Yes, totally normal. I would add that the sensor should go in the angled valve hole at the edge of the wheel. If it is mounted to the hole that goes straight down into the barrel of the wheel, it will be nearly impossible to mount a tire without breaking the sensor. The body of the sensor should be pretty flat against the wheel when installed.
