That looks to be an IEC C13 cable, the same ones that are typically used in laptop or desktop power supplies.
Heads up before modifying anything that will interface with this cable or the cable itself - it transports mains power which is lethal, definitely contact a licensed electrician to do any work on it.
At first glance, I thought that was an IEC C13 cable myself but the bottom pin is not quite right. I think it might be a C21 cable though we don’t stock those. IEC 60320 - Wikipedia
That is not IEC C13. The “earth” pin is the wrong orientation. IEC is “vertical” the same as the others.
That socket is clearly marked “DC 100V 15A + and -” so it is definitely meant to be a polarised DC connector.
You may have to browse Element 14 or RS. Using filters will narrow the search somewhat. I can’t place it off the top of my head.
Thanks Liam. It’s not that plug unfortunately. The Top pin is vertical
Hi Trent. Thanks but the pin orientation is all vertical on c21
Thanks Bob will try
