EAO have introduced the new freely configurable, bright and capacitive IO-Link Touch for industrial applications. 

With the advent of digitization in the industrial sector, machine manufacturers can develop completely new machines and equipment. At the same time, this creates an even more intensive operating experience for the end user. However, to reap the benefits of digitization, machine manufacturers must overcome demanding challenges, such as system complexity or the enormous investment of time and money required to digitally transform their analog machines. The Series 84 IO-Link Touch sensitive switch, digital machine systems can now be equipped and operated with HMIs easily and rapidly.

Application-specific HMI variants. With its three HMI variants – standard, stainless steel and hygienic – the IO-Link Touch sensitive switch range offers actuators and indicators which are ideal for a wide range of applications in the mechanical engineering industry and far beyond.

Typical applications

  • Factory automation
  • Industrial controls
  • Material handling
  • Food and beverage processing
  • Packaging equipment
  • Autonomous robotics

Simply digitally networked

Thanks to the globally established IO-Link communication interface and programmable connection options, the innovative HMIs can be networked with an advanced machine system via an integrated M12 5-pin screw connection with a mounting depth of just 25.8 mm, making your equipment Industry 4.0-compatible.

Freely configurable HMIs

The potential use for HMIs is based on a freely selectable configuration which can be precisely aligned to the respective application – from illumination, to symbols, to the switching function. For example, the illumination can switch on with a deliberate delay when actuated. Or HMI operational readiness can be signalled by green illumination which changes to yellow when actuated, and to red a few seconds later. The configuration remains stored on the HMI even with no power supplied.


  • Freely configurable HMIs with IO-Link interface
  • Capacitive Touch Sensitive technology
  • RGB LED illumination in up to 16 million colors
  • IP rating to IP69K with shock resistance IK08
  • Easy industry standard M12 connection
  • Optionally illuminated standard or custom symbols
  • EAO value added services and global availability

Innovative RGB LED illumination. The static or flashing RGB LED illumination in up to 16 million colors is particularly bright. Thanks to the integrated ambient light level sensor, the HMI always illuminates at the right intensity in any lighting conditions – without dazzling or being too dim. This feature also optimizes the HMI’s power consumption as well as LED lifetime. Four lateral illuminated windows integrated into the front frame ensure excellent visibility of the entire status display. Combined with high-contrast and optionally illuminated standard or custom symbols, the attractive design of the IO-Link Touch sensitive switch means it also integrates visually in any modern application setting.
