EX-F1
This product is not a safety sensor. Its use is not
intended or designed to protect life and prevent body
injury or property damage from dangerous parts of
machinery. It is a normal object detection sensor.
Selecting output operation
• Either Light-ON (Liquid-
absent-ON) or Dark-ON
(Liquid-present-ON) can be
selected with the operation
mode switch according to
your application.
Mounting
• Mount the sensor on a pipe with the attached tying bands
and anti-slip tubes as shown in the figure below. Make
sure that the release lever is retracted (position as in the
figure) before mounting.
Fasten two tying bands, as shown, and cut off the excess
portions.

Position adjustment
•
After it is mounted on the pipe with tying bands, the
sensor position can be easily adjusted.
Adjustment
1
Unlock the release lever (in the
direction of the arrow).

3
Lock the release lever to its
original place.
2
Press the movable center hold-
ers forward to loosen the tying
bands and adjust the position.

Note: The lever mechanism must be used only to adjust the position, and
not for tightening the tying bands. If tying bands are tightened while
the lever is open, and then the lever is locked, the sensor may be
damaged.

Others
•
Do not use during the initial transient time (50 ms) after the
power supply is switched on.
•
Do not use this sensor with a pipe which is not transparent.
• Unclear or highly viscous liquid may not be detected.
• Fit the sensor to the pipe securely, otherwise the operation
may be erroneous.
•
Take care that no dew condenses
on the pipe’s sensing surface or the
pipe’s inside wall and that no bubble
attaches on the pipe’s inside wall,
since it can affect the operation.
•
If a liquid drop flows down across
the sensing point or an air bubble
sticks on the wall at the sensing point, the operation may be
erroneous. Make sure that no bubble arises in the liquid, and that
no dew or liquid drop is present on either surface of the pipe wall.
• EX-F1 is not water-proof or chemical-resistant. Installation
should be avoided at any place where it could come in
direct contact with water or chemicals.
