Standard target: A standard target is square, 1 mm thick, and made from type FE360 carbon
steel. The length of the side of the square is equal to the diameter of the sensor’s active
surface, or three times the rated operating distance, whichever is greater.
Turn-on time is the elapsed time from when the target enters the sensing range until the
output switches.
Turn-off time is the elapsed time from when the target is removed until the output switches.
