I would like to select a single motion detector to drive lighting in a 70 foot hallway (straight corridor approximately 6 ft wide). A 70 by 6 foot rectangle is to be covered. If it is necessary to use more than one detector then so be it, however less is more.
What are the specifications of a motion detector that describes it range in the above context?
The current switch is a mechanical timer with maximum of 20 minutes. A traditional switch, which can be left on indefinitely is not acceptable in this particular scenario. The switch should stay engage lighting for 10-20 minutes.

If you are able to wire in a device at a height of 7' on one end of the hallway, you can use this Lithonia Acuity HW13 Hallway Sensor that will give you a straight line range of up to 130 feet.
When choosing a motion sensor, I usually take into consideration the motion angle and the square footage of the detector. We use 180 degree detectors in our hallways.
Here is a diagram of motion light switch that covers 180 degrees at up to 900 sq. feet. It would cover appx. 16.9 feet in either direction and up to 16.9 feet in front of it with an overall square footage of 900 square feet.
