Housing Material Metal
IO-Link Very likely version 1.1 (This is a key feature of the WSE9L series)
Function IO-Link for smart sensor capabilities

Typical Applications
This sensor is versatile and used wherever reliable detection independent of color and background is needed:

Packaging Machinery: Detecting packages on conveyors, ignoring the belt or machine structure behind them.

Automated Assembly: Verifying the presence of components in a fixture or assembly jig.

Material Handling: Detecting objects on pallets or elevators.

Robotics: Providing presence detection for grippers and end-effectors.

Food and Beverage: Detecting bottles, cans, or packages.
