Industry's First Power Tuning Function in a Digital Sensor.
No complicated mode settings.
Troublesome power adjustments have been eliminated, so it isn't necessary
to select from power mode settings, such as long-distance mode, standard
mode, and short-distance mode. When the MODE Key is pressed once, the
power tuning function shifts the power level so that the present incident level
is set to the ideal level (2000 on the digital display.)

The best mode for each application was
selected from several power modes.
The Sensor can be used immediately without
setting the mode.
If the incident light level is too high or too low,
just press the Mode key to achieve the optimum
status.
Insufficient light or saturation at short distances can be corrected.
The power tuning range is extended to the allowable limits to eliminate prob-
lems such as insufficient light or detection failures due to saturation.
If the installation distance is too short, the incident light may saturate (i.e., to
a digital incident level of 4,000), preventing detection. The power can be
tuned down to 1/25th of the default setting for stable detection even at close
range.

Variations between different Sensors can be eliminated.
Threshold levels had to be set and maintained separately for individual Sen-
sors due to variations in the digital light levels measured by each Sensor.
With power tuning, the incident level can be fine-tuned so the same thresh-
old level can be set for each Sensor in an application. Maintenance is also
simplified because it is easier to recognize measurement levels that have
shifted during operation.

Digital light levels vary due to individual
differences in the Sensors, so the
threshold levels must be set individually.

All of the Amplifiers are set to the same digi-
tal light level, so the same threshold level
can be set and maintained for the Sensors.
Large, Easy-to-Read Displays: Clear Even from a Distance
The displays are large and easy-to-read,
despite the small case.

Settings can be made more simply and confident-
ly with two digital displays. For example, the
threshold value can be changed while reading the
incident level or a setting can be changed while
confirming the setting's function item number.

Seven Convenient Display Formats
An incident level/threshold display, percentage/threshold display, and large bar graph display
have been added, so you can select the best display method for the application.

No incident light
Incident level Threshold level
Change the threshold level while read-
ing the incident level.
Incident level Threshold level
Verify the difference between the inci-
dent level and threshold level while set-
ting the threshold level.
Bar display
Check the incident level intuitively. Ideal
when it is better to view an analog dis-
play instead of the actual digital level.
Incident Level/Peak Hold Display
Incident level Peak hold
Simultaneously display the peak hold level and
present incident level. The optical axis can be
adjusted more easily and surely by checking the
peak hold level while adjusting the optical axis.

Display the peak level when light was brightest and bottom level when light was
dimmest. The digital levels of high-speed objects can be read precisely.
(Refreshing the hold level was changed from a fixed time to synchronizing with
the output, so the peak and bottom hold values can be checked with certainty.)
