¹ Only available when binning is enabled in the camera settings.

² Z repeatability is measured an average of 100 times over a pointcloud using a 4×4 mm area, at the middle of the measurement range.

³ Z linearity is the maximum deviation of 250 position measurements on the measurement range, where a measurement is the average of 2 profiles using the standard Cognex target.

⁴ Mounted to a 400 mm aluminum bar along the camera’s fins (parallel to the camera) on top of the vision system.

Software

Simplify complex applications without losing functionality

The 3D-L4000 laser displacement sensor is programmed using VisionPro software. VisionPro is a PC-based development environment that enables users to automate a wide range of functions, from inspection and identification to measurement and alignment. A full library of vision tools, combined with the intuitive QuickBuild interface, offers fast, flexible job configuration.

The easy-to-use QuickBuild interface provides a graphical approach to application development, allowing users to visually define and tune their application, without special programming or coding. Modular tool blocks allow users to create and reuse components, further simplifying setup and shortening cycle times.

For more challenging vision tasks, the QuickBuild interface offers advanced scripting and provides .NET C# programming options for additional flexibility in building custom applications or manually configuring jobs by code. 3D-L4000 with VisionPro is also compatible with Cognex Designer.

Application

Manufacturers, machine builders, and system integrators across all industries deploy 3D-L4000 laser displacement sensors to automate inspection, guidance, and measurement applications. These industry-agnostic solutions make it simple to integrate automation into any factory setting.
