digital fiber sensor FX-301/FX-301P/FX-301B/FX-301BP/FX-301G/FX301GP

light-emitting amount selection FX-301  FX-301-HS  FX-305

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.

large display 9999   fx-305

Large display with 4 digits (9999). With a greater
difference in digit value than previous models, threshold
values can be set in units of 1 digit up to maximum 9999.
Threshold setting can now be done more easily and
accurately.

Ultra high-speed 35 μs response  FX-301-HS

Ultra high-speed 35 μs response. Even small objects
moving at high speeds can be sensed. In addition, at 65
μs the FX-301 standard
type and FX-305 highfunction
type is also
twice as fast as previous
models.

Simplified systems using new operating modes

A window comparator mode and
differential sensing mode have
been added. These modes make
it easy to carry out sensing tasks
that previously required multiple
sensors or involved complex
threshold settings.

equipped with 5 types timers

The FX-305 includes the same ON-delay / OFF-delay / ONE SHOT timer
as the FX-301(-HS), as well as an ON-delay • OFF-delay timer and an
ON-delay • ONE SHOT timer. A wide variety of timer control operations
can be carried out by these fiber sensors alone.
