Sensor for 3-dimensional object detection
November 2016, Sensors & Transducers
Wenglor, has developed sensors that can scan and evaluate objects in 3D. The weCat3D profile sensors allow data to be either read out directly as measured values or used for rapid further processing of the point cloud. 3D calculation of volume is of great value in industries such as food, machinery manufacturing, woodworking, electronics, automotive and pharmaceutical, where precise compliance to weight and geometric specifications are demanded.
More than 12 million measuring points per second
The weCat3D series works with a visual field width within a range of 30 to 1300 mm in the horizontal X-axis and is capable of detecting differences in height of just 2 μm within the working range at a rate of 3,6 to 12 million measuring points per second. Available laser classes (1, 2M, 3R, 3B) and two selectable types of light (red, blue) result in a diverse product portfolio of more than 70 models.
Two performance classes and a thousand possibilities
With a weight of just 300 g and a space-saving housing, the model weCat3D MLSL scans as many as 3.6 million measuring points/sec, has an output range of up to 4000 Hz, as well as a resolution of down to 22 μm in visual field width X and down to 3,3 μm in working distance Z.
The model weCat3D MLWL scans up to 12 million measuring points/sec, has an output rate of up to 6000 Hz, visual field widths from 30 to 1300 mm and high resolution down to 17 μm in visual field width X and down to 2,0 μm in working distance Z.
Due to this extremely high resolution in the Z and X directions, the sensors can detect the smallest components in the micron range such as those used in PCB assembly. The special algorithms allow the sensors to generate powerful measuring signals and top quality profile data that is not impaired by glossy, reflective surfaces such as metals. The high dynamic range ensures that objects can be precisely measured almost independent of colour and brightness.
