SICK WF50-60B410 Infrared Fork Sensor for High-Speed Detection

SICK WF50-60B410 Fork Sensor – High-Speed Infrared Optical Detection

The SICK WF50-60B410 fork sensor with infrared optical detection is a compact and precise sensing solution designed for fast and accurate detection of small objects and thin materials. Built with a 50 mm fork opening, it reliably identifies items as small as 0.2 mm while maintaining stable performance at high switching speeds. The integrated infrared light source and optical detection principle ensure consistent results even in demanding automation environments. With a rugged metal housing and industrial-grade protection, this sensor is well suited for continuous operation in production lines where reliability and repeatability are essential.

The SICK WF50-60B410 helps manufacturers achieve dependable detection in applications involving rapid motion and tight tolerances. Its very fast response time supports high-speed processes without signal loss, making it ideal for detecting labels, edges, or small components. Sensitivity and switching behavior can be adjusted directly on the device, reducing setup time during installation or product changeovers. The ability to work with both PNP and NPN outputs simplifies system integration, while strong resistance to ambient light improves detection stability. Together, these features help reduce errors, improve process efficiency, and maintain consistent product quality across automated operations.

Why SICK WF50-60B410?
The SICK WF50-60B410 stands out because it combines precision, speed, and simplicity in one compact fork sensor. It detects extremely small objects while keeping pace with high-speed production lines, all without complex setup. On-device adjustment, flexible output options, and a robust industrial design make it a practical choice for engineers who want dependable performance, fast commissioning, and long-term stability in real manufacturing environments.

What problem does it solve?
The SICK WF50-60B410 solves the challenge of reliably detecting thin, fast-moving, or low-contrast objects that traditional sensors often miss. It eliminates inconsistent readings caused by vibration, ambient light, or rapid motion. By delivering accurate, repeatable detection at high speeds, it helps prevent missed labels, counting errors, and quality defects that can disrupt automated processes and reduce overall production efficiency.

The Applications

1. Precision Label Gap Detection on High-Speed Packaging Lines

On modern packaging lines, accurate label positioning depends on detecting extremely small gaps between labels moving at high speed. The SICK WF50-60B410 can be installed directly at the dispensing point, where the label liner passes through the fork opening. Its fast response time allows it to detect each label edge precisely, even during rapid acceleration or deceleration. By maintaining stable detection regardless of vibration or changing web tension, the sensor helps ensure consistent label placement. This reduces misapplied labels, lowers material waste, and minimizes costly downtime caused by rework or manual adjustments.

2. Reliable Double-Sheet Detection in Paper and Carton Feeding Systems

In printing and carton forming equipment, feeding more than one sheet at a time can lead to jams, misprints, or damaged products. The SICK WF50-60B410 addresses this issue by monitoring material thickness changes as sheets pass through the fork. Its high sensitivity allows operators to distinguish between a single sheet and overlapping material with confidence. Because the emitter and receiver are fixed within the fork, alignment remains stable over time. This results in fewer false alarms, smoother feeding, and improved process reliability in high-volume paper handling applications.

3. Perforation and Hole Sensing on Flexible Packaging Films

Flexible packaging machines often rely on perforations or punched holes to synchronize cutting, sealing, or indexing operations. The SICK WF50-60B410 can detect these features as the film moves through the sensor at speed. Its consistent switching performance ensures precise timing signals for motion control systems, even under bright ambient lighting conditions. This accuracy helps maintain correct registration between printed graphics and mechanical actions. As a result, manufacturers benefit from cleaner cuts, better seal alignment, and reduced scrap during continuous production and frequent product changeovers.

4. High-Speed Part Detection and Counting in Automated Assembly

Small components moving quickly through automated assembly lines can be difficult to detect reliably. The SICK WF50-60B410 is well suited for counting or presence verification of clips, stamped parts, or molded components passing through its fork. Its fast switching capability ensures that no parts are missed, even at high throughput rates. Flexible output options simplify integration with different control systems, while the robust housing supports long-term industrial use. This improves count accuracy, supports traceability requirements, and helps maintain stable production flow without unexpected interruptions.
