In beverage and bottling plants, sensors must detect clear or tinted bottles moving at high speed without interference from reflections or liquid surfaces. The WTB11-2P2461 excels by using precise background suppression to ignore shiny conveyors and detect bottles consistently. Its PinPoint LED creates a focused light spot for stable recognition even through transparent materials. With a 2.5 ms response time, it ensures every bottle is identified accurately, reducing line stoppages and improving overall production flow.
Warehouses and courier systems handle packages of various colors, materials, and surface finishes. The WTB11-2P2461 maintains reliable detection regardless of box tone or reflectivity. Its stable sensing range prevents false readings caused by conveyor belts or bright plastic wrapping. This ensures accurate item counting, tracking, and sorting in high-speed parcel systems. As a result, operations run smoother, minimizing mis-sorts and improving overall logistic efficiency.
Automotive production involves inspecting items like dark rubber seals, glossy trim pieces, or transparent hoses, which can confuse conventional sensors. The WTB11-2P2461 overcomes this challenge with PinPoint LED technology that provides a concentrated detection spot and background suppression that filters unwanted reflections. This allows accurate part verification across different surface types, ensuring high-quality assembly and reducing costly rework or production delays.
In food manufacturing areas, sensors often face humidity, cleaning sprays, and temperature fluctuations. The WTB11-2P2461, built with IP69K-rated protection, resists water and chemical exposure during wash-down cycles. It avoids detection errors caused by moisture or droplets reflecting light on metal surfaces. This reliability keeps conveyor systems running even during cleaning processes, ensuring compliance with hygiene standards while maintaining steady production throughput.
