The Applications
1. High-Speed Parcel Detection in Conveyor Systems
In modern logistics hubs, parcels of different sizes and colors move rapidly along conveyors. The WTB16I-1H162120A00 ensures each package is detected accurately without being affected by reflective roller surfaces or ambient light. Its background suppression feature prevents false readings, while the 1,000 Hz switching frequency handles fast-moving boxes efficiently. By maintaining consistent detection even under vibration or dust, it minimizes jam incidents and enhances overall sorting reliability.
2. Carton Height Verification in Packaging Lines
During secondary packaging, overfilled or uneven cartons can lead to sealing defects. This sensor, mounted above the conveyor, detects precise object height and identifies any irregular layers. The BluePilot Teach-Turn adjustment allows quick recalibration for different packaging types, while the infrared LED beam remains unaffected by glossy or dark surfaces. As a result, manufacturers achieve better quality control, reduced rejects, and faster changeovers between product runs.
3. Small Part Detection in Automated Assembly
On assembly lines where dark or shiny components are handled, standard sensors often struggle to differentiate between the object and its background. The WTB16I’s advanced background suppression and narrow light spot enable accurate detection of small items, even against complex or reflective surfaces. Its IO-Link communication ensures precise monitoring and real-time feedback, improving production accuracy and helping prevent missing or misaligned parts during assembly operations.
4. Rapid Changeover in Food and Packaging Machines
In production environments that handle multiple packaging formats, frequent sensor adjustments can slow down operations. The WTB16I-1H162120A00 solves this through IO-Link-based configuration, allowing operators to remotely modify sensing parameters and check signal strength. Its rugged VISTAL® housing and IP69 protection rating resist cleaning agents and moisture, making it ideal for hygienic applications. This flexibility cuts downtime during product changeovers and supports predictive maintenance planning.
