SICK WL24-2V540 Retro-Reflective Photoelectric Sensor

SICK WL24-2V540 Retro-Reflective Photoelectric Sensor with IP69K Protection

The SICK WL24-2V540 retro-reflective photoelectric sensor is designed for dependable object detection in harsh industrial environments where dirt, moisture, and long sensing distances can compromise standard sensors. Using a dual-lens optical design, it provides stable detection performance over extended ranges while maintaining precise switching behavior. Its robust metal housing and high ingress protection make it suitable for washdown areas and outdoor installations. The sensor addresses common issues such as signal instability and environmental interference, delivering reliable detection for automated machinery, conveyor systems, and production lines.

In practical industrial use, the SICK WL24-2V540 helps reduce unplanned downtime caused by unreliable sensing. The integrated polarisation concept improves detection consistency when monitoring reflective or glossy objects, while the heated front screen supports operation in cold or humid conditions. Adjustable time delay functions smooth signal output on fast-moving or uneven products, improving process stability. Flexible output configuration allows easy integration into different control systems, making this sensor a strong choice for facilities that demand durability, accuracy, and long-term operational reliability.

Why SICK WL24-2V540?

The SICK WL24-2V540 is chosen when reliability cannot be compromised in tough industrial environments. It combines long sensing distance with stable retro-reflective detection, making it suitable for large machines, conveyors, and logistics systems. Its rugged metal housing and high protection rating support continuous operation under washdown, dust, and vibration. Advanced optical design and flexible signal configuration allow it to adapt easily to different products, speeds, and control systems, reducing setup time while delivering consistent, repeatable detection performance.

What problem does it solve?

The SICK WL24-2V540 solves the challenge of unreliable object detection in environments where moisture, dirt, reflections, or temperature changes cause frequent sensor failures. Standard sensors may misread shiny surfaces, fog up, or drift over time, leading to false signals and production stops. This model maintains detection accuracy over long distances and harsh conditions, stabilizing sensor output and minimizing false triggering. As a result, it helps protect process continuity, improves machine uptime, and reduces maintenance effort.

The Applications for SICK WL24-2V540

1. Stable Pallet Detection in Automated Warehousing

In automated storage and retrieval systems, pallet detection must remain accurate despite dust, vibration, and long conveyor distances. The SICK WL24-2V540 is commonly installed at transfer points to confirm pallet presence before sorting or stacking. Its long sensing distance allows flexible mounting away from mechanical wear zones. Retro-reflective sensing ensures reliable detection regardless of pallet color, while the polarisation feature helps avoid false signals from stretch wrap. Adjustable delay settings stabilize output during pallet movement, supporting smooth conveyor operation and reducing unplanned stops in high-throughput warehouse environments.

2. Bottle Verification on Beverage Filling Lines

High-speed beverage filling lines require precise bottle detection under constant washdown conditions. The SICK WL24-2V540 is used before filling heads to verify container presence and positioning. Its robust housing tolerates frequent high-pressure cleaning, while the heated front optics reduce condensation during temperature changes. Fast response time supports rapid bottle flow without missed detections. Flexible output configuration simplifies integration with existing control logic. This reliable detection helps prevent misfilling, reduces waste, and maintains consistent production performance in demanding beverage processing environments.

3. Outdoor Cargo Detection at Logistics Loading Bays

Outdoor logistics facilities expose sensors to rain, dust, vibration, and temperature extremes. The SICK WL24-2V540 is applied at loading bay entrances to detect trucks, containers, or moving cargo. The visible red light aids alignment across wide gate openings, while the metal housing resists mechanical stress. Its wide operating temperature range supports continuous operation throughout the year. Consistent retro-reflective detection ensures dependable signals even when cargo surfaces vary, enabling accurate control of gates, warning systems, and automated safety functions.

4. Part Presence Monitoring in Metal Processing Automation

Metalworking environments challenge sensors with reflective surfaces, oil mist, and airborne particles. The SICK WL24-2V540 is used to confirm part presence before machining or robotic handling steps. The polarisation design minimizes interference from shiny metal components, improving detection stability. Sensitivity adjustment and delay functions allow tuning for irregular shapes or variable feed speeds. With fast switching and protected outputs, the sensor supports reliable automation cycles, reduces false rejects, and helps maintain consistent quality in demanding metal processing lines.
