Features

The entire series of connectors has a built-in retention feature. On types 1, 2, and 3 this involves a bevel on the barrel near the tip, while on types 4 and 5 the tip of the insulator ring has a larger diameter than the metal barrel.

Types

The design philosophy is that higher voltages should be supplied via larger plugs to prevent equipment damage. A larger plug will not go into a smaller jack.

ET-2502A

The use of these connectors on equipment is defined in JEITA ET-2502A. For instance, this document describes the interface between a car cigarette plug or RC-5321 plug and the powered device, the polarity symbol used (JEITA CP-1104A),

EIAJ RC-5321

This is a unique-looking barrel connector, apparently intended for providing a DC ''output'' jack (most DC jacks are used for power input). Possibly available in multiple voltage ranges, the one for voltage classification 2 (3.15 to 6.3 V) has an outside diameter of 4.75 mm and a protruding pin of 2.5 mm diameter.
