In modern labeling systems, maintaining accurate detection of fast-moving, transparent labels is a major challenge. The WF50-40B410 solves this with its ultra-fast response time and fine 0.2 mm detection capability. The integrated fork design eliminates alignment errors between emitter and receiver, reducing setup effort. Its stable infrared light ensures consistent performance under bright ambient conditions, preventing missed detections and ensuring every label is applied precisely on high-speed packaging conveyors.
During film or foil processing, accurate edge tracking is critical for maintaining product alignment. The WF50-40B410 provides stable detection even on clear or glossy films thanks to its infrared beam and precise optical alignment. Its 50 mm fork width accommodates a variety of web materials while offering instantaneous feedback at high speeds. This improves cutting and lamination precision, reduces material waste, and ensures smooth operation in automated web-handling systems.
Automated assembly lines often require reliable detection of very small objects such as electronic leads or metal pins. The WF50-40B410 delivers this precision with its 0.2 mm detection capability and 10 kHz switching frequency. Its compact size allows easy integration into tight spaces, while the IP65-rated aluminum body withstands industrial vibration and dust. This ensures accurate part counting, presence verification, and process control in micro-assembly and electronics production.
In print-finishing or paper converting lines, the WF50-40B410 is ideal for identifying perforations, punched holes, or slots in moving sheets. Its high sensitivity and quick response prevent false readings, even at high throughput speeds. The adjustable sensitivity buttons allow easy tuning for materials of different colors or reflectivity. By maintaining precise detection without mechanical adjustments, it ensures smoother cutting, folding, and stacking operations, enhancing overall production quality and reliability.
