Presence Check of Steel Sheets on Roller Conveyors by Inductive Sensors with Increased Switching Distances
In the steel industry, the presence of steel plates before and after rolling or punching processes must be checked. For this purpose, the sheets are transported on roller conveyors and reliably detected at their outlet by an inductive sensor with increased switching distance. Height fluctuations of the sheet are compensated by the high switching distance. The sensor with integrated error indicator is ideal for harsh industrial environments thanks to its rugged M18 enclosure and IP67 degree of protection and can be mounted in a few simple steps.

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.

Pin Check in Plug Production via Dark Field Illumination
When manufacturing plugs, it must be checked whether the correct number of pins are present and whether these pins are in the correct position. For this purpose, dark field illumination, consisting of a modular ring light and a dark field attachment, is attached together with a smart camera at a short distance in front of the products to be tested. Due to the very low angle of incidence (60°) of the light output, the illumination ensures the dark field effect and thus optimal illumination of the pin tips.

Position Monitoring of Membranes on FFP3 Masks With Breathing Valve with Vision System
FFP3 masks must be monitored during the manufacturing process to ensure reliable function. During this process, it must be checked whether the integrated membranes are correctly inserted before the sealing caps are applied. The membrane must not protrude and must be flush with the frame. For this purpose, a vision system is installed which checks both the position and the diameter of the membrane. The system consists of a machine vision camera, an analysis module (control unit) and a ring light. If the tolerance is exceeded, the mask is rejected.

Detection of the Foil End via Contrast Sensors
In the pharmaceutical industry, pills and tablets are packaged in blister packs to protect them from environmental influences, atmospheric oxygen or moisture. The packaging consists of foils that are unwound from the rolls during the production process. The end of the foil is marked with a marking adhesive strip. To ensure a continuous flow of material, contrast sensors detect this marking and can thus initiate a roll change. Thanks to the integrated jump detection, markings of different colors on different materials are reliably detected.

Detection of Contrast Marks on Foils via Contrast Sensors
Packaging for loose products, granules or difficult-to-process products is produced in vertical packaging machines (VFFS). To ensure that a product line has the same package size, contrast marks, also known as print marks, are applied to the foil material. Contrast sensors detect the contrast marks and can thus control the packaging process by sealing. This ensures consistent quality and package size.

Print Mark Detection on Label Foil via Contrast Sensors
In the packaging industry, products are packaged in tubular bags on horizontal packaging machines. For exact package sizes, black print marks are applied to the foils, which are detected by contrast sensors and control the cutting process of the foil packaging. The sensors detect the marks despite frequent batch changes and different color combinations on the foil. Thanks to the integrated contrast mode, the print marks can also be reliably detected on a patterned background.

Contrast Marking Detection on Transparent Cosmetic Tubes via Contrast Sensors
During automatic filling of tubes in the cosmetics and packaging industry, the tubes must be precisely aligned before filling. Contrast sensors are used for precise positioning. The sensors reliably recognize the contrast markings applied to the round tubes, also known as print marks. Thanks to the white light used, reliable detection of the contrast marking is also guaranteed for semi-transparent tubes. The IO-Link and the integrated display also enable the quality of the mark to be continuously monitored and the filling process optimally supported.

Cap Detection on Plastic Bottles with Inductive Sensors in Full-Metal Housing
In the beverage industry, aluminum hygiene seals are often applied to plastic bottles before the end cap is screwed on. Once the aluminum caps have been applied, their presence must be checked. For this purpose, an inductive sensor with full-metal housing is installed directly on the dispenser, which detects the seals. Thanks to the hygienic stainless steel 316L and the high IP69K degree of protection, the sensor is resistant to high pressure and cleaning agents, making it ideal for the beverage industry.

Track & Trace in the Food Industry with RFID Readers
In the food industry, traceability of products must be ensured at every stage of the manufacturing and processing process. RFID transponders are fitted to food trays for moving the food through the production process. The RFID readers fitted between the roller conveyors register the transponders on the passing trays and read and write new data on them. The plastic sheathing protects the RFID chip from possible damage.

RFID Recognition and Control of Workpiece Carriers
In special machine construction, workpiece carriers run through various processes in one system. RFID readers are installed at several points in the system so that the workpiece carriers are reliably detected and identified at each station. The transponder mounted on the workpiece carrier is recorded and read by the reader and can be written with new process information to trigger subsequent processes. This ensures the traceability of the processing. Thanks to their compact format, the readers can be mounted in tight spaces or harsh environments.

Distance Measurement of Battery Modules for Handling Processes Using Triangulation Laser Distance Sensors
During automated production of battery modules in the automotive industry, individual cells are stacked on top of each other to form multi-part units. Before robot arms can grip them, the exact distance to the module must be measured – accurate to a few tenths of a millimeter. A triangulation laser distance sensor is installed on the gripper unit per module for this purpose, which precisely records the distance values despite the highly reflective battery surfaces and transmits them to the gripper.
