Description

The Male 12V DC Power Connector is the factual standard of the 12V power connections in practice, which is the 5.5 mm (outer) x 2.1 mm (inner) DC barrel plug. This is a pack of 10 male DC connector plugs which are sufficient spares when it comes to the installation or repair of CCTV cameras, LED strip lights and other low-voltage gadgets. The Male 12V DC Power Connectors are compatible with any regular 12V DC power socket (centre-positive, 2.1 mm centre pin), which means that they are perfect in the UK security and lighting systems. A spec-driven breakdown including details follows below:

Specifications of Male 12V DC Power Connector:

  • Size: Inner diameter 1 mm, outer diameter 5.5 mm (centre pin).
  • Voltage/Current Rating: Operation is designed to operate on circuits that are 12 V DC (up to a safe 16 V DC) with a max of around 1 A.
  • Polarity: Centre-positive design – the inner pin is positive, similar to standard UK 12 V DC supplies.
  • Contacts and Finishes: Brass contact pins, nickel electroless nickel plated; This offers good conductivity and resistance to corrosion. The black barrel case contains tough PBT plastic (depicted as a strong plastic barrel), which makes it durable and insulated.
  • Construction: A moulded strain relief is on the cable end of each plug to eliminate flex fatigue. Its barrel length is ≈9.5 mm with good depth of contact. Termination is solder-type (wire-mount), whereby the wires are soldered to the connection into the plug to provide a durable and firm connection.
  • Operating Temperature: Continuous operation from –30 °C to +70 °C; can be used indoors or in the sheltered outdoors. Contacts that are coated in nickel are water-resistant and wear-resistant.
  • Pack Contents: 10 Male 12V DC Power Connectors of the same type. With a 10-pack, you will always have connectors to various devices or backups available to you.

Applications of Male 12V DC Power Connector:

  • Applications: Typically used with whatever device has a 5.5×2.1 mm DC socket – common examples are UK CCTV/security cameras, LED strip lighting power supplies, routers, small fans and DIY electronics. The plugs (5.5 x 2.1 mm) are (CablesAndKits actually states) ideal when dealing with CCTV, LED lighting and low-voltage electronics.
  • UK 12 V Systems: These are plugs that are compatible with British 12 V DC conventions (e.g. domestic security and automotive 12 V). They readily couple with conventional UK 12 V adapters (centre-positive).
  • Flexibility: Repair or stretch power cables – just solder wire to the plug connector. They are also applicable to hobby applications (Arduino, small robotics) which need a 12 V DC barrel connector.

Material & Durability

  • Corrosion Resistance: Nickel-plated brass eat-through contacts inhibit oxidation, therefore guaranteeing longevity and dependable conductivity.
  • Housing: The Black PBT plastic body is not easily affected by impact or fire. It is resistant to normal shop and field environments.
  • Strain Relief: Built-In moulded relief helps to decrease cable strain and avoid joint breakage.
  • Temperature Range: Operates from -30 to 70°C to give strong performance in diverse UK conditions.

FAQs

What exact size is a “12V DC male barrel connector” in a typical 10-pack, and will it fit my device?
The majority of 12 V DC barrel plugs available in bulk (and some, including 10-packs) are in the 5.5 mm outer, 2.1 mm inner (5.5x2.1 mm) size, though a few vendors do offer 5.5x2.5mm. It is always important to look at the listing/specifications or verify the size of your jack; a 2.1 mm diameter differs by a slim margin, though it cannot be relied upon.
What’s the difference between 2.1 mm and 2.5 mm — can I force one to work?
Their appearance is almost similar, with the 0.4 mm difference in ID count. Certain plugs can loosely fit the other size but you run a chance of poor contact, sporadic wear. When it is not clear use an adapter or purchase the right ID – do not force it to fit.
Which way is the polarity — is the tip positive or negative?
No standard; most consumer 12 V barrel plugs are of the type known as tip positive (centre = +, sleeve = −) – although you need to check on the device or the power supply since there are exceptions. Label the polarity of the wire when wiring up or purchasing a replacement so as to avoid fried-up electronics.
How do I wire or solder these male plugs safely for my project?
Move a piece of cable portion, strip it, tin the wires, and solder the centre conductor to the inner contact of the plug and the outer/shield to the outer contact on the barrel. First of all, test polarity using a multimeter, then plug it into your device. You may not be a comfortable soldier and in this case, you can use pre-wired leads or visit a shop to avoid errors.
What current and voltage can a typical 12V DC male barrel plug in a 10-pack handle?
12 V 5.5x2.1 mm Generic plugs of 5.5 x 2.1 mm are typical of 12 V and usually range between approximately 1 A and 5 A, depending on the quality of construction – consult the vendor specifications. To ensure greater current pick, use plugs and cables with higher amp ratings for high-current devices (LED strips, large routers).
Are bulk 10-packs worth buying? Any tips when ordering?
Yes—10-packs are useful as spares, for small installations, or for hobby work. When placing an order: (1) check the precise ID (2.1 vs 2.5), (2) verify the polarity and current rating in the listing, (3) consider nickel-plated contacts or strain relief if durability is needed, and (4) if you have mixed gadgets, use a small adaptor set instead of excluding the plugs.
