads
  • Robot chassis power inlets

How to Use

  1. Measure the plug with calipers first; 2.1 and 2.5 mm pins look alike by eye.
  2. Count poles on 3.5 mm parts, as a 3-pole plug will not seat in a 4-pole jack.
  3. Solder the tails, then tug-test each joint.
  4. Caution: the waterproof claim covers the jack body, not your solder joints or the rear opening. Seal those and stay within the circuit’s own ratings.
  5. Check centre-pin polarity on a meter before power-up.
