MICRO-PLUG® Series, Audio Connectors

Audio Connectors refer to a specific type of barrel connector designed for audio applications. These connectors are commonly used to establish electrical connections in audio equipment such as headphones, microphones, musical instruments, amplifiers, and audio interfaces. Characterized by their cylindrical shape, audio barrel connectors typically consist of a plug divided into multiple sections along its length. One end of the plug is often designed with an indented region that engages with a spring-loaded contact in the mating jack, providing mechanical retention to ensure a secure connection. The most prevalent nominal sizes for audio barrel connectors include the 1/8" (3.5 mm) format and the 1/4" (6.35 mm) format. The 1/8" connectors are widely utilized in desktop and mobile devices for audio connections, such as connecting headphones to smartphones or laptops, due to their compact size and versatility. On the other hand, the 1/4" connectors, although larger, are commonly found on older or non-portable audio equipment, offering increased durability and robustness for applications where sturdiness is prioritized over compactness. In summary, audio barrel connectors are a specialized subset of barrel connectors tailored specifically for audio applications. They provide reliable electrical connections for a range of audio devices and equipment, offering options for both compactness and durability based on specific application requirements.
