The Applications of SICK WTB11-2P2431 Photoelectric Sensor
1. High-Speed Conveyor Package Counting
In fast-moving logistics centers, conveyors handle parcels of different sizes, materials, and surface finishes. The WTB11-2P2431 accurately detects each package regardless of reflective or dark wrapping. Its background suppression capability filters out reflections from the belt surface, ensuring every item is registered correctly. The fast 2.5 ms response time prevents missed counts on high-speed lines, while the visible red light simplifies setup and maintenance. This ensures seamless sorting and improved throughput in automated warehouse systems.
2. Bottle Detection on Beverage Filling Lines
Beverage filling systems require precise detection as bottles of varying transparency and shapes move quickly through rinsing and capping stages. The WTB11-2P2431 reliably senses both clear and opaque bottles, unaffected by water, steam, or stainless-steel reflections. Its IP69K-rated housing withstands regular washdowns and cleaning agents, keeping production continuous. The fast switching capability ensures bottles are consistently identified, reducing filling errors and line stoppages for more efficient packaging output.
3. Robotic Assembly Verification
In automated assembly cells, robotic arms must confirm the presence of small or irregular components before placement. The WTB11-2P2431 provides stable detection even when parts have glossy, dark, or metallic surfaces. Its compact ABS housing fits easily near grippers or jigs, while the adjustable potentiometer fine-tunes detection distance for each task. This sensor minimizes false readings, prevents assembly mistakes, and supports quality control for high-precision electronic or mechanical manufacturing lines.
4. Pallet and Stack Height Control
During packaging and palletizing, maintaining uniform stack height is crucial to prevent damage during wrapping or transport. The WTB11-2P2431 detects the top layer of stacked boxes with precision, ignoring shiny film or background variations. Its 350 mm sensing range accommodates tall or uneven loads, ensuring accurate monitoring before wrapping or labeling. This enhances automation efficiency, reduces manual checks, and ensures every pallet is correctly prepared for shipment.
