DC Power Jack Socket

A 2.0mm power jack socket is a type of connector used to provide power to electronic devices. It is commonly used in various applications such as electronic toys, audio equipment, and computer peripherals. The socket features a cylindrical shape with a diameter of 2.0mm and it comes with a central pin that is designed to fit perfectly into a corresponding socket.

• The 5.5x2.5mm Power DC Jack has a cylindrical shape. The outer diameter of the jack is 5.5mm, and the inner diameter of the center pin is 2.5mm. This size specification is a standard in the industry, ensuring compatibility with a wide range of power adapters and electronic devices.

Electrical Characteristics

• Voltage and Current Ratings: It is designed to handle specific DC voltages and currents. Common voltage ratings include 5V, 9V, 12V, 19V, etc., and the current - handling capacity usually ranges from 1A to several amperes, depending on the specific design and quality of the jack. For example, in a laptop with a 19V power supply, the 5.5x2.5mm DC power jack is capable of safely transmitting the required current to power the device.

• Polarity: The panel mount DC Power Jack typically has a specific polarity. The outer sleeve of the jack is usually the negative (-) terminal, and the center pin is the positive (+) terminal. This polarity convention is widely recognized and must be adhered to when connecting the power adapter to the device to ensure proper operation and prevent damage to the electronic components.

Applications

• Laptops: Many laptop computers use the female dc jack connector as the standard power input port. The power adapter provided with the laptop has a corresponding 5.5x2.5mm plug that fits into the jack to supply power to the laptop, charging its battery and powering the internal components.

• Tablets and Portable Media Players: Some tablets and portable media players also adopt this type of power jack for charging and powering. It allows for a convenient and standardized way to connect to external power sources, whether at home, in the office, or on the go.

• Industrial Equipment and Electronic Instruments: In industrial settings, various types of equipment and electronic instruments, such as test and measurement devices, control panels, and small - scale industrial machinery, may use the 5.5x2.5mm DC power jack. It provides a reliable and widely available power connection option for these devices, which often operate on low - voltage DC power.

Advantages

• Wide Compatibility: Due to its standardized size and electrical characteristics, the 5.5x2.5mm DC power jack offers excellent compatibility. Users can easily find replacement power adapters or connect different devices to a common power source, reducing the need for specialized or custom - made connectors.

• Reliable Connection: The cylindrical design and the snug fit between the plug and the jack ensure a stable and reliable electrical connection. This helps to minimize power interruptions and fluctuations, which is crucial for the proper operation of electronic devices.
