The Applications
1. Clear Bottle Presence Verification on Beverage Filling Lines
In beverage production, clear PET or glass bottles move through filling stations at high speed, where accurate presence detection is essential. The SICK WL9G-3P1132 is applied to confirm each bottle is correctly positioned before filling and capping. Its coaxial optical design improves contrast on transparent surfaces, reducing missed detections caused by reflections or ambient light. The fast response supports rapid conveyor speeds, while automatic signal adaptation keeps detection stable despite splashes or dust. This prevents empty fills, reduces product waste, and protects downstream equipment from contamination.
2. Transparent Film Detection in Packaging Machines
Packaging machines that handle clear films often struggle with reliable material detection during feeding and sealing. In this application, the WL9G-3P1132 monitors transparent film movement to ensure correct alignment before sealing operations. The focused red light spot helps distinguish thin film edges from reflective rollers and metal frames. Stable detection reduces film misfeeds, seal defects, and material waste. Its compact housing fits easily into tight spaces near guide rollers, while the rugged enclosure supports continuous operation and routine washdowns. The result is improved packaging consistency and fewer unplanned machine stops.
3. Blister Pack Monitoring in Pharmaceutical Production
Blister packaging lines require precise monitoring to ensure each transparent cavity is formed and indexed correctly. The WL9G-3P1132 is used to detect the presence and movement of clear blister sheets between forming, filling, and sealing stages. Reliable detection helps prevent skipped doses, damaged packs, and costly rework. The sensor’s fast switching enables accurate synchronization with machine cycles, while its durable construction withstands frequent cleaning common in pharmaceutical environments. This application supports higher quality assurance, reduced scrap, and more stable production in regulated manufacturing settings.
4. Clear Tray Detection in Automated Intralogistics Systems
Automated intralogistics systems often use transparent trays or totes to transport goods between stations. Detecting these carriers at transfer points can be challenging due to their low visibility. The WL9G-3P1132 provides consistent detection to confirm tray arrival and correct positioning on conveyors or lifts. Its flexible sensing range allows practical mounting across wider gaps, while the robust design tolerates vibration and temperature variation. Accurate tray detection prevents collisions, ensures smooth handovers, and helps maintain reliable material flow in high-throughput warehouse operations.
