The Applications – Real Industrial Use Cases of SICK GL6-P1112

1. Bottle Positioning on Beverage Conveyor Lines

In beverage plants, bottles made from glass or PET often confuse standard sensors due to reflections and transparency. The GL6-P1112 overcomes this with its polarized dual-lens system, allowing accurate detection of clear or shiny bottles on high-speed conveyors. The visible red LED ensures easy alignment even in tight spaces. Its IP67 housing protects against water and cleaning chemicals used in washdown zones. By providing stable, error-free detection, this sensor keeps bottling operations running smoothly and prevents line interruptions caused by misfeeds or missed bottle detection.

2. Component Verification in Robotic Assembly

During automated assembly, robots rely on sensors to confirm parts are correctly positioned before gripping. The GL6-P1112 delivers reliable part verification even with reflective metal or plastic components. Its fast 625 µs response time supports quick pick-and-place cycles, while the PNP output and polarity protection make integration simple. Compact in size, it fits easily into confined robotic cells. This precision reduces assembly errors and prevents costly rework, ensuring the robot only handles correctly positioned components with consistent timing accuracy.

3. Label Alignment in Packaging Systems

Accurate label placement depends on precise edge detection of packages moving through labeling machines. The GL6-P1112 maintains steady performance with variable materials such as glossy cartons, plastic wraps, or foil packaging. Its visible red LED and light/dark mode selection allow quick setup for each packaging line. The sensor’s stainless steel mounting bracket ensures stable installation even in high-vibration environments. This reliability helps reduce label waste, prevents skewed applications, and increases labeling machine throughput across continuous production runs.

4. Entry and Object Detection for Access Gates

In automated doors or guarded work areas, consistent detection is essential for safety. The GL6-P1112 provides a compact and robust solution for monitoring objects or people entering restricted zones. Its focused red beam accurately detects small or irregularly shaped objects, while the sealed IP67 enclosure resists dust and humidity in industrial or outdoor settings. The high-speed response minimizes false triggers and enhances safety performance, ensuring access systems respond quickly and precisely under all environmental conditions.
