1. Distance from the surface of the laser-
emitting portion of the sensor head.
2. The beam spot is visible when the object
(white paper) is placed at a distance of
100 mm from the laser-emitting portion
of the sensor head.
3. F.S. stands for a measuring range of 80
mm.
4. The value when the object (white paper)
is measured distance of 100 mm from
the laser-emitting portion of the sensor
head.
5. The range can be expanded to “-5 V to
+5 V” by using the 0-ADJ and SPAN
adjuster trimmers. The alarm output is
approx. 7 V.
6. Incandescent lamp or fluorescent lamp
