Support for stable sensing and
smooth setup changes!
Teaching and data bank switching for up to a maximum of
16 digital fiber sensors (FX-301 and FX-305) can be
carried out all at once using an external device such as a
PLC, touch screen or switch.
Digital fiber settings can be changed using input from a touch screen or switch, so that
production line setup changes can be carried out more easily.

Explanation of limit teaching
The
operations are deter-
mined by S1 and S2,
and the input timing is
determined by S3.
The following types of external teaching can be carried out.
● Full-auto teaching ● Limit teaching ‘
● Limit teaching ‘
If the incident light intensity changes with
respect to the initial threshold setting value
because of reasons such as beam axis
slippage, sensing can become unstable
and incorrect operations can occur.
External teaching
Data bank switching
Full-auto teaching is recommended for teaching when the sensing object is changed
without stopping the line.
Settings such as output operations (L-ON / D-ON) and timer operations can be recorded
in the digital fiber sensor’s data bank and switching can be carried out externally.
m Up to 3 files can be stored.
