Key Features
-
Background Suppression (BGS): The Twin Eye technology ensures precise distance measurement, allowing the sensor to detect objects within the set range while ignoring the background, regardless of color or surface texture.
-
IO-Link Smart Sensor: Provides parameter setting, diagnostics, and process data (e.g., measured distance) via IO-Link, enabling predictive maintenance and easy integration into Industry 4.0 environments.
-
Robust Design: The VISTAL® housing offers high resistance to chemicals, impacts, and UV radiation, making it ideal for demanding applications in automotive, packaging, and material handling.
-
Flexible Output: The push-pull output supports both PNP and NPN switching modes, allowing compatibility with a wide range of PLCs and controllers without hardware changes.
Applications
-
Material Handling: Object detection on conveyors, pallet positioning, and bin level monitoring.
-
Packaging Machinery: Detection of transparent films, bottles, and packaging materials.
-
Automotive Assembly: Presence sensing of components on assembly lines and robotic cells.
-
Logistics: Parcel sorting and dimensioning in distribution centers.
