DC Power Socket

A DC power jack, also known as a DC power connector, is a component used for connecting a power source to an electronic device. It is a circular connector with an inner pin that carries the positive voltage and an outer ring that is grounded. DC power jacks are commonly used in a variety of electronic devices, such as laptops, power banks, routers, and cameras, among others.

DC power jacks connector come in different sizes and configurations, with the most common being the 2.0mm barrel connector. This type of connector has a 2.0mm inner pin and measures approximately 5.5mm in diameter. The 2.0mm barrel connector is widely used in portable electronic devices, and it is compatible with a range of AC-DC adapters and power supplies.

One of the advantages of using a Panel Mount DC power Jack is its reliability. Since the voltage and current are supplied through a dedicated connector, it eliminates the risk of accidentally unplugging or disconnecting the power source. Also, DC power jacks are designed to withstand frequent use, making them a reliable and durable solution for powering electronic devices.

A DC power jack with a 2.1 - mm "innie" (female) connector is a commonly used type of power input port for various electronic devices. Here's a detailed look at its features and applications:

Physical Characteristics

• The 2.1 - mm DC power jack has a cylindrical shape with an inner diameter of approximately 2.1 mm. The "innie" design refers to the female - type socket, which is recessed and designed to receive a corresponding male plug. The jack is typically made of metal - plated plastic or a combination of metal and plastic materials. The metal parts provide electrical conductivity, while the plastic housing offers insulation and mechanical support.

Electrical Specifications

• This type of power jack is designed to handle specific DC voltage and current ratings. Common voltage ratings include 5V, 9V, 12V, and 24V, although it can be used with other voltages depending on the device's requirements. The current - handling capacity usually ranges from a few hundred milliamperes to several amperes, depending on the size and construction of the jack. It's important to match the power supply's output voltage and current with the jack's specifications to ensure proper operation and prevent damage to the device.

Applications

• Consumer Electronics: Many portable electronic devices such as laptops, tablets, portable speakers, and gaming consoles use 2.1 - mm DC power jacks. They provide a reliable and convenient way to connect the device to an external power source for charging or continuous operation.

• Industrial Equipment: In industrial settings, some control panels, small - scale machinery, and automation devices utilize 2.1 - mm DC power jacks. These jacks offer a standardized power input for equipment that operates on low - voltage DC power.

• DIY Electronics Projects: Hobbyists and electronics enthusiasts often use 2.1 - mm DC power jacks in their projects. They are easy to install on printed circuit boards (PCBs) and can be used to power various custom - built electronic circuits, such as Arduino - based projects, robotics, and home - made audio amplifiers.

The 2.1 - mm DC power jack "innie" is a versatile and widely used connector that plays a crucial role in providing power to a diverse range of electronic devices and projects. Its standardized size and electrical characteristics make it a popular choice for both manufacturers and end - users in the electronics industry.
