Easier and much more accurate for
profile measurement
Stable measurement regardless of color, material, and shape complexity
<Simple configuration>
Plug & play! Just connecting Sensor head and Controller.
*Equipped with sensor controller ZG2-WDC_1A as standard.
A wide variety of
profile measurement items
Painted object and black
rubber
(Industry's best) 12x the
conventional sensitivity
Dark colored materials or materials with a matt finish, like black
rubber often do not reflect sufficient light to maintain a stable
measurement. They are also susceptible to the influences of ambient
light so are difficult to measure using conventional laser measurement
sensors. The ZG2 2D Laser Profile Measurement Sensor solves these problems because it is supersensitive
and significantly reduces ambient noise. It also has an APS function
to automatically tune parameters such as a receiver’s sensitivity and
background suppression level at optimal levels according to the
ambient light conditions. Shape profiles can also be easily reproduced
at optimal conditions to achieve high precision measurement.
Measurement of moving objects is possible because measurement can be
performed within a short exposure time.

Inclined transparent object or glossy object
On an object with strong regular reflection components such as luster
sides and transparent objects, the amount of light reflection
significantly reduces when the object is slightly inclined, lowering
measurement stability. The sensor head ZG2-WDS3VT with a
high-performance gauss lens is the solution for the problem. Its
inclination acceptance range has been increased to 2.5 times as
compared to conventional models so transparent objects can be measured
up to a ±5° inclination at a stable level. Because the ZG2 has this
function, it is useful for assembly inspections for lenses and glass
plates.

Assembly inspection of electronic parts
The ZG2 2D Laser Profile Measurement Sensor can measure parts with glass or a glossy object such as CCDs,
CMOSs, and crystal splinters of quartz resonators at a stable level.
It can be used for assembly inspections of parts because it can
measure steps on a substrate or package side.
Assembly inspection of lenses
The ZG2 2D Laser Profile Measurement System can measure the step between the peak of a lens and lens
holder to check if they are assembled properly.
High-speed takt-time line
10x the conventional speed
Reproducing a clear, stable profile is difficult for objects with both
black and metal sides, cylindrical objects, and complex-shaped objects
because the amount of laser reflection and reflection angle differ
according to the positions of different materials on such objects. To
solve the problem, Omron's unique "multi-sensitivity function" has
been improved. The measurement speed for the function has been
increased so that the function can be used in high-speed takt-time
lines.
* For details, refer to Data Sheet.
Measurement of wide target
Two sensor controllers are linked and two sensor heads perform
synchronous measurement to increase the measurement range to 140 mm.
With the link method, the ZG2 Series 2D Laser Profile Measurement
Sensor provides the optimum solution for
any intended purpose.
Measurement by finding the inflection point of the object
The sensor has a measurement function to capture points where an angle
varies on a target as an "inflection point." This function enables the
measurement of a step or edge width of a feature point of a target.
Measurement of position and angle of intersection
The sensor has a function to measure the "intersection coordinates"
and "intersection angle" on two linear lines on a target. An example
of a useful application of this function is tracer control for a
welding torch for targets to be welded.
Installation/Setup
Simplified Sensor Head Adjustment
The "installation correction function" automatically makes adjustments
to parallelly align the sensor head with the target. The function
eliminates the gap between the reference plane and sensor head
inclination caused during setup and in turn significantly reduces the
time spent for adjustment during the setup of the sensor head.
* When inclination is great, a measurement error may occur. Check the
measurement accuracy in actual measurement conditions prior to use.
Intuitive setting
Basic setting requires only three steps. Omron's unique interface
maximizes the sensing performance with extremely simple operation.
* Screen images are simulated.
Measurement
Simultaneous measurement of two or more points
Measurements can be performed for up to eight measurement points
selected from a profile simultaneously so different types of
inspections can be carried out at the same time when necessary.
Measurement items can be selected from among 20 items including edge
width, height, inclination, step, and sectional area according to the
intended purpose.
Active Position Compensation Control
The position and inclination are automatically corrected even for
targets for which positioning is difficult. This helps to perform
stable in-line measurement.
Operation
Data Storage and Trend Analysis
A data storage unit is now available for storing measurement values
and profile data.
Data can be loaded on a PC from a memory card or via serial
communication and can be used to manage manufacturing history, monitor
tendency, or analyze defects.
* For logging capacity, refer to Data Sheet.
Large Program Capacity
Measurement conditions for up to 16 items (16 banks) can be registered
in the sensor controller unit. Banks can be easily switched by
inputting a signal, inputting a command, or operating a key. When the
data storage unit is used, up to 4,096 banks can be registered for
quick response to flexible production lines.
