High-precision series of 3D snapshot sensors offers larger measuring range

19-02-2024 | Micro-Epsilon | Industrial

Micro-Epsilon has extended its surfaceCONTROL range of high-precision 3D snapshot measurement sensors for automated, inline measurement of geometry, shape and surface quality of objects. The surfaceCONTROL 3xx0-240 provides a larger measuring range of 240mm and a measurement area of up to 245mm x 180mm. The sensor supplies the best measurement results at a z-axis distance of between 340mm and 540mm.

The device is a 3D snapshot sensor with a compact design and exceptionally high resolution in the z-axis. With its high repeatability combined with the larger measuring area and measuring range, the sensor sets a new benchmark in high-precision 3D measurement technology.

The sensor is obtainable in all classes and models of the surfaceCONTROL 3xx0 series, i.e., the surfaceCONTROL 3D 3200 and surfaceCONTROL 3D 3500 ranges, each providing a different measuring area and depth of field. Both models are fully integrated industrial sensors protected to IP67 with passive cooling (active cooling is available for higher operating temperatures).

The surfaceCONTROL 3D 3500 delivers the highest z-axis repeatability of up to 0.4µm and the best z-axis resolution of 1µm. A high data processing speed of up to 2.2 million 3D points per second allows the sensor to increase productivity in the respective application.

The surfaceCONTROL 3D 3200 is a more affordable version of the surfaceCONTROL 3D 3500 but still provides many similar technical performance benefits. The surfaceCONTROL 3D 3200-240 offers a high z-axis repeatability of up to 0.6µm and a high z-axis resolution of 1.5µm. With data acquisition times from 0.3s, the sensor is ideal for many industrial applications.

The sensor is suitable for a wide range of flatness measurement, coplanarity measurement and surface defect detection applications, including flatness inspection of circuit boards; planarity inspection of unpopulated PCB substrates; completeness check of electronic components on fitted PCBs; 3D measurement of high precision mechanical parts; width, tilt angle and position measurement of rivets; detection and evaluation of breaks on clutch discs; 3D text recognition of embossments that cannot be solved utilising 2D image processing due to lack of contrast; inspection of height and thickness of adhesive beading on smartphone shells; and determination of shape deviation defects on injection moulded parts.

These 3D systems support the latest GigE Vision and GenICam standards for straightforward integration into third-party image processing software. A comprehensive SDK is also available that enables customers to develop their own analysis software. Also included in the scope of supply is the company’s 3D View software, which offers a convenient user interface for surfaceCONTROL sensors. The software enables fast commissioning, evaluation of the sensor, set up and optimisation of parameters, and provides the correct positioning of the measuring object.
