All threesizes are now readily available in two-conductor (mono) and three-conductor (stereo or tip ring sleeve) versions.
Both two-conductor and three-conductor versions of the three standard sizes are readily available in male (plug) and female (socket or simply "jack") line versions, and panel-mounting female versions.
Non-standard sizes, both diameters and lengths, are also available from some manufacturers, and are used when it is desired to restrict the availability of matching connectors.
