Width Measurement of Profiles with Glass Fiber Optic Light Curtains and Fiber-Optic Amplifiers
Width Measurement of Profiles with Glass Fiber Optic Light Curtains and Fiber-Optic Amplifiers
In the production of metal profiles, the presence and dimensions of the objects must be detected before a clamping device secures them in place. Profiles can be black, white, chrome, glossy or matt. Glass fiber optic light curtains based on the transmitter-receiver principle are used in confined spaces, together with a universal reflex sensor. The optical fibers are arranged in a single line to create a light band. The width is measured, the linear signal is output proportional to the glass fiber cover and the correct position is determined.

Distance Calculation for Cheeses with Time-of-Flight Laser Distance Sensors
Distance Calculation for Cheeses with Time-of-Flight Laser Distance Sensors
During the production and processing of cheeses, the rind is removed in a robot-assisted process and the cheese is freshly coated. In order to determine the exact distance between the mounted tool and the object, a Time-of-Flight laser distance sensor in a stainless steel 316L housing is installed directly on the robot. The sensor is ideal for this purpose thanks to its low weight. For washdown areas, it is also essential to have a cleaning-agent resistant, leak-proof housing and IP69K degree of protection. Thanks to wintec, glossy and wet objects can also be reliably detected at an angle.

2D Code
A 2D code, also known as a two-dimensional code, consists of a pattern of dark and light elements (bars, rectangles and squares with corresponding spaces in between) which are arranged in a 2D fashion. 2D codes have a more complex layout than 1D codes, and the technology required for acquiring and deciphering them is more complex as well as the scanner must always read the entire pattern depicted by the barcode in order to acquire and decipher 2D codes, and not just a horizontal line as is the case with 1D Codes. Two-dimensional codes contain more diverse information than one-dimensional codes, for example information for the identification of products, texts such as addresses, and delivery note numbers. In general, we differentiate within the 2D codes between the stacked codes (stacked code) and the matrix codes (DataMatrix code).
