Phono (RCA) Connectors
Description | Applications | Pin Assignments | Assembly Instructions

Description
2-pole connector used for audio and video applications. They are designed such that the centre pin carrying the signal is enclosed by the outer ground connection to maintain the screening. Note that a phono connector only carries one audio channel - stereo applications use one connector for the left and one for the right channel. Also used in other applications.
Typical Applications
Hi-Fi - Interconnecting separates
Disco / Professional equipment - connections between equipment.
Composite and component video
Other miscellaneous applications
Pin Assignments
Connections for phono connectors in audio applications are:
Centre Pin: Signal (connect to insulated wire in audio cable)
Outer Shield: Ground (connect to screen in audio cable)
Note that other applications may use different connections.
Connector Assembly Instructions
Plugs and Line Sockets
Normally solder terminals. Remember to thread the cover onto the cable before soldering. Squeeze the cable clamp shut with pliers AFTER soldering, otherwise the heat will melt the insulation.
Panel Sockets:
Assemble to the panel, including the solder tag. Connect the screen to this tag, and the signal wire to the terminal on the back of the socket.
