SICK WL24-2V230 Long-Range Photoelectric Retro Sensor

SICK WL24-2V230 Photoelectric Retro-Reflective Sensor – Long-Distance, Stable Object Detection

The SICK WL24-2V230 is a high-performance photoelectric retro-reflective sensor designed for applications that demand dependable long-range detection. Using a dual-lens optical system and a visible red LED, it achieves sensing distances of up to 22 meters while maintaining consistent performance even when dust, vibration, or changing lighting conditions are present. Built with a rugged metal housing and engineered for quick installation, the WL24-2V230 is well-suited for conveyors, automated handling equipment, and industrial machinery. Its adjustable sensitivity and clear visual indicators help technicians set up the device quickly and ensure stable detection throughout continuous operation.

Engineered for demanding environments, the WL24-2V230 offers fast response times and flexible switching options that make it highly adaptable to modern automation systems. Operators benefit from its ability to detect reflective targets reliably without being affected by shiny surfaces, thanks to its integrated polarization filter. The device’s robust enclosure and wide operating temperature range allow it to function outdoors or in harsh indoor settings. Maintenance teams also appreciate the intuitive signal strength indicators, which simplify fine-tuning and reduce troubleshooting downtime. Whether used in logistics, packaging, or manufacturing lines, this sensor delivers steady detection performance that helps keep processes moving efficiently and safely.

Why WL24-2V230?

The WL24-2V230 stands out because it delivers long-distance detection with impressive stability, even in environments that challenge typical photoelectric sensors. Its dual-lens design, rugged metal housing, and fast response make it ideal for operations that cannot afford unreliable sensing. It’s built for technicians who want a sensor that installs quickly, performs consistently, and withstands tough industrial conditions.

What problem does it solve?

The WL24-2V230 solves the challenge of detecting objects accurately over long ranges where dust, vibration, shiny surfaces, or changing light normally disrupt sensors. It ensures machines stay synchronized, conveyors run smoothly, and automated systems maintain efficiency. Wherever misdetection causes downtime or safety risks, this sensor eliminates uncertainty and brings stable, predictable performance.

Commercial Data – SICK WL24-2V230

The Applications 

1. High-Speed Conveyor Package Detection in Distribution Centers

Large parcel centers depend on conveyor systems that move items rapidly and unpredictably. The WL24-2V230 fits these fast-moving environments by maintaining stable detection even when packages vary in reflectiveness or sit at awkward angles. Its dual-lens optical setup reduces false triggers from glossy tape or loose wrapping, while the fast reaction time keeps pace with high-volume sorting. The visible red light spot helps technicians align the sensor quickly without stopping the line. With accurate object recognition over long distances, the conveyor control system stays synchronized, reducing misroutes and preventing blockages that slow down distribution operations.

2. Pallet Position Verification in Automated Warehouse Racking

In automated warehouses, storage robots rely on precise sensing to confirm whether a pallet is correctly positioned before executing movements. The WL24-2V230 supports this task by offering long-distance detection that remains stable despite dust, vibration, and shifting temperatures inside tall racking structures. Its metal housing withstands continuous industrial use, while the polarization filter minimizes interference from shiny wrapping film commonly found on pallets. By delivering consistent, repeatable detection, the sensor helps robotic shuttles and lifts avoid placement errors, keeps workflows streamlined, and reduces costly interruptions in large-scale storage operations.

3. Vehicle Monitoring at Industrial Access Points

Industrial entry zones often need a dependable method to sense incoming trucks and activate gates or safety barriers at the right moment. The WL24-2V230 provides long-range object detection that remains reliable outdoors, where lighting and weather conditions frequently change. Its strong housing resists dust, vibration, and temperature fluctuations, while the optical filter prevents false readings caused by reflective vehicle surfaces. With its fast switching speed, the sensor detects moving trucks without delay, making access control smoother and reducing the need for manual supervision. This supports safer, more predictable vehicle flow across busy industrial sites.

4. Film Roll Diameter Monitoring in Packaging Lines

Packaging machines rely on film rolls that unwind continuously, and identifying the right moment to replace a roll helps avoid production stops. The WL24-2V230 can monitor roll size by detecting the distance between the sensor and a reflector positioned behind the roll. Its rapid switching allows it to keep pace with high-speed unwinding, while adjustable sensitivity helps avoid false triggers caused by shiny film surfaces. With its long sensing range, the sensor can be mounted safely away from moving parts. This setup lets operators spot diminishing film rolls early, ensuring consistent machine performance and reducing unplanned downtime.
