SICK WLL180 fibre-optic amplifier

When the installation space at the detection site of a machine is not large enough even for a miniature sensor, fibre-optic sensors are often the only option for detecting objects. The separation of optics and evaluation make it possible to come close to the detection object both with scanners and with through-beam systems. High temperatures, aggressive oils, chemicals or mist are conditions in which the appropriate versions of fibre-optic sensors are needed. In both hidden and invisible mounting, fibre-optic sensors often have the decisive advantage that their amplifiers can be installed at easily accessible places.

The WLL180 fibre-optic amplifier has a compact size, a fast response time of 16 µs and high light intensity and resolution, which ensures an additional operating reserve in dusty operating environments.

Sensing distances of up to 20 m are possible and its high light intensity delivers a high-powered solution — even in difficult ambient conditions, like dust, spray, mist and water jets. Commissioning is simple — either via the external teach-in input or directly on the unit. Two four-digit displays provide visualisation of all programming steps and status displays, plus target and actual values through an intuitive menu structure.

The WLL180T sensors can be operated either stand-alone or in a bus configuration, depending on the requirements. In a bus configuration, several sensors are networked via an internal bus, enabling the settings on one WLL180T to be copied to all other devices on the bus.
