The SICK WSE280-2N4331 through-beam photoelectric sensor is designed for applications that require accurate detection over extended distances. Using a strong red LED emitter and a receiver configured for high sensitivity, it delivers stable operation across spans up to 50 meters, with a maximum capability of 60 meters, as specified in the datasheet . Its fast switching response, rugged ABS housing, and dual environmental protection ratings (IP66/IP67) make it suitable for production lines, logistics paths, and outdoor handling systems. This model helps solve common challenges such as misalignment, low visibility, and fluctuating detection reliability in harsh industrial setups.
The WSE280-2N4331 uses a sender–receiver pair to maintain a clean optical signal, minimizing interference that often affects reflective systems. Its adjustable control, NPN switching output, and selectable operating mode support easy onsite configuration without complicated tools. The wide operating temperature range and durable optical components provide consistent results even where dust, vibration, or temperature variation are present. Thanks to its fast response time, it supports high-speed conveyors, packaging lines, and automated positioning tasks. Overall, it enhances throughput, reduces downtime, and ensures dependable detection in applications that require precision over long distances.

In modern logistics hubs, conveyor lines move items continuously and often span long distances, making reliable detection critical. The WSE280-2N4331 fits this environment because its through-beam design maintains a clear signal even when dust or packaging fragments accumulate in the air. Its long sensing capability allows sender and receiver units to be installed far apart without losing accuracy. With a rapid response time, the sensor quickly identifies items traveling at high speeds, helping automatic sorters and diverters react on time. This reduces slowdowns, minimizes manual checks, and supports consistent flow throughout the distribution process.
Automated palletizing systems rely on precise confirmation of pallet arrival, alignment, and departure. The WSE280-2N4331 proves useful here because its stable beam is less affected by glossy wrap films, pallet texture, or minor vibrations from conveyor rollers. Its long detection path enables sensors to be mounted at a distance from moving equipment, reducing the chance of accidental impacts. By providing consistent on/off signals, it allows control units to validate whether pallets are properly positioned before machinery shifts or rotates. This creates smoother operation, fewer stoppages, and a much lower risk of collisions inside automated material-handling zones.
Facilities that manage heavy vehicle traffic often need detection systems that remain reliable despite outdoor conditions. The WSE280-2N4331 supports this by using a dedicated emitter and receiver pair that maintains a strong optical path even when exposed to bright sunlight, dust, or moisture. Because the beam can cover wide entry lanes, vehicles are detected the moment they pass through the monitored zone. The rugged housing and environmental sealing ensure the sensor continues working during rain or temperature shifts. When integrated into access-control systems, it helps automate gate operations and improves monitoring accuracy around perimeter entry points.
Packaging machinery operates rapidly, and even a small obstruction can halt production. The WSE280-2N4331 is effective in these applications because its fast switching capability identifies any interruption to the beam almost immediately. This enables early detection of product buildup, misfed cartons, or film snags. The long-range operation allows the sensor pair to be mounted outside tight moving areas, keeping them protected while still achieving precise detection. Its consistent switching performance helps differentiate between normal mechanical cycles and actual blockages. As a result, operators experience fewer emergency stops, better equipment protection, and improved production continuity.
