The Applications
1. High-Speed Conveyor Product Detection
In automated conveyor lines, accurate detection at high speed is essential to prevent missed products and system interruptions. The SICK GRSE18-P1127 is effective in this environment because its through-beam sensing principle does not rely on reflected light from the object itself. This allows stable detection of dark, glossy, or unevenly shaped items. Its fast response time supports rapid movement without signal delay, while the long sensing range enables flexible sensor placement across wide conveyor frames. The compact M18 housing also allows installation in confined mechanical spaces commonly found in high-density production lines.
2. Pallet and Carton Presence Control in Warehouses
Automated warehouses require dependable presence detection to control pallet movement and ensure safe material handling. The SICK GRSE18-P1127 can monitor large cartons or pallets across long distances between conveyor lanes or storage racks. Infrared through-beam technology maintains consistent performance despite dust, worn packaging, or variable ambient lighting. The sealed housing protects the sensor from moisture and debris commonly found in logistics environments. By delivering clear on/off signals to control systems, the sensor helps reduce collision risks, improve positioning accuracy, and support smooth operation of automated storage and retrieval systems.
3. Transparent Container Detection on Filling Lines
Production lines handling bottles and containers often face detection challenges when products are transparent or highly reflective. The SICK GRSE18-P1127 overcomes this by interrupting a continuous infrared beam rather than depending on surface reflection. This allows reliable detection of glass and clear plastic containers before filling or capping stages. Its rapid switching capability ensures precise timing at high line speeds, reducing spillage and misfills. Adjustable sensitivity enables accurate alignment during setup, helping manufacturers maintain stable production and consistent quality in beverage, chemical, and pharmaceutical processing environments.
4. Component Counting and Position Verification in Assembly Cells
In automated assembly operations, precise component counting and position confirmation are critical for maintaining product quality. The SICK GRSE18-P1127 supports these requirements by reliably detecting parts as they move between stations. Its through-beam design ensures consistent sensing of small or irregular components that may be difficult for reflective sensors. Fast signal response allows accurate counting in rapid pick-and-place systems. Combined with protected electronics and stable output behavior, the sensor helps reduce assembly errors, supports repeatable automation, and improves overall efficiency in manufacturing and electronics assembly lines.
