The Applications

1. High-Speed Carton Counting on Automated Conveyors

In automated packaging lines, cartons move rapidly with very small gaps between products, which makes accurate counting difficult. The WS/WE100L-F1131 is installed as a through-beam sensor across the conveyor to generate a clean detection line. Its laser-based beam and extremely fast response time allow each carton edge to be detected precisely, even at high throughput. The narrow beam profile avoids false signals caused by vibration or background objects. This enables reliable counting, correct timing for downstream equipment, and smoother operation without production slowdowns.

2. Small Component Detection in Electronics Assembly Lines

Electronics production often requires detecting tiny components moving quickly between assembly stations. Standard photoelectric sensors can struggle with low contrast or minimal object size. The WS/WE100L-F1131 overcomes this by using a focused laser beam that reliably detects small parts regardless of surface color. Adjustable sensitivity allows the sensor to be tuned for different component dimensions. This improves part presence verification, reduces assembly errors, and ensures stable operation in high-speed automated insertion and handling systems.

3. Pallet and Tote Positioning in Intralogistics Systems

In automated warehouses, pallets and totes must be detected accurately to control conveyors, lifts, and transfer points. The WS/WE100L-F1131 is mounted across transport paths to confirm correct load positioning before movement. Its long sensing distance supports wide conveyor layouts, while the laser beam ensures precise detection in large open areas. Fast switching allows immediate control responses, helping prevent misrouting, collisions, and unnecessary system stops in busy intralogistics environments.

4. Film and Sheet Edge Detection in Packaging Machinery

Packaging equipment handling thin films or flat sheets requires precise edge monitoring to maintain alignment and cutting accuracy. The WS/WE100L-F1131 is used to detect material edges as they move continuously through the machine. The laser through-beam principle provides stable sensing of thin or low-profile materials that are difficult to detect with conventional methods. Rapid response enables quick corrective action, reducing material waste and maintaining consistent packaging quality.
