When the wire is permanently attached to the sensor, it's not reasonable to require it to be changed.

Our 2009 robot design had a 5A fuse inline with the 12V power to the Banner sensor for exactly the reason the KC inspector gave. (There was a brief moment of contention when one of the inspectors at DC didn't think such fuses were legal, but he was of course unable to come up with any support for that opinion in either the manual or the inspectors' checklist.)
