SJ-3555NG is a barrel-audio connector that primarily used to connect audio-visual equipment, such as microphones, audio processors, and speakers. A barrel-audio connector is an electrical connector that provides a secure connection between two pieces of audio equipment. It has a variety of shapes and sizes, but the most common type is a “barrel” shape and has multiple pins for different audio connections.

The SJ-3555NG has a male and female connector, and is a 7-pin connector used for connecting two pieces of audio equipment. It is commonly used for audio-visual equipment such as microphones, audio processors, and speakers. The 7-pin version is ideal for high-frequency audio equipment, as it provides additional support for the frequency range of the audio signal. The SJ-3555NG is a circular, 8-pin connector with a diameter of 4.2 mm. It is designed to provide low-voltage and low-frequency audio and video input and output for high-definition audio signals, and can support up to 7.1 channels of audio.

The connector is made of copper, gold, and nickel materials, which are known for their excellent electrical conductivity. The actual contacts are gold-plated copper, and the terminal block and female contacts are nickel-plated brass. The housing of the connector is made of ABS plastic, which is durable and resistant to corrosion.

The working principle of the SJ-3555NG is based on the four-wire connection. This works by connecting a two-pin and a four-pin plug together with two or more audio connections. The four wires are at the core of the four-wire connection and provide stability to the entire connection. The four-wire connection ensures that the signal is transferred accurately, ensuring that there is no interference or distortion in the audio signal.

The connector is designed to allow for quick and easy connection between audio sources such as a microphone, a processor, and an amplifier. The four-wire design and the gold conductors provide a strong connection, allowing for a secure and reliable electrical connection. The seven-pin connector also allows for flexibility when connecting audio systems, as it can be used for both stereo and surround sound systems.

The SJ-3555NG is suitable for a range of audio applications, including home theaters, recording studios, and other professional audio-visual projects. It is a cost-effective and reliable connector that allows for a secure and reliable connection between audio sources. Its gold conductors provide maximum performance and reliability, and its low-voltage and low-frequency design makes it an ideal solution for high-definition audio signals.
