Why WL11-2P2430S02?
The WL11-2P2430S02 is chosen when reliability matters more than assumptions. It is built for engineers who need stable, repeatable detection over long distances without constant recalibration. Its optical design, fast response, and rugged housing make it suitable for real factories, not just clean test benches. When production lines run continuously and downtime is costly, this sensor provides confidence that detection will remain accurate despite vibration, humidity, washdown, or reflective materials in the field.
What problem does it solve?
The WL11-2P2430S02 solves the common problem of unreliable object detection in harsh or complex environments. Conventional sensors often struggle with long distances, shiny surfaces, or contamination from water and dust, leading to false triggers or missed detections. This sensor delivers consistent performance where alignment tolerance, environmental sealing, and response speed are critical. It ensures stable presence detection and counting on conveyors, automated machines, and outdoor systems, reducing errors, downtime, and manual intervention.

The Applications of the WL11-2P2430S02
1. High-Speed Conveyor Presence Detection
In automated conveyor systems, products often travel at high speed and across long distances, making stable detection a constant challenge. The WL11-2P2430S02 is well suited for these conditions due to its long sensing capability and fast response time. The retro-reflective operating principle allows reliable detection regardless of product color variations. Its polarisation filter helps avoid false signals caused by glossy films or reflective packaging. Compact housing dimensions also allow installation in restricted conveyor frames, ensuring continuous monitoring of product flow while reducing unexpected line interruptions.
2. Packaging Line Product Counting and Verification
Packaging equipment depends on precise object detection to confirm product presence before sealing or labeling. The WL11-2P2430S02 delivers consistent counting performance through its stable optical system and rapid switching behavior. The visible red light simplifies alignment during commissioning, minimizing setup errors. Its resistance to vibration, dust, and ambient light fluctuations ensures dependable operation over long production cycles. By detecting each item accurately before downstream processes, the sensor helps prevent missing products, packaging errors, and costly production rework.
3. Washdown-Safe Detection in Food Processing Lines
Food processing environments expose sensors to water, cleaning chemicals, and temperature changes during frequent washdowns. The WL11-2P2430S02 is designed to operate reliably in these harsh conditions thanks to its sealed housing and high ingress protection. It is commonly used to detect trays, containers, or carriers moving between processing stages. The optical system maintains stable detection even when surfaces are wet or exposed to splashing, supporting hygienic operation while reducing sensor failures and unplanned maintenance.
4. Outdoor Logistics and Warehouse Gate Monitoring
Logistics yards and warehouse entrances require sensors that can perform consistently under varying weather and lighting conditions. The WL11-2P2430S02 is suitable for detecting pallets, containers, or vehicles passing through access points. Its long sensing distance allows flexible mounting away from traffic impact zones. The wide operating temperature range ensures reliable detection in both cold and hot environments. By maintaining stable performance despite dust, rain, and sunlight, the sensor supports reliable automation in outdoor material handling applications.
