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 40 mm from the laser-
emitting portion of the sensor head.
3. F.S. Stands for a measuring range of 20
mm.
4. The value when the object (white paper)
is measured distance of 40 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
