Constant advances achieving the highest
level of performance in its class
The FX-300 series of next-generation fiber sensors provides
the highest level of sensing performance in its class
‘Stable sensing’, ‘high sensing performance’, ‘easy operation’, ‘improved ease of
maintenance’ and ‘preservation of the environment’ are the five concepts underlying
the new FX-300 series!

In addition to a ‘four-chemical
emitting element’
which suppresses changes in the light emitting
element over time so that a stable level of light emission can be maintained over long periods, a
‘APC (Auto Power Control) circuit’ has also been adopted afreshly. The light emitting amount
can be controlled in minute degrees so that even changes occurring over very short periods
can be handled, allowing stable sensing performance by suppressing deviations in light emitting
amounts caused by changes in the ambient environment that could not previously be
suppressed.

Light emitting amount
Adoption of a ‘double
coupling lens’
that
increases emission efficiency to its
maximum limits and greatly increases
sensing range. Sensing ranges with small
diameter fibers and ultra-small diameter
fibers, which have become very popular due
to the miniaturization of chip components,
have been increased by 50 % over previous
values achieved with other amplifiers.

FX-301-HS
If the light receiving level becomes saturated during close-
range sensing or when sensing transparent or minute
objects, you can adjust the light emitting amount of the
sensor to stabilize sensing
without needing to change the
response time.
Sensing that previously required the response
time or fibers to be changed can now be set much more
easily using this function.
