Optex VX-402 - Settings and Adjustments; Detection Length Adjustment

6-1.Detection Length Adjustment
Length of Lower Detecion Area decides
detection length
The upper detection area stays parallel to the
ground at all time. The lower detection area
moves as shown above depending on the switch
position. So, length of the detection is limited by
the length of lower detection area, since both
upper & lower detection area have to be blocked
at the same time to activate the sensor.
