A wide laser beam captur esentire shapes with ease.
A new Smart Sensor debuts with a light-section method that visualizes cross-sectional shapes.
Three basic steps
An advanced interface maximizes the sensing performance with extremely simple operation.
1st Display the profile.
The profile is displayed as soon as the power is turned ON.*
The Sensor Head position can be adjusted while viewing the profile on the screen.
*In FUN mode.
2nd Select the measurement item.
Select the icon for the item to be measured, such as height, step, or cross-sectional area.
3rd Designate the measurement range.
Simply enclose the range to be measured with the box. The ZG automatically optimizes the sensing conditions.
*Screen images are simulated.
High-speed Inspection
High-speed, continuous sampling meets the needs of processes where speed is required.
Inspecting fluid application for formed-in-place gaskets (FIPG) (ZG-WDS22/70)
Measure continuous motion on a robot arm
Continuously output profiles
High-speed processing technology
Equipped with the PI-Express image processing core engine. (Newly developed)
Principle
All processing is done digitally, from sensing input to output. The generation of shape profile data and measurement functions that were conventionally handled by a microprocessor are built into a single chip.
Use of the newly developed PI Express (see note) LSI speeds up processing and saves space.
Note:Profile- Image-Express
Effect
The response time required from receiving an external input (trigger) to outputting complete profile data via USB is 100 ms (see note) maximum.
Note:Varies depending on the measurement mode.
Highprecision Shape Measurement
The shape of the measurement object is completely reproduced with high precision.

High-precision measurement of the width of grooves during vehicle assembly
Multi-sensitivity Function (Patent Pending)
When a laser is directed at a complicated shape, the light often does not effectively reflect from parts on which the beam strikes at an angle.
This causes a part of the profile to be lost and makes it impossible to reproduce the shape.
The multi-sensitivity function of the ZG-series 2D Shape Sensors determines the optimal sensitivity for each line to reproduce the shape profile.
Principle
While switching sensitivity levels for workpieces with reflectivity that varies from part to part, the Sensor inputs multiple images and combines them into a single image with the optimal sensitivity for each part. This produces an image of the entire workpiece.
Example: A mountain-shaped workpiece in which the reflectivity varies from that of the reference plane.
Effect
Simple Shape Measurement
Teaching enables simple shape distinguishing and positioning.
Distinguishing the shape of a pin boss (ZG-WDS22)
Convex or concave pin bosses can be easily distinguished.
Checking the shape of vehicle structural parts (ZG-WDS22)
The wide beam allows vehicle structural parts to be measured in a single operation.
Reflective-type Sensor
Installs easily just about anywhere.
The wide beam enables stable, reflective measurement when mounting limitations do not allow a through-beam configuration to be used or when measuring the ends of warped panels, which is difficult for through-beam systems.
Highprecision Displacement Sensor
Virtually any object can be measured.
The advantages of the wide beam are not limited to shape measurement. The line beam averages slightly irregular reflections from a bumpy surface to provide a level of precision that was not possible with conventional displacement sensors.

Flexible Mode Selection - From High Speed to High Precision
Flexible Measurement Technology (Patent Pending)
Principle
Light-section method
Effect
Functions to alter the measuring precision in the displacement direction and change the sampling period are provided for the first time on a displacement sensor using the light-section method.
Also, installation is easy because the measurement center distance remains fixed even when the measurement made is changed.
High-speed Mode
A fast 5 ms satisfies the needs of processes that require speed.
Measuring chip height above a lead frame (ZG-WDS3)
High-precision Mode
Completely reproduces the shape of the measurement object to measure with high precision.
Measuring the shape of air-bag grooves (ZG-WDS8)
Trigger Synch Measurement
Featuring an operation mode that calculates the measurement value in synch with the command input!
An external command (parallel input with USB 2.0 or RS-232C) can be used in either the fixed or multi sensitivity mode to obtain data at the desired timing.
Conventional model
It was not possible to designate the timing for external measurement requests.
Z G
Measurement values can be obtained for specific measurement cycles in response to external measurement requests.
The Inspection Status Is Immediately Visible
A Compact, All-in-one Controller with LCD Monitor
Sensor-captured status is completely reproduced as a profile.
The multifunctional Controller has been condensed to the industry's smallest size so it can be installed wherever it is required, to give precisely the number of inspections that are necessary.
Enlarged Display of Profiles on a Personal Computer
Smart Monitor ZG Setup Support Software
Using the included Smart Monitor ZG Setup Support Software (see note), intricate profiles that cannot be sufficiently checked on the Controller's LCD monitor can be displayed and checked on the large screen of a personal computer.
