The Applications

1. Automated Storage & Retrieval Systems

In large warehouse environments, objects such as cartons or bins move rapidly across conveyors or lift systems. The WTB26I-24161420A00 excels in this scenario due to its 3,000 mm sensing range and precise background suppression, ensuring the sensor focuses only on the target item and not the rack or background. Its infrared LED beam remains stable even when scanning dark, glossy, or metallic packages. By using IO-Link connectivity, operators gain instant feedback and easy integration with warehouse control systems, improving flow efficiency and reducing false triggers during continuous operation.

2. High-Speed Packaging Line Inspection

On fast-moving packaging machines, reflective films and bright surfaces can cause false readings. The BluePilot Teach-Turn adjustment on the WTB26I-24161420A00 allows technicians to fine-tune detection distance within seconds, ensuring accurate presence verification even for transparent or shiny materials. With a switching frequency up to 200 Hz, the sensor keeps up with high throughput lines. Built-in logic functions such as delay timers and window detection simplify control tasks without extra devices, enhancing precision and reducing setup time across multiple packaging stations.

3. Robotic Assembly and Gripper Feedback

In automated assembly cells, robot grippers must detect small or irregular components before handling them. The WTB26I-24161420A00 provides stable detection regardless of material or finish, whether matte plastic or polished metal. Its dual PNP/NPN outputs and compact VISTAL® housing make it easy to mount on moving parts without adding weight. With IO-Link diagnostics, operators can monitor detection quality and alignment in real time, helping robots operate faster with fewer mis-picks or alignment errors—essential in precision-driven industries like automotive and electronics.

4. Pallet and Container Detection for Mobile Platforms

Automated guided vehicles and robotic shuttles rely on accurate object recognition while operating in varying light conditions. The IP69-rated WTB26I-24161420A00 is built for such demanding tasks, enduring vibration, dust, and frequent cleaning. Its infrared optical system maintains consistent readings outdoors or in dimly lit areas. The sensor easily detects pallets and containers even when surfaces are uneven or wet. Through real-time IO-Link data, maintenance teams can track sensor health and adjust performance remotely, ensuring uninterrupted logistics flow and minimal downtime.
