2D - A two directional (X-Y) coordinate system for defining and measuring parts, see figure below. It is used whether drawing by hand, or modern (CADD) programs. 2D also describes the format of resulting drawings, and is further used to develop code to guide CNC-based machines code, see G-code

2D CAD file - Using computer programs, engineers draw two-dimensional models (drawings) of machinery and parts. Clients use CAD software to design their parts and machines. SoftNoze has 2D geometric files of the sensor mounting components, such as sensor conduit adapters, fasteners, brackets, shields and protective sensor covers. Clients can request files to confirm dimensions for machine building tasks. Typical 2D formats are DWG (.dwg) and DXF(.dxf).

3D - A coordinate system for defining and measuring parts in three dimensions using an "X-Y-Z" system, see figure below. Using 3D, parts are described by, depth, width and height. Computer design programs such as CADD and solid modeling software can create life-like models, and another step allows simulation so sensors, sensor brackets and machines can be seen on computer prior to machine building.

3D CAD file - Shown below are images of 3D CAD files of sensor brackets and mounting components. They're are used to


3D models - In computer graphics, software programs allow creation of 3D models using a process that allows a user to develop a mathematical representation of a three-dimensional object. The rendering of the part’s surfaces is called a 3D model. SoftNoze supply 3D files of sensor brackets, which allows clients to design virtual models of their machine designs. Also see "3D CAD file" above.

303/304 - See Stainless steel, 303/304

314/316 - See Stainless steel, 316/318

2D Code reader - A machine vision sensor for object recognition, cameras with application-specific evaluation, i.e. reliable electronic eyes at a low cost and a high degree of integration. Often packaged in an industrially compatible housing that combines; lighting, lens, camera chip, evaluation and process connections for the integration in the higher-level controller.

3D Cameras - 3D cameras detect scenes and objects in their spatial dimensions at a glance. In contrast to laser scanners they do not require moving components and are thus robust and wear-free. They have a chip matrix whose pixels evaluate the distance to the object. The image of the object on the chip matrix and the respective distance values correspond to a 3D image. Besides the 3D distance image the camera provides a grey image of the scene. The combination of these images offers the possibility to freely program application-specific tasks by means of a software development kit.

3D Sensors - 3D sensors are special camera systems to asses object characteristics in three dimensions. They have a chip matrix whose pixels evaluate the distance to the object. The image of the object on the chip matrix and the respective distance values correspond to a 3D image. The integrated evaluation enables the detailed assessment of the object's or scene's conditions, for example by means of volume, distance or level detection in three dimensions.

6061 - Type, alloy, of aluminum metal, see Alluminum, 6061 for more complete discription.
