* Equipped with sensor controller ZG2-WDC_1A as standard.
12x the conventional sensitivity (Industry's best)
7x the conventional ambient illumination
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 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.
* For details, see descriptions of the APS function (Catalog) and new optical system ONPS (Catalog).
2.5x the conventional inclination tolerance (Industry’s best)
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.
* For details, see descriptions of the high-performance gauss lens (Catalog).
The ZG2 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.
The ZG2 can measure the step between the peak of a lens and lens holder to check if they are assembled properly.
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, see descriptions of high-speed multi sensitivity (Catalog).
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 provides the optimum solution for any intended purpose.
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.
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.
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.
Basic setting requires only three steps. Omron's unique interface maximizes the sensing performance with extremely simple operation.
* Screen images are simulated.
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.
The position and inclination are automatically corrected even for targets for which positioning is difficult. This helps to perform stable in-line measurement.
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, see System Configuration (Catalog).
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.

the measurement object is higher than that of the measurement object.

This is not a guaranteed value.
*6. Protection structure of connector area is IP40.
