Product Description

The SICK WFM80-60N321 is a high-performance, fork-style photoelectric sensor designed for effortless integration and “plug-and-play” operation. With a generous fork width of 80mm and a depth of 60mm, this sensor utilizes a visible red LED light source to provide highly accurate object detection without the need for complex alignment or sensitivity adjustments. Its fixed setting ensures consistent performance and simplifies the installation process, making it an ideal choice for fast-paced industrial environments.

Engineered with a robust aluminum housing and an IP67 rating, the WFM80 is built to withstand harsh conditions while maintaining a rapid response time of 125 µs and a high switching frequency of 4 kHz. This makes it exceptionally reliable for detecting labels, edges, or small parts on high-speed conveyor systems. The NPN output and dark-switching logic provide seamless compatibility with various control systems. By eliminating the need for manual calibration, SICK’s WFM series reduces downtime and commissioning costs while delivering the precision required for modern automated logistics and manufacturing processes.

Key Performance Features

Plug-and-Play Setup: Fixed sensitivity and “no-adjustment” design allow for immediate commissioning.
High-Speed Accuracy: Rapid 4,000 Hz switching frequency ensures precision at high production speeds.
Visible Red Light: The bright red LED light source enables easy alignment and visual monitoring.
Rugged Durability: IP67-rated aluminum housing provides excellent resistance to dust, water, and vibration.
Integrated Design: Sender and receiver are pre-aligned in a single metal housing, preventing misalignment issues.

Ideal Applications

Packaging Industry: Detecting labels on bottles or containers and monitoring film edges.
Logistics & Conveying: Small part detection and position sensing on high-speed conveyors.
Printing & Paper: Monitoring paper paths or counting sheets in feed systems.
Electronics Assembly: Detecting the presence of components or tracking PCB edges during transport.
Machine Building: General-purpose object counting and gap detection in automated machinery.
