Product Description

The SICK WFS3-40P115 (6055433) is a high-performance optical fork sensor specifically engineered for the rigorous demands of the labeling and packaging industries. Its slim, U-shaped design allows for direct mounting on the edge of label dispensers, making it an ideal solution for detecting non-transparent labels on various web materials. Utilizing infrared light, the sensor excels in identifying label gaps with extreme precision, even when dealing with high-speed production lines.

The device features a highly intuitive adjustment system, utilizing plus/minus buttons for 2-point teach-in or dynamic teach-in via cable. This allows operators to set switching thresholds while the label strip is in motion, significantly reducing setup time and increasing process reliability. With a rapid response time of 50 µs and a switching frequency of 10 kHz, the WFS3-40P115 ensures exceptional repeat accuracy. Housed in a durable IP65-rated glass-fiber reinforced plastic casing, this sensor provides long-term stability and resistance to industrial environments, ensuring seamless integration into automated factory workflows.

Key Performance Features

• High Switching Frequency: Operates at up to 10 kHz for precise detection in high-speed applications.
• Rapid Response Time: Extremely low latency of ≤ 50 µs with a jitter of only 40 µs.
• Advanced Teach-In: Supports both manual 2-point teach-in via buttons and dynamic teach-in during operation.
• Fine Object Detection: Capable of detecting a Minimum Detectable Object (MDO) gap of 2 mm.
• Robust Environment Rating: Enclosure rating of IP65, suitable for standard industrial operating temperatures from –20 °C to +60 °C.
• Flexible Configuration: User-defined light/dark switching function and adjustable sensitivity.

Ideal Applications

• Labeling Machines: Accurate detection of label gaps and edges on high-speed dispensing systems.
• Packaging Industry: Detection of non-transparent labels on a wide variety of carrier materials.
• Double Sheet Detection: Monitoring feed systems to prevent multiple sheets or layers from passing simultaneously.
• Web Guiding: Positioning and tracking of web-based materials in printing or processing equipment.
• Small Part Detection: Reliable sensing of small opaque objects in narrow transport tracks.
