Fiber-optic sensors
WLL180T

High-performance fiber-optic sensor with world’s fastest response time

Your Benefits

  • Reliable, rapid process detection, even under the most difficult ambient conditions, such as dust, spray or mist
  • Easy commissioning and product changeover due to external teach-in
  • Cross-talk is eliminated when utilizing bus configuration option
  • Quick, easy setup and adjustment due to an intuitive operating menu
  • Flexible parameter adjustment due to high-resolution signal processing. Hysteresis and time delays can be adapted to suit the application, e.g., when detecting tiny or transparent objects
  • Easy-to-read display, even under difficult installation conditions

Overview

High-performance fiber-optic sensor with world’s fastest response time

The WLL180T fiber-optic photoelectric sensor family provides the world’s fastest response time - only 16 μs. In addition, it offers superior sensing distances of up to 20 m and its high light intensity delivers a reliable, 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 visualization of all programming steps, status displays, plus target and actual values through an intuitive menu structure. The WLL180T sensors can be operated either as a 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. Fiber-optic amplifier cross-talk is prevented by the sensors’ integrated anti-interference logic.
