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.
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.
