The Applications
1. High-Speed Conveyor Object Monitoring
In fast-moving conveyor systems used for sorting and packaging, accurate object detection is essential to maintain flow and avoid product collisions. The SICK VTE18-3F4740 fits easily into narrow conveyor frames thanks to its M18 cylindrical housing. Its rapid response time allows it to detect products moving at high speeds without signal delay. The adjustable sensing range helps operators optimize detection for different product sizes, while infrared energetic sensing maintains stable performance regardless of box color or surface finish. This combination reduces false triggers, improves throughput, and minimizes unexpected conveyor stoppages.
2. Component Presence Verification in Automated Assembly
Automated assembly machines often need to confirm that a component is present and correctly positioned before the next operation begins. The SICK VTE18-3F4740 enables reliable non-contact detection, eliminating wear issues associated with mechanical switches. Its infrared sensing reliably detects parts with mixed materials and inconsistent reflectivity. The fast switching behavior supports short cycle times, while the sealed housing protects against dust and oil exposure. This ensures stable process control, prevents incomplete assemblies, and helps maintain consistent product quality over long production runs.
3. Container Detection in Packaging and Filling Equipment
Packaging and filling equipment relies on accurate presence detection to avoid spills, misfills, or labeling errors. The SICK VTE18-3F4740 is well suited for detecting containers, cartons, or trays as they move through packaging stations. Sensitivity adjustment allows reliable detection of transparent, dark, or irregular packaging shapes. Its compact form simplifies integration near moving machine parts, and its fast response supports rapid indexing. These features help reduce waste, improve machine uptime, and ensure smooth operation in high-volume packaging environments.
4. Position Feedback in Material Handling Systems
Material handling equipment such as transfer units, lifts, and automated shuttles requires dependable position feedback for safe motion control. The SICK VTE18-3F4740 can be used to detect carrier positions, pallet edges, or mechanical reference points. Infrared energetic sensing ensures consistent detection even in dusty or variable lighting conditions. The rugged construction supports continuous operation across a wide temperature range. By providing accurate position signals, the sensor helps improve system coordination, reduce mechanical stress, and support reliable automation in demanding industrial settings.
