I have a 12v 6.67A power supply with a male co-axial plug (with centre pin) that's 7.4mm OD and 5.08mm ID. The metal tube is 12.5mm long.
The pin is recessed and about 1mm in diameter - which seems impossibly small for 6.67A.
A chassis mount socket that would take it would come in handy. But I don't seem to be able to find one. Am I just using the wrong search terms?
Any pointers much appreciated.
On a KISS basis - I tend to just use a bimetallic switch or omit the temperature control and just run the fan from power up. It's possible for a processor to suffer some non-handled exception where it no longer executes the temperature management routine.
