The high-precision surfaceCONTROL 3D 3500 snapshot sensor is employed for automated optical inspection of surfaces, shape, and geometry on diffuse reflective surfaces. It allows for the processing of data at high speeds and with accuracy.
It is compact, and with a z-axis repeatability up to 0.25 µm, the sensor sets a new benchmark in high-precision inline 3D measurements. This allows for reliably detecting even the smallest deviations in height and flatness. The system has two models to cover various measuring fields.

The sensor has a digital I/O interface. Quick data output is ensured via Gigabit Ethernet. It supports EtherCAT, PROFINET, and EtherNet/IP connections due to the presence of the 2D/3D Gateway II feature. Advanced software tools allow for precise surface inspections and 3D measurements. The sensor’s compatibility with GigE Vision enables seamless integration with third-party image processing software. The software package also has an SDK for integrating customer software.
