Most deltas have some amount of effector tilt as the head moves around the print surface, so a Z sensor that is offset from the nozzle will introduce errors due to tilt.
This sensor has zero X and Y offset, which means that effector tilt doesn't affect the measured Z value.
It automatically deploys and retracts, and seems to work very well.
