  • Offers extended range sensing for metal versions allows mounting further away from target which reduces chance of impact and related damage
  • Provides a range of switching frequencies up to 5000 Hz
  • Includes cable, quick-disconnect and pigtail cable with M8 or M12 connection styles
  • Offers IP67 and IP69K rated models
  • Typical applications include:
    • Automation
    • Food processing
    • Material handling
    • Packaging
    • Washdown applications
    • Welding and stamping applications

Sensors on IO-Link Can Enable the Connected Enterprise

Watch how smart sensors with IO-Link can enable smart machines for The Connected Enterprise.

IO-Link Technology

IO-Link Technology is a worldwide open-standard protocol that integrates sensors into our Connected Enterprise by connecting the IO-Link enabled device into an IO-Link master module. You can deliver data from the sensor directly into a control system in a very efficient manner. The flexibility of IO-Link capable sensors allows machines to operate more effectively by providing the controller with diagnostics. In addition to product detection, sensors provide detailed and accurate machine health status to improve uptime.
