Contrinex IO-Link Double Blank Sensor

Smarter Double Sheet Detection with IO-Link

In this demo, Cody from the HH Barnum Applications Team showcases the new Contrinex IO-Link Programmable Double Blank Sensor — a powerful upgrade to Contrinex’s proven double sheet detection technology.

Unlike previous versions that required PocketCoder software for setup, this new sensor is fully programmable over IO-Link, allowing configuration directly through your PLC and HMI.

Simplified Setup. Greater Flexibility.

The upgraded sensor features enhanced processing power and onboard storage capable of holding up to 15 material configurations. Contrinex also offers more than 25 preconfigured material profiles for common materials including:

  • Stainless steel
  • Aluminum
  • Galvanized steel
  • Various steel thicknesses

Additional material configurations can be added as new applications are developed.

Key Features

  • Fully programmable via IO-Link
  • PLC and HMI integration
  • No PocketCoder or extra hardware required
  • Available in 18 mm and 30 mm versions
  • ActiveStone™ coated sensing face
  • Fast device replacement and hot-swapping capability

Designed for Modern Automation

Using IO-Link process data, operators can:

  • Change material configurations remotely
  • Monitor live sensor values
  • Perform teach commands directly from the HMI
  • Receive real-time sensor feedback and status updates

The result is faster setup, easier integration, and reduced downtime on the plant floor.
