Audio Connectors

Available in 2.5 mm and 3.5 mm audio standard versions, CUI’s line of audio jacks and plugs offer small package sizes with heights as low as 3 mm and widths as small as 5 mm, if you have requirement of 6.3 mm audio connector so please visit here . Offered in horizontal and vertical orientations, our audio connectors feature internal switches of 0, 1, 2, 3 and 4 as well as SPDT and DPDT options. Several models are also available with shielding and color insulator configurations of black, blue, green and pink. Thanks to their variety of mounting styles including cable, mid mount SMT, panel mount, surface mount and through hole, our audio connectors are the ideal solution to carry audio signals in a range of consumer electronics, home and office equipment, and portable electronic devices.

The RCA connector is used in several audio applications. S/PDIF (Sony ® /Philips Digital Interface) is the "red book" standard for digital audio signal transfer. A S/PDIF coaxial cable can carry linear PCM or multi-channel Dolby ® AC-3/DTS ® digital content. For dual channel stereo audio, two RCA connectors deliver the analog composite audio signal to the left and right channels of audio. In home theater, RCA is used as a powered subwoofer connection. In pro-audio applications, as part of an XLR to RCA cable, it can connect unbalanced sources to balanced XLR inputs for tape decks, CD/DVD players to mixing consoles and amplifiers, and can connect balanced line outputs from mixing consoles to unbalanced line inputs for recorders and amplifiers.

The 3.5 mm connector is commonly called a 1/8-inch connector or a mini-plug. This connector is a small, thin metal plug that can be used to carry one, two, or even three signals. The tip of the plug is separated from the sleeve of the connector by a concentric band of insulating material. For stereo or audio/video versions of the plug, there may be one or two additional metal bands, called rings, placed between the tip and the sleeve. 3.5mm connectors are commonly used for computers and portable devices for mono or stereo audio. A computer's sound card uses these connectors for speakers, line-in/line-out connections, and also for microphones. Portable devices use the 3.5mm interface as a line-out connection for headphones or for connection to an auxiliary input on an amplifier. The "three-pole" version of the 3.5mm plug is often used on camcorders. This plug has a tip and two rings, which can carry video as well as right/left stereo audio.

Audio encompasses a large number of interfaces including digital and analog. These are used in a number of applications from home theater and portable use to the pro audio mixing boards that DJ's and other audio professionals use. One similarity that most audio connector types share is they are easy to connect. Manufacturers of consumer electronics prefer to use simple interfaces that average users can connect and disconnect without having to tighten thumbscrews, or release tabs or latches. This preference can prove challenging to manufacturers who must balance convenience with performance.
