PowerG PG9303 Magnet Dimensions

Can anyone tell me the exact dimensions of the magnet casing that comes with the PG9303? I’m planning my first alarm system with an IQ Panel 2+. I would like to go with the PowerG sensors if possible, but the magnet looks a bit larger than other sensors and I barely have 1/4" of depth to work with on the top window of my double hung windows. I want to mount these where the top and bottom windows meet along the lock so I can avoid having to double up on contact sensors.

Those magnets are closer to 1/2 inch wide and 3/8 inch deep.

The smallest sensor magnets I am aware of, and the only ones that I have seen to ever really work consistently with double hung windows like how you are describing are those that come with the RE122 Nanomax sensor
