SICK WS/WE45-N250 through-beam photoelectric sensor for long-range, reliable object detection in harsh industrial environments with high stability.
The SICK WS/WE45-N250 through-beam photoelectric sensor is designed for dependable object detection across very long distances in industrial environments. It addresses detection challenges where conventional sensors lose stability, especially in large open spaces or outdoor installations. Using focused infrared LED technology, the sensor pair delivers precise and consistent detection over several hundred meters. Its rugged metal housing and high ingress protection rating ensure reliable operation under harsh mechanical and environmental conditions, making it well suited for logistics yards, bulk material systems, and large-scale automation setups.
The SICK WS/WE45-N250 offers stable performance by combining a narrow optical beam with high signal strength, reducing interference from ambient light and airborne particles. Built-in front window heating minimizes downtime caused by condensation or icing, while adjustable sensitivity and delay settings allow fine-tuning for challenging applications. Fast switching response supports dynamic processes, and the wide operating voltage range simplifies integration into existing control panels. Overall, the sensor enhances detection reliability, lowers maintenance demands, and improves operational continuity in demanding industrial use cases.
The SICK WS/WE45-N250 is chosen when standard photoelectric sensors reach their limits. It is built for applications that demand reliable detection across very long distances without sacrificing accuracy. Its focused infrared beam, stable signal processing, and robust metal construction make it suitable for harsh industrial environments. Features such as adjustable sensitivity, time-delay control, and front screen heating allow the sensor to remain dependable in rain, dust, fog, or temperature fluctuations, ensuring consistent system performance with minimal maintenance intervention.
The SICK WS/WE45-N250 solves the challenge of detecting objects accurately over extended ranges where reflective or short-range sensors fail. In large facilities, outdoor conveyor lines, or perimeter monitoring systems, ambient light, weather conditions, and airborne particles often cause false signals or missed detections. This through-beam sensor overcomes those issues by maintaining a strong, precisely aligned optical path, delivering stable switching behavior, reducing false triggers, and ensuring continuous operation even in demanding industrial conditions.

In bulk handling operations such as cement plants, grain terminals, or mining sites, conveyor systems often run across long, open distances where dust and vibration are unavoidable. The SICK WS/WE45-N250 is installed across extended conveyor sections to verify material flow and detect belt stoppages. Its through-beam design maintains stable detection even when airborne particles are present. Adjustable sensitivity allows precise tuning to suit different belt widths and materials, while delay functions prevent false signals from falling debris. The rugged metal housing and sealed construction support continuous operation in harsh industrial conditions.
Logistics hubs and freight terminals require dependable vehicle detection across wide access points and long approach distances. The SICK WS/WE45-N250 is used to identify trucks entering or leaving loading zones without relying on reflective surfaces. Its narrow infrared beam delivers accurate detection under strong sunlight, rain, or nighttime operation. Integrated front window heating helps prevent fogging caused by humidity or temperature changes. Fast response times ensure smooth control of automated gates, warning signals, and traffic management systems in large outdoor logistics environments.
Manufacturing plants, warehouses, and utility facilities often implement optical barriers to monitor restricted zones. The SICK WS/WE45-N250 is deployed along perimeters to form a long-distance detection line that identifies unauthorized access attempts. The extended sensing range minimizes the number of sensor pairs required, reducing installation complexity. Adjustable delay settings help ignore momentary interruptions caused by wildlife or weather effects. With its durable metal enclosure and wide voltage tolerance, the sensor supports continuous outdoor use with minimal maintenance requirements.
In heavy industries such as steel processing or large-scale fabrication, overhead cranes and gantry systems require precise movement monitoring to prevent collisions. The SICK WS/WE45-N250 is installed across crane travel paths to confirm position limits or detect crane presence in defined zones. Its fast switching capability supports dynamic motion detection, while precise beam alignment ensures reliable performance over long spans. Resistance to dust, heat, and vibration makes the sensor suitable for demanding production environments where downtime must be minimized.
