Take inspection of your products to the next level by incorporating 3D inspection using the Cognex DS925B sensor. It combines a compact and rugged optical design with industry-leading Cognex vision software that includes a powerful 3D toolset.

Unlike traditional 2D machine vision, the DS925B 3D Displacement Sensor provides a topological representation of your part with 3D features that can be used to supplement 2D inspection data with measurements such as height, tilt and volume. The extra dimensional information can also be used to solve applications that may be challenging due to the part’s color.

Calibrated 3D Vision from Cognex

The factory-calibrated DS925B provides results in real units of measurement with micron-level accuracy, making 3D applications easier to use and quicker to deploy. Correction of mounting and motion errors is simple using Cognex field calibration techniques, allowing preservation of accuracy even with relaxed mechanical configurations. Field calibration also enables multiple DS925B sensors to be used in combination across wide production lines to generate single high resolution 3D images. Examples of applications solved using the DS925B sensor include:

  • Measuring component height, tilt and spacing to ensure correct assembly
  • Verifying depth of screw holes and machined slots in housings
  • Identifying surface defects and foreign debris introduced prior to assembly
  • Inspecting quality and quantity of glue and sealant dispense
