Extra DW10 Contact

I am using DW10s on several first floor windows. I’d like to be able to leave the windows partially open when the weather is good, but still be able to arm the alarm system and have it activate if someone were to open the window further.

Is it possible to order or obtain an extra sensor piece (the smaller piece, NOT the transmitter) instead of buying the full set? Seems like an added unnecessary expense.

You can buy the rare earth magnets just about anywhere.
