DC plugs and sockets
Regardless of the type of electrical device or system, as well as its purpose, each of them requires power supply. If they are equipped with power supplies, the functions are fulfilled by DC sockets. It is important that the connector and the power supply unit connected to it are compatible with each other, i.e. they fit together properly. It is important to pay attention to the key parameters that determine this, i.e. the shape of the plug, as well as the maximum operating current and voltage. We offer a wide range of sockets, which have been designed and created taking into account a specific type of power supply. In our store you will find sockets that fit most DC power supplies, so you can be sure that the chosen one will be compatible with the power supply. At the same time you can use the option of a power outlet adapter. This will allow you to combine different power sources and thus increase your design capabilities. The DC sockets and plugs differ in appearance, shape, parameters, number of pins and type, such as male, female and male-female.

Wide selection of power sockets
DC power sockets differ in many parameters. The basic ones are the maximum permissible operating voltage and the maximum current that can flow through the connector . These parameters affect the shape of the plug - the more current that has to flow through it, the larger it is generally to ensure lower resistance and reduce voltage drops. The operating voltage is related to the insulation used in the connector. This is extremely important because exceeding the permissible voltage for a socket or plug may lead to a breakdown and, consequently, a short circuit, which may damage both the power supply system and the powered device.
DC socket - Power connectors with various parameters
Typical power connectors are cylindrical in shape. There is a single pin in the center and the outer part of the plug is the second pole of the DC power supply. There are no standards specifying which of these two elements should have voltage and where the ground should be, however, in recent years it has been assumed that the middle pin of a plug or socket is the so-called "hot" - there is the plus of the power supply, while the outer part of the connector is at ground level. Plugs are characterized mainly by two parameters - length and diameter. This ensures that connectors can be easily matched to each other without the need to perform more complex measurements.
Universal power accessories
Our store's offer includes a wide selection of not only sockets and plugs, but also numerous accessories that allow them to be connected and used in any DC power systems to build a prototype. Examples include connectors terminated with ARK connectors or screw connectors. This allows for easy installation of the plug on cables, without the need for soldering. Additionally, there are also sockets available with goldpins that can be plugged into contact boards used for prototyping electronic devices.
DC sockets and plugs - FAQ
In the vast majority of cases, the positive (+) pole of the power supply is connected to the middle pin of the plug , and the negative (-) pole to the outer metal "sheath". However, please remember that there are exceptions to this rule (mainly in the world of music equipment).
The DC socket should be connected according to the polarity of the power supply associated with the device - usually the middle contact will be connected to the positive pole of the power supply, and the side pressure plate - to the negative pole. Many sockets also have a third contact, which allows, for example, automatic switching of the power supply between the external power supply and batteries .
DC sockets are used to connect constant voltage plug-in and desktop power supplies. They are used in everyday devices, toys, LED lamps , medical equipment and many others.
DC sockets are a wide group of connectors that are used to power low-power devices using external plug-in or desktop power supplies. The most common sockets are 2.1/5.5 mm and 2.5/5.5 mm.
