The Applications

1. Flap Detection in High-Speed Cartoning Lines

In automated packaging systems, carton flaps must be perfectly folded before sealing. The SICK GTB6-P4241 detects each flap accurately using its infrared LED and background suppression, ensuring precise recognition even when box materials vary in color or reflectivity. Its <1 ms response time allows it to keep pace with fast-moving conveyors, preventing sealing errors and production slowdowns. Compact dimensions make it easy to install near the flap-folding area, enhancing overall packaging reliability.

2. Clear Bottle Detection on Filling Lines

Transparent PET bottles often cause false readings with conventional optical sensors. The GTB6-P4241 solves this by using infrared light and a focused 8 mm beam that distinguishes bottles from their reflective surroundings. It detects the presence or absence of clear bottles before filling or capping, maintaining synchronized operations. Its high switching frequency ensures smooth throughput on rapid production lines, reducing spillage and ensuring consistent product flow in beverage and cosmetics manufacturing.

3. Component Placement Check on PCB Trays

During electronic assembly, PCBs with dark coatings placed on black trays can challenge standard sensors. The GTB6-P4241 easily identifies the position of each board thanks to its precise background suppression and adjustable sensitivity control. Mounted on robotic or pick-and-place stations, it ensures components are present before assembly begins. This improves accuracy, avoids misalignment, and reduces waste from misplaced components—all within compact spaces where precise optical sensing is crucial.

4. Jam and Overflow Detection in Conveyor Systems

In logistics and warehouse automation, parcels or bins can pile up on conveyors. The GTB6-P4241 detects these blockages quickly using its wide sensing range of up to 450 mm and fast reaction time. By monitoring item presence at transfer points, it prevents system jams and stops conveyors before mechanical damage occurs. The IP67-rated housing resists dust and vibration, ensuring long-term reliability even in heavy-duty sorting or packaging environments.
