6For Your Safety
2. For Your Safety
2.1 Use for Intended Purpose
The product is based on the following functional principle:
2D/3D Profile Sensors project a laser line (1) onto the object to be detected (2) and generate an accurate,
linearized height profile with an internal camera (3) which is set up at a triangulation angle (4).
Thanks to its uniform, open interface, the weCat3D series can be incorporated by means of the DLL (Win-
dows)/so (Linux) or the GigE Vision standard without an additional control unit. Alternatively, wenglor offers
its own software packages for implementing your application. Individualized selection from a great variety of
working ranges, laser classes and light types (red and blue light) ensures maximized flexibility for two and
three-dimensional object detection.
The weCat3D range of sensors is subdivided into two performance classes: weCat3D MLSL and weCat3D
MLWL. Whereas the weCat3D MLSL provides for high performance in standard applications with its compact
design, the weCat3D MLWL assures maximized, top performance.
The weCat3D MLSL is distinguished by minimal weight and a space-saving housing. Up to 3.6 million
measuring points per second, an output rate of up to 4000 Hz, visual field widths from 27 to 1350 mm, high
resolution (down to 22 µm in visual field width X and down to 3.3 µm in working distance Z) deliver outstand-
ing performance.
The weCat3D MLWL is distinguished by previously unparalleled performance characteristics: up to 12 million
measuring points per second, 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) impressively
demonstrate the breathtaking high performance and precision of this product range.
