SICK WT24-2B440 photoelectric sensor with background suppression for reliable object detection up to 1200 mm in harsh industrial environments.
The SICK WT24-2B440 photoelectric sensor with background suppression is a compact and rugged proximity sensor engineered for accurate object detection in industrial automation. It is designed to eliminate false triggering caused by reflective surfaces or distant backgrounds, ensuring consistent switching behavior. With a sensing distance of up to 1,200 mm and a clearly visible red LED light source, the WT24-2B440 delivers reliable performance across a wide range of object colors and surface finishes. Its durable metal housing and high enclosure rating make it suitable for harsh environments where reliability and stable detection are critical.
The WT24-2B440 improves process stability by reliably distinguishing target objects from backgrounds, even in applications with shiny materials or changing distances. Its fast response supports high-speed material flow, helping prevent missed detections on conveyors or automated handling systems. Flexible output configuration simplifies electrical integration, reducing commissioning effort during machine build or retrofit. The robust mechanical design withstands vibration, washdown, and temperature variations, minimizing unplanned downtime. As a result, operators benefit from higher system availability, consistent quality control, and reduced maintenance effort over the sensor’s operating life.
The SICK WT24-2B440 is chosen when detection reliability must remain consistent despite changing backgrounds, object colors, or harsh environments. Its background suppression technology delivers stable switching even in visually complex scenes, while the rugged metal housing supports long-term use in washdown and heavy-duty applications. Fast response, flexible output selection, and compact construction make it a dependable choice for machine builders who prioritize uptime, precision, and straightforward integration.
The WT24-2B440 solves the persistent issue of false detections caused by reflective surfaces, distant backgrounds, or mixed material finishes. In automated systems where accuracy directly impacts productivity, unreliable sensing leads to errors, stoppages, and quality losses. By clearly separating the target object from its background, this sensor ensures dependable detection at speed, stabilizing processes, reducing rejects, and maintaining smooth operation in demanding industrial environments.

In automated conveying systems, products often move rapidly against rollers, frames, or guide rails that can interfere with standard sensors. The WT24-2B440 is effective in these environments because it focuses only on the target object while ignoring the background structure. Even when items differ in color, size, or surface finish, detection remains consistent. The fast response time supports continuous flow without missed signals, while the visible red light simplifies setup and alignment. This results in accurate counting, smoother material handling, and fewer process interruptions.
Packaging equipment relies on accurate detection of products at specific positions to prevent sealing errors and mechanical jams. The WT24-2B440 performs reliably in machines with reflective metal components and limited installation space. Its background suppression prevents false triggering from machine parts, while the stable sensing range maintains consistent detection despite changes in packaging material. This allows the machine to operate at higher speeds with reduced setup effort, improving overall efficiency and reducing waste during frequent product changeovers.
In production zones that undergo regular cleaning, sensors must withstand moisture, chemicals, and temperature changes. The WT24-2B440 is well suited for these conditions due to its durable housing and high protection level. It continues to detect containers, carriers, or crates accurately even after repeated washdowns. Background suppression helps maintain stable performance when water residue or reflective surfaces are present, ensuring reliable operation. This reduces downtime, supports hygiene requirements, and lowers maintenance demands in food and beverage processing environments.
Automated assembly cells often require confirmation that components are correctly placed before the next operation begins. The WT24-2B440 enables dependable presence detection even when fixtures, tooling, or robotic elements are located behind the part. Its quick switching behavior supports short cycle times, while flexible output options ease integration with existing control systems. By ensuring accurate detection of components with varying surface finishes, the sensor helps prevent assembly errors, protects equipment, and maintains consistent production quality.
