The SICK WLL180 Series Fiber-Optic Sensor offers a high operating reserve and resolution, with fast response times down to 16μs. Adjustment methods are straightforward as well as versatile, via a teach-in button on the unit or external teach-in via cable input. Hysteresis and time delays are configurable to suit system needs, such as the detection of extremely small or transparent targets. The two, 4-digit displays present a user-friendly interface to showcase programming steps, status updates and target vs. actual values. Units feature anti-interference logic. The WLL180 Series comes in stand-alone variants, or with an internal bus for networking with other sensors. In this configuration, settings for the WLL180 Series can be mapped over to any other bus-connected devices.
