The SICK WL24-2V240 (Part No. 1018024) is a versatile retro-reflective photoelectric sensor designed to provide reliable detection performance in a wide variety of industrial applications. With a visible red LED emitter and advanced optical filtering, this sensor ensures precise detection even in environments where shiny or reflective materials could otherwise cause interference.

One of the key advantages of the WL24-2V240 is its retro-reflective operating principle. By directing a visible red light beam toward a reflector, the sensor detects objects that interrupt the returning light. This allows for a long sensing range of up to 7 meters, making it ideal for material handling systems, conveyor monitoring, and packaging processes. The visible red beam also makes installation and alignment straightforward for operators.

Equipped with a polarization filter, the WL24-2V240 is capable of distinguishing between the intended reflected signal and stray reflections from shiny or mirrored surfaces. This ensures reliable detection of objects such as glossy packaging, metallic components, or films, where ordinary retro-reflective sensors may produce false triggers.

For system integration, the sensor includes a PNP transistor output with configurable light-ON and dark-ON modes. This output flexibility allows seamless connection to programmable logic controllers (PLCs) and other control devices, simplifying installation in diverse automation setups. By offering both operating modes, the WL24-2V240 adapts easily to application-specific logic without requiring additional wiring changes.

Durability and robustness are hallmarks of the WL24-2V240. Its IP67 and IP69K-rated housing protects it against dust, water ingress, and even high-pressure washdowns, making it well suited for use in harsh industrial environments such as food and beverage production or outdoor logistics systems. The housing is compact yet rugged, ensuring long service life while allowing installation in space-constrained applications. A standard M12, 4-pin connector guarantees secure electrical connections and supports rapid replacement during maintenance.

Performance is further enhanced by the sensor’s fast response time and consistent switching accuracy. This makes it suitable for detecting objects on fast-moving conveyors or in high-throughput packaging lines, where reliability is essential to avoid bottlenecks or downtime. Operators can also adjust the sensor’s sensitivity to match application requirements, ensuring stable detection across a variety of object sizes, colors, and surface finishes.

In summary, the SICK WL24-2V240 combines long-range retro-reflective detection, advanced filtering, flexible output options, and rugged construction. It is an excellent choice for engineers seeking a dependable and adaptable sensor that can handle reflective surfaces, withstand demanding environments, and integrate easily into modern automation systems.
