High-precision SICK WS/WE100L-E2231 laser through-beam sensor for long-range, high-speed detection of small objects in industrial automation.
The SICK WS/WE100L-E2231 W100 Laser through-beam photoelectric sensor is engineered for precise long-range object detection in demanding industrial automation tasks. By using a visible red Class 1 laser, it delivers stable sensing performance over distances up to 30 m, even when detecting very small or fast-moving targets. Its slim W100 housing supports installation in tight mechanical spaces, while laser-based alignment simplifies setup and improves detection accuracy in applications where conventional photoelectric sensors are not sufficient.
In practical use, the SICK WS/WE100L-E2231 W100 Laser sensor enables reliable detection on high-speed conveyors, packaging lines, and automated handling systems. The concentrated laser beam allows consistent sensing of thin edges, small components, or rapidly passing objects without signal instability. A very short response time supports fast production cycles, while selectable light/dark switching adapts easily to different control logic. With a durable IP65 enclosure and wide operating voltage range, the sensor minimizes downtime and ensures dependable performance in continuous industrial operation.
The SICK WS/WE100L-E2231 is chosen when precision, speed, and reliability must coexist in one compact sensor. Its laser-based through-beam design delivers exceptional accuracy over long distances while remaining stable on high-speed lines. The slim W100 housing fits easily into tight machine layouts, and the fast switching response supports modern automation where milliseconds matter. It is built for engineers who need confident detection without constant recalibration or complex setup.
The SICK WS/WE100L-E2231 solves the challenge of detecting small, thin, or rapidly moving objects that traditional photoelectric sensors often miss. In long conveyor runs or fast packaging systems, standard light sources can lose contrast or accuracy. This laser sensor maintains a concentrated beam and rapid response, ensuring consistent detection, fewer false signals, and reliable process control even under demanding industrial conditions.

In automated packaging lines, cartons often arrive at high speed with uneven spacing or slight misalignment, making accurate detection difficult. A laser through-beam sensor such as the SICK WS/WE100L-E2231 can be installed across the conveyor to precisely detect the leading edge of each carton. Its fast response time allows the control system to react instantly, ensuring accurate stopping, labeling, or diverting. Because detection is based on beam interruption rather than surface reflection, changes in carton color, print, or surface finish do not affect performance. This results in consistent positioning, reduced rejects, and smoother operation in high-throughput packaging and material handling systems.
Counting small items such as bottles, caps, or electronic components becomes challenging when products are closely spaced and moving quickly. Using a laser through-beam configuration, the SICK WS/WE100L-E2231 provides clean and repeatable signals each time an object passes through the beam. The narrow laser spot and high switching frequency ensure that even short gaps between products are detected accurately. This improves counting reliability for batching, filling, or downstream quality checks. The result is improved production accuracy, fewer counting errors, and better synchronization with robotic pick-and-place units or automated packaging stations.
Detecting products inside transparent or glossy packaging is a common challenge in food, pharmaceutical, and consumer goods production. Reflective sensors often struggle due to glare or inconsistent reflections from plastic films. A through-beam laser sensor like the SICK WS/WE100L-E2231 overcomes this by detecting the physical interruption of the beam, regardless of packaging material. This makes it ideal for confirming product presence before sealing or labeling. Its long sensing distance allows flexible mounting across wide machines, reducing mechanical constraints while maintaining stable detection even when packaging materials or product types change frequently.
In automated assembly, reliable detection of small parts moving through chutes or feeder tracks is essential to avoid jams or missing components. The SICK WS/WE100L-E2231 can be mounted across narrow passages to confirm that each part has passed the inspection point. Its rapid response supports fast-moving parts without missed signals, while the non-contact laser method eliminates mechanical wear. This enables precise feeder control, immediate fault detection, and stable cycle times. In practice, it helps protect downstream tooling, reduces scrap, and improves overall equipment effectiveness in assembly, inspection, and kitting applications.
