Snap and Lock DC Power Connectors
Snap and lock DC power connectors look similar to Mini-DIN connectors, but have either 3 or 4 thicker pins and a slightly larger mating shell. Because of this they do not mate with any of the standardized Mini-DIN connectors. They can usually be identified by an engraved symbol on the backs of the plug, consisting of two wide arrows pointing in opposite directions, but parallel to each other, or sometimes one wide arrow inside a box, pointing towards the end of the male connector. Some devices, however, use a true 4-pin Mini-DIN connector for power instead, presenting the possibility to mate such a connector with the wrong port (such as an S-Video output).
- Known as Kycon 3-pin and 4-pin DC power plugs.
- Erroneously also known as "Power DIN", although different from any standardized Mini-DIN or DIN connector type.
- The male plug's mating shell outer diameter is 10 mm (0.39 in), and the pins are 1.5 mm (0.059 in) diameter
- Standard may include a limit of 20 V at 7.5 amperes
