Optimize your labeling process with the SICK WFS3-40B41CA70 fork sensor. Features 3mm fork width, IO-Link, and 15kHz switching frequency for high-speed label detection.
The SICK WFS3-40B41CA70 is a high-performance optical fork sensor specifically engineered for the rigorous demands of the labeling industry. Utilizing a slim, forked housing design, this sensor is optimized for direct mounting on the edge of label dispensers, facilitating precise detection of label gaps even in space-critical installations. The device employs infrared light to ensure reliable detection of a wide variety of labels on carrier materials, regardless of color or surface texture.
A standout feature of the WFS3 series is its “Smart Sensor” capability, integrated via an IO-Link interface. This allows for advanced diagnostics, remote configuration, and easy integration into Industry 4.0 environments. The sensor supports multiple teach-in methods—including a manual teach-in button, plus/minus buttons, or via IO-Link—allowing for the switching threshold to be adjusted while the label strip is in motion. With a rapid response time of 50 µs and a switching frequency of up to 15 kHz, the WFS3-40B41CA70 ensures exceptional repeat accuracy and process stability in high-speed automated packaging lines.
