Product Description

The SICK 6058649 (WFS3-40B41CA00) is a high-performance fork sensor specifically engineered for the precise detection of labels on carrier materials. Utilizing an infrared light source, this sensor excels in high-speed applications thanks to its exceptional switching frequency of 15 kHz and a rapid response time of 46 µs. Its slim, glass-fiber reinforced plastic housing (10 mm width) allows for seamless integration into tight machine spaces commonly found in packaging and labeling lines.

The device is equipped with advanced “Smart Sensor” capabilities, featuring an integrated IO-Link interface that facilitates easy configuration, monitoring, and diagnostics. Users can perform adjustments via a physical Teach-in button on the housing or remotely through a control cable. Supporting 1-point, 2-point, and dynamic Teach-in modes, the WFS3-40B41CA00 ensures reliable performance even when dealing with varied label materials or transparent foils. With an IP65 rating and a wide operating temperature range from –20 °C to +60 °C, it provides industrial-grade durability for demanding automated environments.

Key Performance Features

High-Speed Processing: 15 kHz switching frequency and 46 µs response time for maximum throughput.
Flexible Adjustment: Supports manual Teach-in (1-point, 2-point, dynamic) via button or external cable.
Smart Communication: IO-Link integration allows for parameter cloning, health monitoring, and easy sensor replacement.
Robust Output: Push-pull switching output (PNP/NPN) compatible with most PLC inputs.
Compact Design: Ultra-slim 10mm housing width saves critical installation space.
Reliable Detection: Optimized for detecting a wide variety of labels, including those with small gaps down to 2 mm.

Ideal Applications

Labeling Machines: High-speed detection of adhesive labels on carrier film.
Packaging Industry: Monitoring label presence and alignment on conveyor belts.
Printing Processes: Detecting register marks or gaps in continuous web materials.
Assembly Lines: Sensing small parts or edges within the 3mm fork gap.
Food and Beverage: Automated labeling of bottles, cans, and cartons in clean, dry environments.
