RCA (Radio Corporation of America) connectors, also called phono connectors, jack connectors, or Cinch connectors, are a type of electrical connector designed to transmit audio and video signals in multiple audio/video equipment. The RCA originally developed these connectors for consumer electronics and professional audio/video equipment. RCA phono connectors are characterized by their distinctive design that comprises colour-coded plugs (male and female) with a central pin surrounded by a metal ring or shield. An RCA cable features two or three plugs for audio, video, and S/PDIF (Sony/Philips Digital Interface) signals. These cinch-type connectors are widely used in a range of A/V equipment or applications requiring shorter lengths, as they are susceptible to EMI.
For What Purpose Can I Use an RCA Connector?
An RCA connector uses RCA cables to transmit various signal types, including digital, analogue, component, and composite analogue audio. Furthermore, RCA connectors come in cable mount, chassis mount, panel mount, PCB mount, and snap-in mounting configurations and voltage ratings, meeting different requirements for your audio and video applications.
Colour Coding of RCA Connectors
To help users identify different signal types, RCA connectors are often colour-coded. They may also come in colour combinations where the most common colour codes with their representations include:
- Red (right audio channel)
- White/Black (left audio/stereo channel)
- Yellow (composite video)
- Red, Green, Blue (component analogue video).
Popular Types of RCA Connectors
Radio Corporation of America connectors come in various types and configurations to suit different needs. Some of the most common RCA connector types include:
- Male RCA Connectors – Male RCA connectors have a central pin surrounded by a metal barrel. They are typically used as the output connectors on devices like DVD players, CD players, and audio receivers. The central pin carries the signal, while the barrel is the ground connection.
- Female RCA Connectors – Female RCA connectors have a central hole that accepts the male RCA connector's central pin. They are typically input connectors on devices like televisions, speakers, and amplifiers. The male RCA connector is inserted into the female RCA connector to establish a connection.
- Audio RCA Connectors – These are the standard RCA connectors for transmitting analogue audio signals. They typically come in pairs (red and white) for stereo audio, with the red connector representing the right channel and the white connector representing the left channel.
- Right-Angle RCA Connectors – Right-angle RCA connectors have a 90-degree bend in the connector. This design allows for easier cable routing in tight spaces or when connecting devices close to a wall or other obstacles.
- Straight RCA Connectors – Straight RCA connectors have a straight, linear design without bends. They are the most common RCA connectors used in a great range of audio and video applications.
Typical Applications of RCA Connectors
RCA connectors are explicitly designed to connect audio/video equipment and everyday devices, including:
- TVs
- DVD Players
- Gaming Consoles
- VCRs
- Home Theatre Systems
- Speakers
- Cable Boxes.
