The emitted light and output indicator flash

at the same frequency.

Attenuation function [SET mode]

If the light receiving level becomes saturated when

sensing over short distances or when sensing

transparent objects or minute objects, the light emitting

amount can be reduced so that stable sensing can be

provided without needing to change the response time.

Teaching using ON / OFF buttons [SET mode]

Simply press the ON button when an object is present

and OFF when it is not. There is no need to switch

settings or make judgments between Light-ON (

)

and Dark-ON (

).

Interference prevention function [SET mode]

The emission frequencies can be set separately for

each unit in order to avoid interference. The emitted light

flashes while setting is in progress, so that you can see

at a glance which fiber sensor is currently being set.

In addition, this interference prevention is not done by

using optical communication. This means that there is no

need to place the amplifiers close together like there was

before, and so the amplifiers can be set up apart from

each other.

FX-101□: Interference prevention for up to 3 units

FX-102□: Interference prevention for up to 4 units

Multi-function external input [PRO mode]

Settings such as emission

halt, limit / auto teaching

and ECO settings can be

carried out via external

input.

Alert function [PRO mode]

When the amount light received approaches the

threshold value, the display can be made to blink in

order to alert the operator.

* When the emission frequencies are changed, the response times will

also change.

Limit teaching function

This carries out teaching and sets threshold values only

when no object is present (when the incident light amount

is stable). This is useful when sensing objects if there

are other objects in the background and when sensing

minute objects. Teaching can also be carried out using

external input.

Threshold tracking function [PRO mode]

This function seeks changes

in the light emitting amount

resulting from changes in

the environment over long

periods (such as dust levels),

so that the incident light

intensity can be checked

at desired intervals and the

threshold values can be reset

automatically.

GETA function [PRO mode]

The display value for the incident light intensity can be offset

by the desired value (target value). The target value can be set

to between 0 and 2,000 (in increments of 100). For example, if

the incident light intensity is 1,500 and the target value is set to

2,000, then “2,000” will appear in the digital display.

Unify at 500 using

the GETA function

Variations in the amount of light received

<When using at a shift amount of 20% and a threshold value of 1,000>

The amount of light received ranges from about 900 to 1,100

when the digital indicator flashes.
