1. An elevator door sensor arrangement including:
a position sensor configured to determine a configuration of an elevator door of an elevator car;
an auxiliary sensor mounted to an elevator header of the elevator car or within the confines of the elevator car and configured to monitor for an object in a sensing region outside of the elevator car, the region being an approach to the elevator car; and
a door sensor controller configured to output a signal to a door controller indicating that an object has been sensed by the auxiliary sensor in the sensing region approaching the elevator door, wherein a depth of the sensing region extending into the approach to the elevator car is altered based on the configuration of the elevator door as determined by the position sensor.
