With easy alignment and adjustable sensitivity, this sensor ensures stable and dependable operation across a wide variety of applications.
The SICK WSE280-2H4331 is engineered for operations that rely on consistent detection accuracy across long production spans or wide machine layouts. Its dedicated emitter–receiver setup ensures strong optical clarity, enabling reliable switching even when positioned far apart. Fast response, relay-based output, and electrical noise suppression support steady integration into industrial control systems. The durable housing and stable optical components reduce signal loss caused by contamination or temperature changes, helping maintain uninterrupted workflow. Whether used in material handling, automated conveyors, or safeguarding tasks, this sensor enhances operational reliability while minimizing adjustments and downtime.
The SICK WSE280-2H4331 stands out because it delivers unwavering long-range detection that stays stable even when the environment doesn’t. It’s built for tough industrial realities—dust, vibration, temperature swings—and still performs with remarkable consistency. With its robust design, wide voltage compatibility, and precise through-beam optics, it becomes a “fit-and-forget” sensor that keeps your process flowing smoothly.
The WSE280-2H4331 solves the challenge of unreliable detection over long distances, especially where harsh conditions normally disrupt optical sensors. It eliminates false triggering, misreads, and alignment headaches across wide conveyor paths, tall machinery frames, or outdoor zones. By ensuring consistent signal strength and stable switching, it prevents downtime, improves process accuracy, and keeps operations running without interruption.

Large distribution halls often require sensors to monitor items over extended conveyor paths, where dust, vibration, and ambient lighting can disrupt normal detection. The WSE280-2H4331 excels because its strong through-beam design maintains a stable signal even when the sender and receiver are positioned far apart. Workers can align the beam easily using its visible red light, ensuring accurate detection of parcels of varying sizes. The sensor’s quick response helps prevent bottlenecks by identifying slow or stalled items instantly. Even as dust accumulates in busy sorting areas, the adjustable sensitivity keeps the detection zone clean, improving flow efficiency and reducing manual checks.
At busy loading docks, identifying when a truck approaches or aligns correctly can be difficult due to changing weather, engine fumes, and bright sunlight. The WSE280-2H4331 tackles these challenges by projecting a strong optical signal capable of cutting through environmental interference while remaining precise over long distances. Its durable enclosure handles outdoor dust and moisture without performance drop. Facilities can position the sensor to detect a vehicle’s presence before it reaches the dock, helping staff prepare equipment earlier and reducing the risk of collision. This provides a smoother loading sequence, improves timing, and enhances overall safety during peak operating hours.
Overhead cranes move across long horizontal tracks, and accurate end-position detection is essential to avoid overshoot and unnecessary strain on the system. The WSE280-2H4331 offers a clear advantage because its long optical range ensures the crane’s travel is monitored reliably from one end to the other. The sensor withstands vibration, temperature changes, and dust typically found near elevated metal structures. With its relay output, it integrates easily into older crane control circuits. By providing consistent detection even in dim or dusty upper areas of a warehouse, the sensor supports smooth braking sequences, reduces wear on motors, and enhances equipment longevity.
High-bay warehouse lanes are long, narrow, and filled with shadows, making consistent pallet detection challenging. The WSE280-2H4331 addresses this by creating a strong, uninterrupted beam that isn’t affected by reflections or shifting ambient conditions. Its long sensing range makes it suitable for deep storage lanes, where early detection of pallet movement can prevent jams and misalignment. The sensor’s sensitivity adjustment allows operators to fine-tune performance for various pallet materials and shapes. Even with dust generated by forklifts and packaging, the sealed housing protects the optical components, ensuring reliable performance. This leads to improved stock movement accuracy and smoother warehouse operations.
