Copy Counting for Printed Products via Jump Detection with Triangulation Laser Distance Sensors
In the printing industry, newspapers and magazines are conveyed on conveyor belts in what is known as a shingle stream, i.e. overlapping. The copies must be counted so that the downstream packaging unit can process the exact quantity. Since they lie on top of each other and vary in thickness, detection must take place independently of the absolute distance to the sensor. A triangulation laser sensor mounted above the conveyor belt reliably detects the units thanks to the integrated jump detection function. In this operating mode, the sensor reacts to measured value jumps on the folds.

Double Layer Detection of Sheet Metal and Body Parts by Laser Distance Sensors Triangulation
In the automotive industry, sheet metal parts are taken from a stock by a robot gripper and fed to the welding robot. Several sheets can stick together due to adherent oil, wedging of the sheets or magnetic charge. To ensure that only one sheet is gripped per assembly process, two laser distance sensors triangulation are mounted at opposite positions. The sensors measure the distance to the sheet and then calculate the sheet thickness via a difference calculation. If this result is greater than that of an individual sheet, a signal is output.

Component Detection in Insertion Stations via Laser Distance Sensors Triangulation
Metal components are welded fully automatically in car body construction. After the base plate has been placed into a positioning and clamping device, the fixture plate to be welded is positioned on a centering mandrel. A laser distance sensor triangulation now checks the position of the plate. The so-called window teach mode enables the sensor to detect the component within a defined tolerance window of ±2.5 mm. This ensures reliable position detection and process-reliable welding even in the event of slight position deviations.

Measurement of Soldering Paste in SMD Soldering Systems by Laser Distance Sensors Triangulation
In reflow soldering, soldering paste is applied through the openings of a template to the intended contact surfaces of a PCB using a scraper. During this process, the height of the solder paste between the two scrapers must be continuously monitored. To measure the paste height, laser distance sensors triangulation are used to precisely measure the current height of the solder paste and automatically regulate the redosing. If the paste level drops below a defined threshold value, solder paste is automatically added. This ensures an even flow of material.

Position Control of Shiny Metal Components by Laser Distance Sensors Triangulation
In the manufacture of miniature circuit breakers (MCBs), also known as automatic circuit breakers, the individual components are first positioned manually by the operator on a rotating device and then welded automatically. Four laser distance sensors triangulation reliably check whether all components are correctly and completely positioned on the device. The welding process only starts if the detection is correct. The high measuring accuracy of the sensors ensures interference-free detection of shiny components, even under difficult conditions.

Can Position Monitoring on High-Performance Transport Systems Using Laser Distance Sensors Triangulation
To avoid disruptions in the production process, cans must be placed with the opening facing up during production and the filling process in high-performance transport systems. Horizontal or missing cans must therefore be detected in good time. Several laser distance sensors triangulation are installed above the conveyor line for this purpose. These sensors reliably monitor all conveyor lines simultaneously and check the correct position of the cans via distance and intensity measurements. Misalignments and empty transport sections are thus detected early and can be corrected in good time.

Leading Edge Detection in Cutting Machines by Laser Distance Sensors Triangulation
Portions of sausage and cheese cut by high-performance slicing machines must be precisely positioned and aligned on the conveyor belt so that they can be placed into the packages with exact accuracy. To precisely control the conveyor belt, laser distance sensors triangulation detect the leading edges of the portions at three points: after cutting, before layering and after joining. Thanks to the fine laser beam and the jump height detection, the sensors reliably detect the thin slices on the slightly oscillating conveyor belts. This enables exact timing.

Shape Monitoring of Corrugated Cardboard via Laser Distance Sensors Triangulation
During corrugated cardboard production, the corrugated profile of the cardboard must be measured continuously. Several laser distance sensors triangulation installed next to each other monitor the profile and thus ensure consistent product quality – even at very high production speeds. Due to their high accuracy, the sensors also reliably detect corrugated cardboard of different colors, surfaces and brightnesses. Permanent monitoring and dynamic adjustment of the processes allow deformations to be detected at an early stage and corrected quickly.

Presence Check of Wooden Panels in Furniture Production with Ultrasonic Distance Sensors
In the furniture industry, wooden panels with different colors, shapes, degrees of gloss and surfaces are conveyed on roller conveyor belts to the next process step. In order to monitor the transport fully automatically, the presence of the panels must be recorded at all times. The slim metric design allows installation beneath the conveyor technology in order to be able to carry out a precise presence check of the wooden panels. Even dust and chips do not influence the results of the ultrasonic sensors.

Flow Monitoring in Liquid Cooling Systems with Flow Sensors
To prevent outages and overheating at an early stage, reliable water cooling must be ensured in data centers. The cooling system consists of two circuits: In the primary circuit, the heated coolant is directed from the data center to external cooling units to cool them. The cooled liquid is then returned to the servers in the secondary circuit. Flow and pressure sensors are installed in the piping in both circuits. These monitor the flow, water temperature and water pressure continuously and precisely.

Detection of Print Marks on Tea Packaging via Contrast Sensors
Before tea bags can be filled, they must first be folded into their characteristic tea bag shape. To ensure that all packaging is uniform, print marks are applied to the packaging films. A contrast sensor reliably detects the marks through a small, round white light spot to monitor the folding, gluing and cutting process. Its small, compact 1M design makes it ideal for use in confined spaces.

Detection of Contrast Marks on Chocolate Packaging Using Contrast Sensors
In the packaging industry, chocolate is packaged in tubular bags on horizontal packaging machines. To ensure that each package is the same size, contrast marks are applied to the foil packaging. A contrast sensor reliably detects these marks at high belt speeds. This allows the foil cutting process to be precisely controlled. Thanks to their compact format and universal mounting options, the sensors can be optimally integrated into small packaging systems even in confined spaces.
