The SICK WT24-2R210S03 (Part No. 1017856) is a versatile retro-reflective photoelectric sensor engineered for reliable detection of objects in medium-range industrial automation applications. With its visible red LED emitter, the sensor provides a detection range from 0.1 m up to 4 m when paired with a suitable reflector. This makes it an excellent choice for tasks such as conveyor monitoring, packaging automation, logistics handling, and general object presence verification.
One of the sensor’s key strengths is its fast response time and dependable switching behavior. Built for dynamic automation environments, the WT24-2R210S03 ensures accurate detection even when objects move quickly, have irregular shapes, or exhibit challenging surface reflectivity. Its short reaction time allows precise synchronization with high-speed processes, supporting smooth production flow while reducing detection errors and downtime.
The WT24-2R210S03 is designed with user-friendly setup and alignment in mind. A visible red light spot provides clear visual guidance during installation, simplifying alignment with the reflector and target objects. Combined with intuitive adjustment controls, operators can easily fine-tune the sensor’s detection range and sensitivity to suit specific applications. This flexibility makes the device particularly useful in production environments where frequent product or configuration changes require adaptable sensing solutions.
Durability is another defining feature of this model. The sensor’s rugged IP67-rated housing protects it from dust, moisture, and water spray, ensuring stable operation even in harsh industrial conditions. Its robust construction guarantees a long service life, minimizes maintenance needs, and supports reliable performance in demanding environments such as warehouses, manufacturing plants, and packaging facilities. The compact housing also allows installation in tight spaces without compromising function.
Integration into automation systems is straightforward with the PNP output interface, which ensures compatibility with programmable logic controllers (PLCs) and other industrial control systems. This makes the WT24-2R210S03 easy to incorporate into existing infrastructures while delivering dependable communication for process control.
In summary, the SICK WT24-2R210S03 combines retro-reflective detection, high-speed switching performance, ease of setup, and rugged construction to provide a robust sensing solution for industrial automation. Its 4 m sensing range, fast response time, and durable build make it a reliable choice for applications in logistics, packaging, and conveyor systems. By offering accurate detection, easy integration, and long-lasting durability, the WT24-2R210S03 supports improved efficiency, reduced downtime, and consistent quality in automated production environments.
