The Applications of SICK WL8G-P2231S01 Photoelectric Sensor

1. Transparent Bottle Detection in Beverage Filling Lines
In beverage production, transparent bottles can be difficult to detect due to reflections from curves or condensation. The WL8G-P2231S01 overcomes this challenge through coaxial optics and polarized light that clearly identify bottles, even when they’re glossy or wet. Its rapid 0.5 ms response supports continuous motion on high-speed conveyors, ensuring precise timing for filling and capping. This reliable detection reduces stoppages, prevents misalignment, and keeps production lines running efficiently without product loss.

2. Film and Sheet Positioning in Packaging Systems
Thin transparent films often confuse standard sensors during wrapping or sealing. The WL8G-P2231S01 detects clear plastic layers consistently, avoiding false triggers from machine reflections. With adjustable sensitivity control, it adapts to multiple film types and thicknesses. When installed near sealing jaws or rollers, it ensures accurate positioning and cutting, minimizing waste and downtime. This precise film detection contributes to better packaging integrity and smoother operation in automated lines.

3. Glass Vial Detection in Pharmaceutical Production
Detecting clear glass vials on inspection or filling conveyors is critical for pharmaceutical accuracy. The WL8G-P2231S01 uses a fine light beam to identify vials regardless of transparency or curvature. Its compact design allows easy integration into small machinery and clean environments. Resistant to vibration and dust, it maintains stable operation, preventing skipped or double detections. This ensures consistent vial handling, improved safety, and compliance with high pharmaceutical quality standards.

4. Container Recognition in Food Packaging Lines
Food processing lines require dependable detection of transparent or semi-clear containers for accurate portioning and sealing. The WL8G-P2231S01 delivers precise results even when trays are wet or glossy. Its IP67-rated housing withstands moisture and cleaning cycles common in food factories. Fast switching capability enables reliable product tracking at high speeds. This results in fewer packaging errors, optimized throughput, and consistent quality across automated food packaging systems.
