What do you mean with an "outdoor contact sensor"? The SNZB-04 is not technically rated for outdoor use. Are you weatherizing these somehow, or are they reasonably protected from the elements such that pretty much any sensor would work and you're just wondering about temperature?
Sensative Strips Guard is one I know of that is rated for outdoor use and also does temperature. I'm not sure what its minimum temperature readings are per spec, and I haven't had mine outside during winter yet to share personal experience. Most devices I've used outside don't give me funny readings until double-digits below zero Fahrenheit, though, aside from a driver/parsing issue I had with some device a while back (but it was still technically accurate enough when interpreted correctly). There are probably others.
I also know I've seen people weatherize "indoor" sensors with either silicone or by enclosing them in a weatherproof box. In my experience, the former makes battery changes hard (I did this with a cheap Sonoff motion sensor once), though this probably depends on the device and how careful you are. The latter probably will affect temperature readings (which I've also given up on with outdoor sensors in favor of a weather station, but most devices I used were still within a few degrees of that).
