5.5 x 2.5 mm barrel connector: identification only

A 5.5 x 2.5 mm barrel identifier specifies two nominal diameters, not polarity, voltage or an approved replacement adapter.

Also called 5.5 2.5 5525 5.5mm 2.5mm DC plug 2.5 mm barrel bore

The same outside diameter can hide a different bore. Establish the complete device requirement before choosing power.

Look for

Use the documented 55-00050 assembly-type plug as an example, not a visual sizing gauge or a replacement recommendation.

What the evidence supports

The complete 55-00050 drawing supports a named mechanical example. It does not nominate a device or charger.

INSUFFICIENT MATCHING EVIDENCE

What not to conclude

Treating the 2.1 mm and 2.5 mm bore labels as identical loses a required measurement.

NOT ESTABLISHED

Before you choose a part

  1. Find the exact device’s connector and power specification.
  2. Read both diameters and the required exposed length.
  3. Use approved equipment guidance; do not try adapters to discover a fit.
Evidence for this decision · 3 source-scoped observations

C363A (private workspace) — Tensility drawing 55-00050 identifies an assembly-type DC plug with a 5.5 mm outside diameter and 2.5 mm bore.

Nominal identification using this exact product drawing; not a universal replacement specification. S484

C363B (private workspace) — The assembled view of Tensility 55-00050 labels its exposed barrel length as 12 mm.

Do not apply this length to every connector sold as 5.5 x 2.5 mm. S484

C363C (private workspace) — Tensility 55-00050 shows the connector, inner sleeve and outer sleeve as separate assembly components.

A connector component is not a power supply or an established wired polarity; no assembly instructions are provided here. S484

Manufacturer evidence is not an independent review, wiring assignment or hardware test.

Before you connect

What to check

  1. Stop at identification; use the device maker’s approved power supply guidance.
  2. Check the full model and power label rather than guessing from diameter.
  3. Do not infer voltage, AC/DC, polarity, current capacity or safety approval from fit.
