Up-to-date Image Processing Technologies.
Z300
Features
Stable measurement of a transparent object or a glass.
A wide variety of sensor heads for enhanced detection possibilities.
OMRON's Z300 makes the notion that displacement sensors cannot perform stable measurement of a transparent object
or a glass a thing of the past. The newly-developed 2-dimensional CCD (S-CCD) incorporated in the Z300, combined with
upgraded performance of the controller, provides enhanced stability and accuracy in measurement of a transparent object.
The latest algorithm employed by the Z300 enables optimal sensitivity even if there is a big difference between the amount
of reflected light from the surface and that from the bottom of a glass.
Enhanced measurement area and a variety of high-resolution,
long-distance sensor heads greatly expand the range of
applications.
The Z300 is just another example of OMRON's ongoing
challenge to the limits of sensing possibilities.

The innovative 2-dimensional CCD (S-CCD) is the key to the sensing performance.
The 2-dimensional CCD enables stable, high-speed
measurement.
A conventional displacement sensor using a 1-dimensional
CCD cannot deal with flutter influence to the output. Therefore, the sensor requires increased number of measurements
for signal averaging, which leads to slow response time. The
S-CCD with a 2-dimensional CCD has solved this disadvantage, by splitting the measurement point into 60 lines for measurement in finer detail. The value per each pixel is then
averaged to produce a reliable output, free from flutter influence caused by the object's surface condition. Stable detection and high-speed processing is thus possible with the Z300.
CCD makes a difference in measurement of a
transparent object.
PSD sensor
A PSD sensor using diffuse reflection is virtually
prevented from performing measurement due to
insufficient reflection distribution from the surface.

reflection method, on the
other hand, receives reflective light from the bottom or background of the
object, which causes an
error in determining the
target position, impeding
accurate measurement.
CCD sensor
A CCD using the mirror reflection method is a solution. It can extract only the
light reflected off the surface of the target. Accu-

Monitoring as the object is being measured.
Measurement data can be recorded and played back.
Easy-to-see color display is another great feature of the Z300 (when connected to a color monitor). Monitoring at each key stage
including test and adjustment, operation, or maintenance greatly facilitates efficient, error-free measurement.

The measured value is displayed. The use of two
colors: green for "Pass" judgement, and red for
"High/Low," enhances visual recognition of the
measurement result.
Displays the position of measurement point as well as
intensity of the reflected light.
Conveniently checks whether optimum measurement
is taking place.
Monitoring during recording and playback
Test mode Conditions during Test mode can be
recorded and played back
Any desired number of measurement data can be
stored for testing with a workpiece.
Test measurement data obtained off-line can be
saved for reference for actual in-line measurement.
Continuous measurement values during a certain
period of time are shown in chronological order.
Changes in the measured values of a moving or
rotating object can be checked at a glance.
NG (High/Low) judgement status is
recorded and played back.
Up to 20 in-line NG data (information including
reflected light condition and measurement data) can
be recorded for workpiece analysis as well as for
troubleshooting.
