With the WLL80 opto-electronic fiber optic amplifier, SICK is creating a new generation of amplifiers for the flexible integration of fiber optics in confined spaces. The intelligent WLL80 features IO-Link and can make processes even more efficient with various Smart Tasks. Thanks to IP54, it is protected from dust and spray water during operation. Continuous threshold adaptation ensures good performance in the long term with minimal maintenance requirements. In addition to a fast response time and high detection range, it is characterized by flexible and user-friendly parameterization via the OLED display or IO-Link. Whether as a single or bus version, the WLL80 is suitable for a wide range of applications thanks to its extensive fiber optics portfolio.

User-friendly parameterization right on the device
The WLL80 can be set easily and directly on the sensor thanks to its sharp OLED display. The menu offers intuitive operation using the pushbutton located on the side of the display. This means the fiber optic amplifier can be re-parameterized on site and easily adapted to the respective conditions. The menu is available in English, German, Chinese, Japanese and Korean, which makes it possible to correctly control the device in the different language areas.
The OLED display ensures user-friendly operation of the WLL80 and enables quick and easy adjustment to changing conditions on site.
State-of-the-art communication interfaces for single or bus use
The WLL80 has a modern IO-Link interface for communication. This reduces the required cabling and allows for efficient bidirectional exchange between sensor and plant system. This allows for automatic parameterization and continuous monitoring of the WLL80 in real time. The fiber optic amplifier can be used as a single sensor or bus configurations. The bus interface makes it possible for several sensors to be networked via an Ethernet-based bus protocol using the WI180C communication gateway. The integrated anti-interference logic prevents mutual interference between the sensors.
Thanks to the state-of-the-art IO-Link technology, quick parameterization, sensor data in real time and simple troubleshooting significantly reduce the time and effort needed for installation and maintenance of the WLL80.
Wide range of functions for maximum flexibility in use
The WLL80 can be used as a through-beam photoelectric sensor or photoelectric proximity sensor. For maximum operational safety, mechanical elements indicate whether the fibers in the amplifier are correctly fastened. The intelligent sensor features a number of Smart Tasks that ensure high efficiency and the best possible quality of detection results. Predefined parameter configurations for specific applications – so-called jobs – ensure reliable detection of fast, small or transparent objects as well as precise edge detection. The sensor data can also be used for predictive maintenance and IoT functions.
Intelligent and powerful – the WLL80 ensures consistently high-quality detection results with Smart Tasks and useful diagnostic functions.
