Barrel – Audio Connectors are widely used in the music industry for connecting audio equipment. In this article, we will focus on the application field and working principle of the SJ-42516-SMT, a barrel connector manufactured by Amphenol, one of the world’s leading audio connector manufacturers.

Application Field

The SJ-42516-SMT is a rugged barrel-style connector, designed for connecting musical instruments, audio equipment, and other electric and electronic components. It is used in many different applications including professional audio, home theater, in-car audio systems, and DJ equipment.

Amphenol designed this connector to provide a reliable and secure connection to meet the demands of today’s audio enthusiasts. The SJ-42516-SMT has a standard 3.5mm diameter, making it compatible with most audio equipment, musical instruments and accessories.

This versatile connector also has a few special features that make it particularly suitable for certain applications. For example, the SJ-42516-SMT has two contacts, one for stereo audio and one for mono audio. This allows for better sound clarity and more flexibility when connecting different components. Additionally, the SJ-42516-SMT has an integrated strain relief structure that helps to reduce strain on connected wires and increase strain relief on soldered connections.

The SJ-42516-SMT is also very durable and is built to last in harsh environments. The connector is made of nickel-plated brass, which provides lasting corrosion resistance and extreme durability. Additionally, the connectors are equipped with a metal cap to help protect against dirt, dust and moisture.

Working Principle

When connecting two electric or electronic components, the connection process is always the same. Two electrical contacts, usually metal pins, are inserted into the connector and then a wire is connected to each contact.

In terms of electrical operation, the SJ-42516-SMT utilizes a single pole connection, which means the electrical current only flows in one direction. This is commonly referred to as a unidirectional connection and allows for more reliable and accurate signal transmission.

The contacts on the SJ-42516-SMT are also designed to provide a secure electrical connection by ensuring a tight fit between the pins and the connector. This helps to ensure that stray electrical noise does not interfere with the signal. Additionally, the contacts are gold-plated, which helps to increase their conductivity and maximize signal transfer.

The SJ-42516-SMT also features two channels for stereo and mono audio signals. The stereo connection has three contacts-the standard left and right and the third center contact is used for mono audio signals. This configuration allows for better sound clarity and more flexibility when connecting different components.

Conclusion

In conclusion, the SJ-42516-SMT is a versatile and reliable barrel-style connector from Amphenol, a world-leading audio connector manufacturer. Its single pole design and gold plated contacts make it an ideal choice for many different audio applications, including professional audio, home theater, in-car audio systems, and DJ equipment. Additionally, the integrated strain relief structure helps to increase strain relief and reduce strain on connected wires.
