After trawling eBay looking at everything, I have found this model.

Search for item number 292899407437 and it takes you to a listing with lots of components and in there you can select this item.

Anyone heard of it?

-----------

I have now found it on AliExpress and it seems to take a 3 volt button battery!

It is one of their newer modules. Tazzy

I had not really thought of the size, but after hunting I have found it is the same width and depth as the SO25, just half the height of it.

I'm just deciding what items we are going to install, so I will grab one of these and see what it is like.

Now that I have received both sensors, side by side I think the new model looks neater.
The coin is a British one pound, similar in size to a Euro or US quarter.

Need to now get the K7 system I ordered to realise that this sensor should know it is open when the system is being armed!
