Connecting the Sensor Head and the Amplifier Unit
■ How to connect the amplifier unit and the connector
1
Open the dust cover, and tilt the
hold-lock lever.
2
Raise the hook, and insert the
connector to the very end.
3
Lower the hook and
hook the part shown
in the figure, and
then raise the hold-

Note
When shortening the sensor head cable, follow the instructions given in the
“Sensor Head Connector Assembly Procedures” included with the sensor
head.
Mounting and Adjusting the Sensor Head
LV-S31
■ Adjusting the trimmer (detection position)
The detection range can be selected as desired by adjusting the trimmer.
■ Adjusting the center of detection
1
Place the workpiece at the position you
want to set as the center of detection.
2
Turn the trimmer until JUST
indicator (2) illuminates in green.
Finer adjustment is possible by looking at the display on the amplifier (page 9).
■ Detecting a height difference
A stable detection is made possible by
adjusting the trimmer so that the middle
point of the height comes to the center of
detection.
■ Movement directions of the workpiece
LV-S41/S41L
Be sure to use the supplied mounting bracket.
1
Press the mounting bracket on the sensor head.
Be sure to hook the A portion of the mounting bracket on the B portion of
the sensor head.
2
Install the sensor head on the flat surface with the
M3 screws as shown in the following figure.
(The M3 screw is not an accessory.)
LV-S62
Mount the sensor head using either L-shaped mounting bracket (OP-84350),
rear mounting bracket (OP-84349), side mounting bracket (OP-84351) sold
separately.

2
Insert the protrusion on the amplifier for
securing the bracket into the hole at the
upper part of the bracket.

• Adjusting the beam axis
(1) The beam axis angle can be adjusted horizontally by swinging the
bracket to the left and right with screws (a), (b) and (c) loosened. In order
to tighten the screws, be sure to tighten screw (b) first.
(2) The angle of the beam axis can be changed downward if the screw indi-
cated by the arrow is tightened, and upward if loosened.
When detecting the target
from a long distance, turn the
trimmer clockwise to adjust. When detecting the target
from a short distance, turn the
trimmer counterclockwise to
adjust.
