SICK WS/WE100L-E2131 laser through-beam photoelectric sensor for precise long-range detection of small, fast-moving objects in industrial automation.
The SICK WS/WE100L-E2131 W100 Laser through-beam photoelectric sensor is a compact industrial sensing solution engineered for precise object detection over long distances. It is designed to solve detection challenges involving very small parts, narrow edges, or rapidly moving objects where standard photoelectric sensors may fail. By using a visible red Class 1 laser and a tightly focused beam, this sensor maintains stable alignment and accurate switching performance up to 30 meters. Its slim W100 housing allows seamless integration into space-limited machinery while supporting reliable operation in continuous production environments.
The SICK WS/WE100L-E2131 delivers consistent detection performance in high-speed and high-precision automation systems. The laser-based sensing principle enables accurate recognition of small components, transparent gaps, or fast-moving products on conveyors. Rapid signal processing supports applications with short cycle times, helping prevent missed detections and false triggers. Adjustable sensitivity and selectable light or dark switching simplify setup during commissioning and maintenance. With a durable enclosure designed for industrial conditions, this sensor helps reduce unplanned downtime, improves process stability, and supports long-term operational reliability across manufacturing, packaging, and material handling applications.

Automated conveyor systems handling small metal or plastic parts demand extremely fast and reliable detection. The SICK WS/WE100L-E2131 is well suited for this environment because its laser through-beam design creates a narrow, stable detection zone that remains accurate even at high belt speeds. Small items such as fasteners or stamped parts are detected consistently, even when spacing is tight. The fast switching capability supports precise counting and sorting without slowing production. This improves throughput, reduces miscounts, and helps maintain smooth, uninterrupted material flow in automated logistics systems.
Packaging lines often process lightweight products with varying shapes and surface finishes. The WS/WE100L-E2131 provides dependable object detection regardless of color or reflectivity by using a laser beam rather than reflected light. It is commonly used to confirm product presence before sealing, labeling, or grouping operations. Sensitivity adjustment allows the sensor to be optimized for different package sizes, while its compact housing fits easily into confined machine frames. This ensures accurate machine timing, minimizes packaging errors, and helps reduce rejected or damaged products.
In automated assembly processes, confirming that each part is present before the next operation is essential. The SICK WS/WE100L-E2131 supports this requirement by reliably detecting thin or partially hidden components. Its through-beam principle ensures stable sensing even when materials or surface finishes vary. The rapid response time matches short cycle times, preventing process interruptions. By identifying missing or misaligned parts early, manufacturers can reduce scrap, avoid rework, and maintain consistent assembly quality across high-volume production lines.
Material handling applications often rely on accurate detection of product edges or gaps to control stops, diverters, or alignment systems. The WS/WE100L-E2131 delivers precise edge recognition thanks to its focused laser beam and long sensing range. It performs reliably even when products move quickly or are spaced unevenly. The robust industrial design supports continuous operation in demanding environments. This improves flow control accuracy, reduces mechanical jams, and enhances overall system synchronization in automated handling and distribution systems.
