The Applications of SICK WT24-2B250 Photoelectric Sensor
1. Precision Detection in Metal Sheet Processing
In sheet-metal fabrication lines, the WT24-2B250 ensures accurate detection of metal sheets despite shiny or uneven surfaces. Its background suppression eliminates false readings from reflective machinery or lighting. With a sensing range up to 1,200 mm, the sensor can reliably identify edges and gaps for positioning or cutting control. The IP67 zinc die-cast housing resists metal dust and oil spray, keeping the system stable under heavy vibration and heat from surrounding equipment.
2. Automated Packaging and Conveyor Systems
In automated packaging lines, the WT24-2B250 detects products of different shapes, materials, and colors on high-speed conveyors. Its light/dark mode selection helps differentiate objects from the moving belt, ensuring every item is counted or verified before sealing. The integrated lens heater prevents condensation in humid environments, maintaining precision where temperature changes are frequent, such as in chilled food or beverage packaging operations.
3. Positioning Control in Metal Coil Handling
During coil transport and unwinding operations, accurate alignment is crucial. The WT24-2B250 provides consistent detection of coil ends or edges even when surrounded by reflective steel. Its fast 500 µs response time captures rapid motion, while the robust metal housing withstands vibration and heavy mechanical stress. This allows smoother transitions between processing stages and minimizes misalignment, improving overall production efficiency.
4. Pallet and Object Detection in Automated Warehouses
In warehouse automation and AGV (Automated Guided Vehicle) systems, the WT24-2B250 is ideal for sensing pallet positions or confirming product presence on storage racks. The adjustable sensing range ignores fixed backgrounds while focusing on moving goods, preventing false triggers from reflective packaging. Its 1 kHz switching frequency supports real-time control, enabling reliable logistics tracking and optimizing warehouse throughput.
