Dominance in 70 Models.

  • Measuring ranges from 30 to 1300 mm in the X direction
  • Maximum resolution: 2.0 µm in the Z direction
  • Up to 12 million measuring points per second

weCat3D MLSL

The weCat3D MLSL is distinguished by it minimal weight of just 300 g and a space-saving housing (90 x 36 x 64 mm). Up to 3.6 million measuring points per second, an output rate of up to 4000 Hz, and highly precise resolution (up to 22 µm in visual field width X and up to 3.3 µm in working distance Z) deliver outstanding performance.


The weCat3D MLWL is distinguished by internationally unique performance characteristics: up to 12 million measuring points per second, an output rate of up to 6000 Hz, field widths from 30 to 1300 mm and maximum resolution (up to 17 µm in visual field width X and up to 2.0 µm in working distance Z) impressively demonstrate the breathtaking power and precision of this product range.

Laser Triangulation – How weCat3D Works

The 2D/3D Profile Sensors included in the weCat3D series take advantage of the laser triangulation measuring method. A laser line is projected onto the object to be measured. The camera integrated into the sensor records this line via the triangulation angle. The sensor is thus capable of generating a precise height profile. Stringing these 2D profiles together makes it possible to generate a 3D point cloud.

weCat3D Sensors are available with red or blue laser light in laser classes 1, 2M, 3R and 3B.

Maximum Performance in Detail

The weCat3D series offers a large dynamic range
almost independent of the color and the brightness of the objects.

wecat3D Sensors generate strong measuring signals
even on reflecting surfaces like metal.

Thanks to its extremely large resolution in Z (working range) and X (width field of vision), the weCat3D Sensors detect smallest components reliably.

The 2D/3D Profile Sensors of the weCat3D series
provide reliable data on metallic and glossy surfaces.

In addition to the 3D data, simultaneous acquisition of signal strength by weCat3D sensors permits the generation of high-contrast gray tone images. These can be used, for example, for the detection of data matrix codes and barcodes or contamination on objects – without any additional hardware.
