The SICK WL24-2V540 (Part No. 1018025) is a retro-reflective photoelectric sensor designed to deliver robust and precise detection performance in demanding industrial environments. With a powerful visible red LED emitter and extended sensing capabilities, this sensor offers dependable operation for applications requiring medium- to long-range object detection.

At its core, the WL24-2V540 uses a retro-reflective principle. The sensor projects a visible red beam toward a reflector, and detection occurs when an object interrupts the returning light. This enables a long sensing distance of up to 17 meters, making it suitable for monitoring wide conveyor belts, large packaging operations, and logistics systems where long-range coverage is required. The clearly visible red light also simplifies sensor alignment during setup and maintenance.

The inclusion of a polarization filter ensures reliable detection even in challenging conditions where objects have reflective or shiny surfaces. This feature prevents false switching by blocking stray reflections, making the WL24-2V540 especially valuable in industries handling metallic packaging, glossy films, or reflective product materials.

For integration into control systems, the sensor is equipped with a PNP transistor output that can be configured for either light-ON or dark-ON operation. This versatility allows seamless adaptation to diverse automation requirements without additional hardware. By supporting both switching modes, it can easily fit into new or existing PLC-controlled processes.

The WL24-2V540 is also engineered to withstand harsh environments. Its rugged housing carries IP67 and IP69K protection ratings, ensuring resistance against dust ingress, water exposure, and even high-pressure cleaning. This makes the sensor suitable for industries such as food and beverage, automotive manufacturing, and material handling, where tough conditions demand durable equipment. The sensor’s M12, 4-pin male connector supports secure wiring and quick installation, further reducing downtime during maintenance or replacement.

In terms of performance, the WL24-2V540 provides fast and consistent response times, making it suitable for detecting objects moving at high speeds. Combined with its long sensing distance, it ensures accurate and stable performance across a wide range of operating conditions. Operators can fine-tune detection using the built-in adjustment mechanism, allowing the sensor to adapt to different target sizes, shapes, and reflectivity levels.

In summary, the SICK WL24-2V540 combines long-range retro-reflective detection, polarization filtering, flexible outputs, and rugged housing protection in a compact and reliable package. It is an excellent choice for automation tasks that demand precise detection, high durability, and seamless integration into industrial environments.
