The Applications of SICK WF120-40B410 Fork Sensor
1. Precision Labeling in Beverage Production Lines
In automated labeling systems for bottles and cans, accuracy and timing are critical. The WF120-40B410’s infrared optical detection identifies even the thinnest or transparent labels moving at high speed. With its fast 10 kHz switching frequency and 0.2 mm sensitivity, it ensures every label is placed correctly, reducing waste and downtime. Its durable aluminum body withstands vibration and moisture common in beverage facilities, guaranteeing consistent performance throughout continuous shifts.
2. Edge and Cutout Detection in Flexible Packaging Films
When working with continuous rolls of packaging film, identifying perforations, edges, or gaps can be difficult. The WF120-40B410 precisely senses these transitions, even on glossy or semi-transparent materials. Its quick response time allows instant feedback for cutting or sealing operations. By detecting imperfections early, it prevents defective packaging from reaching final assembly, improving product consistency and reducing rework or scrap.
3. Transparent Bottle and Tube Level Verification
In cosmetic and pharmaceutical filling stations, the need to confirm the presence of liquid in clear containers is vital. The WF120-40B410 detects the optical difference between filled and empty containers without any physical contact. Its infrared beam remains stable despite reflections from curved surfaces, ensuring that underfilled or missing bottles are identified before capping. This enhances quality control and supports fast, automated inspection cycles.
4. Splice and Web Monitoring in Label Roll Changeovers
During high-speed label roll replacement, splice points must be detected to maintain alignment and prevent labeling errors. The WF120-40B410 instantly recognizes the small thickness variation when two label webs join. Its high switching frequency provides accurate timing, allowing machinery to adjust or pause automatically. This smooth changeover process keeps production continuous, prevents label misfeeds, and minimizes downtime during roll transitions.
