Offset mounting of z-wave contact sensor

I’m installing a z-wave contact sensor on a door. There’s not a wide enough area to mount the smaller part on the same “plane” on the trim around the door opening as there is on the door. I can mount it about a half inch higher on the moulding but it would be about a half inch out from the main part of the sensor. The instructions say it should be within an inch of the main part. Would it work mounted this way? Don’t want to attach them and try to remove and reattach them.
