ANALOG OUTPUT TYPE
OPTICAL FIBER
PHOTOELECTRIC
SENSOR UZF36
NEW ANALOG OUTPUT TYPE FOR DIVERSE APPLICATIONS
Analog V oltage Output
Incorporated with the analog voltage
output (1 to 5V).
Various Uses
The analog process with various kinds
of fiber heads offers unique application
solutions such as a height evaluation,
or a gap detection.
Automatic Crosstalk
Prevention Function
Two sets of fibers can be mounted
close together or face to face.
Saturation Indicator
Saturation indicator lights up when the
output reaches 5V, thereby its sensitivi-
ty is easily adjusted without using a
tester.
The incident beam indicator brightens
up in proportion to the amount of inci-
dent beam (output voltage).
Slim
Space-effective as it is only 10mm
.394inch thick.

APPLICATIONS
Comparing traveling objects in
height
With the array fiber, columns are classi-
fied in height.
Detecting gap to boards
No sensitivity setting is required even
as products are changed over because
of the differential sensing.
Detecting irrelevant products
Extraneous products are sorted out that
differ from normal products in reflection
ratio.
Ascertaining the number of translu-
cent films
The number of translucent films over-
laid is inspected by beam penetration.
Sensing turbidity of liquid
The turbidness of liquid inside a clear-
wall tank is analogically observed.
Measuring inner diameter of rings
Rings are classified according to inner
diameter.

PRECAUTIONS FOR PROPER USE
Amplifier
Mounting
1Hook the rear part to the
attached mounting bracket
(UZF811) or DIN rail.
2Press the amplifier down on
the bracket or DIN rail.
How to mount the amplifier
1Push the amplifier frontward.
2With keeping on it, lift up the
front part of the amplifier.
How to remove the amplifier
1Unlock the fiber lock
lever upright.
2Insert fiber cables
into the inlets slowly
until fully deepened.
3Lock the fiber lock
lever on the original
position.
How to connect fiber cables
(*1) : With the coaxial diffuse fiber such as the UZFRG4 or the UZFRF8, insert
the mono-core fiber cable into the beam-emitting inlet and the multi-core
fiber cable into the beam-receiving inlet. If they are inserted in opposition,
the repeatability will deteriorate.
Crosstalk prevention function
• Two sets of fibers can be mounted close together that con-
nected to the UZF36 amplifiers because of the crosstalk
prevention function.
Two sets of the UZF36 amplifiers should be set the wiring
and switches on them as follows.
1) Wiring
• Connect both crosstalk prevention wires together under
both 0V wires in common.
2) Crosstalk prevention selection switch
• Set the crosstalk prevention selection switch on “MAIN” for
the first amplifier and on “SUB” for the second amplifier.
∗To neglect crosstalk prevention function
• If the amplifier is used singly, set the crosstalk prevention
selection switch on “MAIN”, otherwise it is not operable.
• Insulate the crosstalk prevention wire.

PRECAUTIONS FOR PROPER USE
Amplifier
Response time selection
• The response time of the UZF36 can be selected either
“1ms” or “10ms”. If your detecting application does not need
the quick response, “10ms” is recommended as it makes the
detection secure against inductive noises and ambient
lights.
If you choose “1ms”, pay attention to inductive noises and
ambient lights.
• The response time stands for the processing time that the
output follows to an input change, either from the complete
Dark level (1V) up to 90% extent of a certain Light level or
from the Light level down to the complete Dark level 10%
extent beforehand. The response time of the UZF36 is con-
stant regardless of the amplitude of the output voltage. The
usage with “10ms” is recommended to gain the output relia-
bility if you do not require quick response. When you select
“1ms”, carefully consider the influence of extraneous lights
or inductive noises.
Sensitivity adjustment
Others
• The transient time duration is 50ms after power-up.
