The Proler 2 is a high-precision prole measurement sensor.
The characteristics of this product are shown below.
• This product achieves high-precision measurement by emitting a bandshaped laser beam and using a light-plane-intersecting method that
triangulates the reected light.
• Settings can be congured, measurements can be performed,
and output can be generated from the sensor. No amplier unit
or other auxiliary devices are necessary.
• Various settings can be set from the sensor or from the dedicated setup
software (PRO2-navigator).
• It is possible to measure 4 areas with a single measurement. For each
area, there are 13 types of measurement functions to select from.
• There are 4 camera modes available. This enables you to select
the optimum settings to match the environment of the production line
to be measured and the state of the target object.
With the light-plane-intersecting method, the reected light from the
emitted band-shaped laser beam is received by the light receiving element
(CMOS), and the prole is then measured from the resulting image data.
With the light-plane-intersecting method, two processes are used to
determine the height and position.
• Triangulation: To determine the height, this process obtains the received
light waveform (the waveform of the reected light) for each vertical line
of the image.
• Projection transformation: To determine the horizontal position,
this process mathematically calculates the actual position from
the image data.

Stray light
Laser exposure
direction
The Proler 2 performs measurements by emitting a parallel laser
beam and receiving the reected
light.
During measurement, ensure that
the laser beam and reected light
is not blocked by the target object.
Before using the product, check
that stray light, which is reected
by a wall or by highly reective
objects, does not have an eect
on the measurements.
1. Insert the included mounting screws (two M4 × 50 mm screws)
into the mounting holes to temporarily ax the sensor to a location
that is roughly in the desired location.
2. Measure the distance between the sensor and the detection
target object. Please make sure the measuring object is within the
measuring area.
3. Adjust the sensor position on the basis of the measurement result,
and then use the included nuts and washers to x the screws in place.
You can take basic measurements simply by setting the following three
items. Congure the settings from the sensor or from the PRO2-Navigator
setup software.
• Shutter time
• Area
• Output conditions
Reference: For the actual screens and for information on the operations,
see the following pages.
Conguring settings from the sensor
Using PRO2-Navigator
1. Set the shutter timePosition the measurement target, and then perform automatic adjustment.
The optimum shutter time will be set.
→ “6.3 PRO2-Navigator Screen and Operating.”
→ “5.3 Setting.”
2. Set the areaUse the area setting to specify what part you will measure and how that
part will be measured.
1. Measurement area
• Set what part within the measurement range will be measured.
The set area must intersect the prole (the sectional waveform).
2. Measurement function
• Set the measurement function. You can select from functions
such as height and width.
Reference: For details on the area settings, see “7.6 Area Settings.”
3. Set the output conditionsCongure the settings related to the output of the measured results.
First, specify the judgment and output target area.
• Output target
Select the target area (area 1 to area 4 and calculation 1 and
calculation 2).
1. Measurement output
The product judges whether the measurement is a pass or a fail,
and then outputs the result.
• Upper limit/lower limit
2. Analog current output (4 to 20 mA)
• 4 mA/20 mA
Set the lower and upper limits of the analog output range.
When you have nished conguring settings or when you are not sure what
menu you are currently on, you can follow the procedures below to return
to the main menu (the measurement screen).

7.4 Camera Settings
7.4.1 Camera Mode
Select the camera mode. For “Hi-res” mode and “Hi-spd” mode,
one measurement is performed for each image.
For “HDR” mode and “NR” mode, two images are taken by the camera
for each trigger, and then one measurement is performed for these
two images.
Tips:• After the camera mode is changed, measurements are not performed
for the rst two triggers.
Camera mode: “Hi-res”All pixels will be used by the camera to take a high resolution image.
Normally use this mode.
Camera mode: “Hi-spd”Pixels will be averaged in sets of four. Image capture time will be 1/4
but resolution will be half in both the horizontal and vertical directions.
Figure: Dierence in resolution attributable to the camera mode (example)
Camera mode: “HDR”In “HDR” (High Dynamic Range) mode, screens captured by the camera
at two dierent shutter speeds are combined. This makes it possible
to perform stable measurements of parts that are highly reective or that
are minimally reective.
Use this mode when you cannot capture images with a single shutter
speed such as for metallic surfaces on circuit boards, very uneven
surfaces, or when the surface exhibits large color or prole dierences.
Tips:• Because two images are taken for each measurement, this mode has
a long sampling period.
• When measuring workpieces that move at a high speed, the HDR image
combination may not be perform appropriately.
Use this mode when measuring workpieces that have parts whose reective
status vary greatly. The following example uses a workpiece that has a
white and a black part, as shown in the gure to the right.
To measure this workpiece, it is necessary to acquire a prole like that
shown below.
Image example Prole example
In “Hi-res” mode, if the shutter speed is increased (made shorter),
the reected light from the black part is insucient to perform the measurement. If the shutter speed is decreased (made longer), the reected
light from the white part is saturated, leading to poor precision.
In “HDR” mode, the brightness from images captured at fast shutter
speeds is amplied. The amplication rate is determined by the ratio of the
shutter speeds of the two images.
(Example: If the shutter speeds are 1000 μs and 4000 μs, the amplication
rate will be 4000/1000 = ×4.)
During amplication, areas where the light level is low will be eliminated in
advance as noise. (The part marked with the “X” in the following gure.)
Adding the two images together makes it possible to measure any part
of the resultant image with the appropriate amount of light.
Functions
Mandatory settings when using HDR
HDR shutterIn addition to the normal shutter, set the speed of the shutter that will be
used to take the image with the slow shutter time.
This must be set to a value that is longer than the normal shutter speed.
When you select “HDR” mode, this is automatically set to a value that is
four times the shutter time.
Camera mode: “NR”In “NR” (Noise Reduction) camera mode, two images are taken: one when
the laser is on and one when the laser is o. Measurement is performed
on the dierence of these two images.
Because the image taken when the laser is o can be canceled, this function
is eective in situations where light other than that from the laser — such
as noise — has an eect on the measurement. Also, the noise generated
during imaging with a high gain can also be canceled.
Use shutter time and gain to adjust the camera screen brightness.
With “Auto adjust”, the shutter speed will be adjusted to the optimum value.
ShutterSet the camera shutter time. Set this value in steps of 5 μs.
The longer the shutter time, the brighter the images that can be taken.
However, the images may be blurred for workpieces moving at high speeds.
GainSet the camera gain.
The larger the value, the higher the gain, which makes it possible to
perform measurements even with small amounts of reected light.
If you increase the gain too much, there will be lots of noise, which may
lead to unstable measurements.
Auto adjustOptimize capturing condition automatically that matches with currently set
work piece.
Set the work piece to measure at the adequate position and execute “Auto
adjust”.
Don’t move the work piece while “Auto adjust” is proceeded.
When external trigger is used, check the prole is captured as you expected
for around 20 to 50 times, depends on the condition, to make sure.
Tips: • "Hi-res" and "NR-Mode", “Gain”, “shutter time”, “Threshold” and “Reject
Level” will be adjusted automatically by pressing “Auto adjust” button.”
• When you do not use automatic adjustment, set the shutter speed and
the gain, and then adjust these settings so that the appropriate received
light waveform is generated. If the amount of light is insucient
(the center waveform) or is too large (the lower-right waveform), it will be
dicult to perform accurate measurements. Adjust the shutter speed
and the gain until the received light waveform becomes like the one
shown below in the lower-left.
Appropriate shutter speed Insucient amount of light Too large amount of light
→ Make the shutter time longer. → Make the shutter time shorter.
Set the camera Range.
The narrower you set the camera range, the shorter the imaging time and
the sampling period become.
The default value is the entire camera range. (Sampling period: 5 ms)
Purpose of narrowing the
camera range
(a) Shortening of the
measurement time
(b) Noise preventionDepending on the workpiece prole and the environment, measurements
Narrowing the camera range has advantages such as those shown below.
When you narrow the camera range, the sampling period will be shortened
by a corresponding amount.
This makes it possible to perform measurements on production lines that
move at faster speeds.
may be unstable due to the presence of noise and diuse-reected light.
Setting the camera area just to the measurement range can prevent the
inuence of these elements on the measured results.
Diuse-reected light
Figure: Example of noise prevention implemented by narrowing the camera area
The heights of all the parts where the laser strikes the target are measured
from the waveform. The waveform is a vertical graph of the reected light
of the laser.
The following two settings are related to the recognition of the received
light waveform. Normally you do not have to change these settings.
ThresholdIf the amount of light of a part of the received light waveform is less than
or equal to this setting value, that part of the waveform triggers alarm (no
measured value).
The unit is the received light amount (in 256 levels).
If you specify a value that is too high, the number of areas where
measurement is not possible will increase.
If you specify a value that is too low, noise components will also be measured,
which may lead to unstable measurements.
Reject levelSets the range to measure when measuring the peak position of the received
light waveform.
Use the reject level to specify what the lower percentage of the received light
waveform to ignore during calculations.
If you specify a value that is too high, the measured value may be unstable
due to the surface status.
If you specify a value that is too low, diuse-reected light and noise will be
measured, which may lead to unstable measured values.
This range is used in the
measurement calculation.

Reject levelSets the range to measure when measuring the peak position of the received
light waveform.
Use the reject level to specify what the lower percentage of the received light
waveform to ignore during calculations.
If you specify a value that is too high, the measured value may be unstable
due to the surface status.
If you specify a value that is too low, diuse-reected light and noise will be
measured, which may lead to unstable measured values.
TargetSelect the measurement target from “Normal,” “Gap,” and “Semi-trans.”
“Normal” is standard.
Use this setting to specify what parts of the received light waveform to use
as measurement data.
The peak position of the received light waveform will be measured.
The center is measured, excluding the data from the point where the
amount of light is largest to the reject level.
Level dierences that have sudden height changes will be measured.
The measurement method is the same as the “Normal” setting, but two
measured values are output from one received light waveform.
Tips: The dierence in measured results for level dierences with the “Normal”
and “Gap” settings is shown below.
With the "Normal" setting, level dierence cannot be measured accurately. This can
be imporved by using the "Gap" setting as shown in the picture below:

When you specify the alarm limit, the specied number of prole values to
the right will be maintained.
If alarms occur repeatedly such that the specied number of values is
exceeded, an alarm (value outside of measurement range) occurs.
If you set "Alarm limit" to "HOLD," alarm state is not entered.
In the following gures, alarms are indicated with an "X," and thick lines are
used to indicate the parts in which the immediately preceding values are
maintained.

SmoothingPerforms averaging within the prole. Specify a setting of “1” to disable
averaging.
When you specify a setting of “2” or higher, the measured values to the
right — including the measured value at that position — will be averaged the
number of times specied by the averaging count.
If the target data causes an alarm, the corresponding value will not be
included in the averaging.

7.5.2 Save Master
Register the acquired prole as the master image.
The correction functions and comparisons with measured details
are set with the registered master image as the reference.
You can save one master image for each bank.
Tips:• When you change the reference coordinates for the height, position,
or tilt correction and when you change the correction procedure,
you have to register the master image again. If you do not register
the master image, the correction functions will not operate correctly.
When the target's position is shifted during measurement, you can correct
the position and height of the area.
With the Proler 2, you can correct the height, position, and tilt.
Do not use the correction functions when absolute positions are necessary
such as for web guide control.
Tips:• If the correction causes a part of that area to exit the settable range,
measurement will not be possible.

Set the reference to a height that will denitely be crossed by the master
image and by the prole during measurement.
2. Perform measurements.
Measure the points on the measured prole that have exceeded the

3. Perform corrections.
The area will be moved by just the amount that the measured waveform
and master image positions are shifted.
Tips:• If you specify a height for which there is no measured data in the master
image, the position correction is not performed.
• If there is no measured data at the specied height during measurement,
measurement is performed without correction.
• Perform position correction for convex proles like those described above.
Position correction may not operate correctly for concave surfaces.
• For level dierences, whether the correction will be performed appropri-
ately varies depending on the correction direction.
V correctSets the reference position. The height is adjusted so that it is equal
to the height of this position.
1. Set the reference position.
Set the reference position, corresponding to the master image, at which
correction will be performed. The height will be corrected so that it becomes
the same as that of the measured value at this position.
2. Perform measurements.
Measure the height at the reference position on the measured prole.
3. Perform corrections.
The area will be corrected by the amount of the height dierence between
the master image and the measured prole.
Tips:• If you specify a position at which an alarm occurs on the master prole,
the height correction is not performed.
• If an alarm occurs at the specied position during measurement, meas-
Tilt methodCorrects the installation tilt and the tilt of the measurement target object.
The prole tilt will be corrected so that the height correction reference
position and the tilt correction reference position become level with each
other. If an alarm occurs in either of the reference positions, the tilt correction will not be performed. In master image registration, the prole after tilt
correction is performed is registered. In tilt correction, the shape
of the prole is corrected. The area position is not corrected.
1. Set the height correction reference position.
This reference position is also used in tilt correction.
(The dotted line is the height correction reference position.)
2. Set the tilt correction reference position.
Set the reference position to the same height as the height correction
reference position. (The dotted line indicated by the arrow is the tilt
correction reference position.)
fter Correction
3. The correction is performed so that the two reference position
heights become the same.
The tilt correction is performed so that the two reference position
The Proler 2 sets “areas” within the measurement range, and then
performs measurements on these areas. You can specify up to four areas.
Sets the positions and sizes of the areas within the camera area.
Areas are rectangles. You can also specify areas so that they overlap.
Camera area

If the prole does not pass through the area, the measured result will
become "------ (measurement not possible)". Set the area so that measurement is possible.

Specifys the measurement functions for the areas.
You must congure dierent settings depending on the measurement
function.
Area
Prole
Average
The average of the measured values within the area are output.
Tips:• Parts where an alarm occurs will not be used in the calculation of the
average value.
• For locations where the measured value is larger or smaller than the
area, the measured values will not be used in the calculation of the
average value.
P height
The largest measured value within the area is output.
Tips:• Parts where an alarm occurs will be ignored.
• Within the range of the area, if there are measured values that are larger
than the area, the peak height value will be the upper limit of the area.
• The peak is determined by comparing the sizes of the measured values,
so when “Axis dir” is set to “Far+,” the peak will be in relation to the lower
part of the screen.
B height
The smallest measured value within the area is output.
Tips:• Parts where an alarm occurs will be ignored.
• Within the range of the area, if there are measured values that are
smaller than the area, the bottom height value will be the lower limit of
the area.
• The bottom is determined by comparing the sizes of the measured values, so when “Axis dir” is set to “Far+,” the bottom will be in relation
to the upper part of the screen.
The largest distance from the rightmost point to the leftmost point that
cross the center of the area's height is output.
Use this function when you want to nd the widths of protrusions and gaps.
Tips:• The points that are detected by the width function are the positions
that are detected by “Edge pos.”
P pos
The position of the highest measured value within the area is output.
Tips:• If there is an alarm within the area, the measured result will indicate
that measurement is not possible.
• Within the range of the area, if there are measured values that are
larger than the area, the measured result will indicate that measurement
is not possible.
• If there are multiple positions that are all the maximum value, the leftmost
position will be output.
• The peak is determined by comparing the sizes of the measured values, so when “Axis dir” is set to “Far+,” the peak will be in relation to the lower
part of the screen.
B pos
The position of the smallest measured value within the area is output.
Tips:• If there is an alarm within the area, the measured result will indicate
that measurement is not possible.
• Within the range of the area, if there are measured values that are smaller
than the area, the measured result will indicate that measurement is not
possible.
• If there are multiple positions that are all the minimum value, the leftmost
position will be output.
• The bottom is determined by comparing the sizes of the measured values,
so when “Axis dir” is set to “Far+,” the bottom will be in relation to the
The rightmost point or the leftmost point that crosses the center
of the area's height is output.
• Detection direction
Specify the direction from which to detect edges.
The gure to the right shows the detection result when detection from
the left is specied.
EdgeCount
The number of times that the prole crosses the center of the area's height
will be counted.
Tilt
A straight line approximating the prole within the area is determined,
and then the tilt of this straight line is measured.
The unit of the output value is degrees (°).
Tips:• If there is data for which measurement is not possible within the area,
the measured result will indicate that measurement is not possible.
• In order to perform the tilt measurement, the prole must cross the left
and right sides of the area (the thick-bordered frame). If the prole does
not cross both sides, the measured result will indicate that measurement
is not possible.
• To measure the angle, you have to use the “Calc” function.
([7.7 Calculation Settings])
Size
The mathematical area of the section bounded by the prole and the
specied height within the area is determined.
The unit of the output value is mathematical area (mm
• Direction
Select the direction in which to perform the mathematical area
measurement from “↑” (from the lower side of the area up) and “↓”
(from the upper side of the area down) in relation to the specied height.
The measurement areas for each of these settings are shown below.
(The arrows indicate the set mathematical area directions and the shaded-in parts indicate the measurement areas.)
Tips:• Mathematical area measurement results have up to three decimal plac-
Length
The line length of the prole within the area is determined.
The unit of the output value is length (mm).
Tips:• Because the line length is the same for the same prole,
Diameter
An approximate circle is determined from the measured values within
the area, and then the diameter of this circle is output.
The unit of the output value is length (mm).
es. The fourth decimal place is zero (0).
this function can be used to perform prole judgment.
R
• Direction
Select the direction in which to perform the measurement from “↑”
(from the lower side of the area up) and “↓” (from the upper side of the
area down). Indicate the convex direction of the arc to measure.
Tips:• In order to perform the diameter measurement, the prole must cross
the left and right sides of the area (the thick-bordered frame). If the
prole does not cross both sides, the measured result will indicate that
measurement is not possible.
• You can perform a more precise measurement by ensuring that the top
of the arc is positioned in the center of the area and by measuring over
a wide range.
Inect
When the curvature of the point of the prole meets or exceeds the level
set, output its position. When it can’t detect the point meets the level,
output result shows “----”.
Tips:• Inection graph is not available.
Sets the processing to perform in relation to the measured values
of each area.
Averaging is performed the number of times specied over the measured
results of the areas.
The more times specied for processing, the more stable the result,
but the response speed is slower.
[Setting target:] Areas 1 to 4
7.7.2 Hold
Tips:• If you have used “Smoothing” as described in “7.5.1 Prole Extraction
Settings,” the response speed will not be changed.
You can use hold mode to acquire the maximum or minimum value in the
specied length of time.
By detecting the maximum or minimum value while the workpiece passes
by, you can easily check for problems such as the occurrence of abnormal
values.
