5.5mm x 2.1mm DC Power Extension Cable 12V

A 12V DC extension harness with a 5.5mm x 2.1mm barrel plug on one end and the matching jack on the other. It moves a power supply away from the device it feeds, which matters when the adapter is bigger than the space behind the appliance.

  • Standard 5.5mm x 2.1mm barrel fits the common 12V adapter size
  • 1.2 M of reach lets the adapter sit at the outlet instead of behind the device
  • Moulded barrel ends resist the side loads that crack soldered joints
  • Polarity held consistent end to end so the load sees the correct supply

Samples ship within 3 days of confirmation. Bulk lead time is typically 7 to 12 days.

Problems It Solves

  • Adapter bricks block adjacent outlets and strain the socket
  • Short factory leads force the power supply into a cramped space
  • Reversed polarity on generic leads damages the load

Who It Is For

  • Security installers
  • Lighting and signage assemblers
  • Device makers bundling a power lead

Application Scenarios

  • CCTV cameras fed from a distant power supply
  • LED lighting and signage
  • Desktop appliances where the adapter blocks the socket
  • Bench testing of 12V devices

Technical Features

  • 5.5mm outer and 2.1mm inner barrel
  • Male plug to female jack
  • 1.2 M length
  • Moulded transitions

Values shown are the standard build. Connector family, conductor gauge, circuit count and finished length are all build options.

Quality Control And Certification

  • Continuity And Circuit Verification. Verifies the physical arrangement sequence of the harness terminals and the circuit topology between them
  • Circuit Configuration Verification. Confirms that a complete, uninterrupted current flow path exists within each circuit
  • Terminal Retention Strength Test. Measures the mechanical reliability of the connection between the terminal and the wire
  • Ingress Protection Rating Test. Evaluates the dust and water resistance sealing performance of harness connectors

The company is certified to IATF 16949 and UL standards. Samples are confirmed prior to trial or mass production, and the approved sample is the reference for every repeat order.

Customization Options

  • Connector family and terminal type to your part numbers
  • Conductor gauge selected from the current per circuit
  • Finished length and breakout positions to your drawing
  • Jacket colour, marking and labelling to your scheme
  • Packing to your instruction, PE bag and carton as standard

Compared With The Alternatives

Screw terminal DC adapters

A moulded lead has no exposed terminals to short against a chassis

Longer AC cords

Extending on the DC side keeps mains wiring inside the certified adapter

Use Guide

  • Confirm polarity, centre positive is standard on this build, before connecting the load
  • Do not coil the full length tightly behind hot equipment
  • Check the current draw against the conductor rating on long runs
