In automated packaging operations, the SICK VL18-3F3740 ensures reliable detection of moving products such as cartons or pouches. Its fast 2 ms response allows accurate timing even on high-speed conveyors, while the polarizing filter minimizes false signals from glossy surfaces. The 3.7 m detection range provides flexibility for wider conveyors, and its M18 cylindrical body allows for quick installation in tight machinery layouts. These advantages help maintain synchronized movement, reduce line errors, and prevent production halts caused by undetected items.
In automated warehouses, pallets can vary in color, surface finish, or reflective wrapping—often causing detection issues. The VL18-3F3740’s retro-reflective sensing design maintains accuracy regardless of these variations. Its visible red LED beam simplifies alignment, while the IP67-rated enclosure ensures performance in dusty or humid environments. The sensor helps confirm pallet positions during transfer or stacking, improving logistics efficiency, reducing collisions, and ensuring uninterrupted warehouse operations.
For bottling or filling machines, the VL18-3F3740 provides dependable detection of transparent or shiny bottles without interference. The polarizing filter differentiates between reflective glass or PET surfaces, while sensitivity adjustment allows fine-tuning for different container types. Its compact M18 housing fits easily on high-density production lines. With consistent and rapid detection, manufacturers achieve accurate bottle counts, minimize product waste, and maintain smooth, continuous filling cycles.
In automated machinery, the VL18-3F3740 can be used for position sensing and object presence near moving components. Its fast switching response ensures immediate detection, enhancing operator safety and process control. The robust PBT/PC housing resists vibration and mechanical stress, making it ideal for tough production conditions. With long LED lifespan and low maintenance needs, the sensor supports reliable machine operation, reduces downtime, and contributes to a safer, more efficient working environment.
