With the advent of digitisation 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 digitisation, machine manufacturers must overcome demanding challenges, for instance in terms of system complexity or the enormous investment of time and money required to digitally transform their analogue machines. With the Series 84 IO-Link Touch, digital machine systems can be equipped and operated with HMIs easily and rapidly.

With its three HMI variants – standard, stainless steel and hygiene – the IO-Link Touch range offers actuators and indicators which are ideal for a wide range of applications.

The many potential uses for the HMIs are 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.

Typical applications

  • Automated production (smart factories)
  • Controls and switch cabinets
  • Food and beverage industry
  • Packaging equipment
  • Autonomous robot transport systems
  • Monitoring stations for industrial conveyor belts
  • Mobile, medical devices
  • Transmission systems for telecommunications
  • Video router systems


  • Freely configurable HMIs with IO-Link interface (Industry 4.0)
  • Optionally illuminated standard or custom symbols
  • Ambient light adaptive RGB LED illumination in 16 million colours
  • Capacitive actuation with different actuation sensitivities
