2 types of received
light level indication
Level indication mode
The level of received light is indicated in 4-digit number.
Position on the electronic
volume: 8
The sensitivity position on the electronic volume
and the current received light level are displayed.
There may be an error of ± 1-2 between the value on
the LCD and the actual value.
Enhanced teaching features
(sensitivity setting)
Full auto teaching
●
Simply pressing the button allows easy teaching; even
for an object moving at a high speed.
Auto teaching
●
2-point teaching "with" and "without" the work allows the
detection of slight level difference such as the thickness
of a piece of work and the presence of a film.
Position teaching
●
This feature is ideal for high-accuracy positioning that
requires accurate determination of a detecting point.
Maximum sensitivity setting
●
For applications requiring maximum sensitivity setting
such as the detection of work with a through-beam type
fiber optic cable, the extra-powerful light allows for use
in an adverse environment.
Manual setting
●
Arbitrary manual increase and decrease of a "set-point"
allows level setting while checking the operation.
Min. = 0 / Max. = 1023
Displacement indication mode
The example above shows that the current receive light
level is -123 with reference to the activation level.
The level of received light is indicated in positive or
negative value with reference to the activation level.
The activation level is taken as the reference (± 0) and the level
of received light with work used is indicated as a deviation from
the reference in a positive or negative value.
Secure detection of an instantaneous signal
is ensured with the off-delay timer

A small object moving at a high speed can be
securely detected, thus allowing for a wider range
of input conditions for the connected devices.
