In high-speed packaging systems, products with shiny or transparent surfaces often cause false detections. The SICK WTF12-3N2441 overcomes this by using foreground suppression to focus precisely on the product’s surface, ignoring conveyor reflections. Its 1,500 Hz switching frequency enables accurate edge detection even when items move rapidly on the line. The robust IP69K metal housing ensures long-term reliability in environments exposed to cleaning agents or splashing water, helping maintain smooth packaging flow without sensor interference or downtime.
During vehicle assembly, sensors must confirm the presence of components before welding or painting. The WTF12-3N2441’s visible red LED beam and high response speed (≤330 µs) provide instant verification when parts are placed. Its rugged metal housing tolerates vibration and temperature variation commonly found in automotive plants. The sensor’s ability to detect dark or metallic surfaces ensures accurate placement verification, reducing the risk of defects and improving overall production quality and efficiency.
In logistics and warehouse automation, belts and trays often reflect ambient light or collect dust that disrupts standard sensors. The WTF12-3N2441’s foreground suppression eliminates these false triggers by isolating the moving object from its background. Its compact size allows easy integration on multi-level conveyors, and the M12 plug connection makes maintenance quick. This combination of precision and robustness enhances sorting accuracy, minimizes stoppages, and supports 24/7 operation in high-volume distribution centers.
Detecting edges of foil or transparent blister packs in pharmaceutical lines is challenging due to reflectivity and small tolerances. The WTF12-3N2441 delivers consistent detection with its tight light spot and adjustable sensitivity, ensuring precise alignment for sealing or cutting operations. Its washdown-proof housing withstands cleaning cycles in sterile rooms, while stable performance at varying distances supports continuous operation. This reliability helps pharmaceutical manufacturers maintain product integrity and reduce waste during high-speed production.
