Hilschers netFIELD Device IO-Link Wireless Master extends the scope of IO-Link compatible sensors and actors to the wireless spectrum. This opens up new possibilities for plant operators and machine builders to equip their devices with industrial sensors and actuators and integrate them easily and reliably into industrial networks.

Based on the proven hardwired IO-Link standard, users of IO-Link Wireless can rely on familiar technologies and equip inaccessible sensors or actuators in production plants, robots with high degrees of freedom or legacy systems with IO-Link technology. Potential failure points such as broken cables are eliminated and downtimes can be reduced.

Reduction of Installation Efforts

Wireless point-to-point technology enables the cyclic exchange of input and output process data between the Master and its associated devices.

Reduction of Installation Efforts

  • Sensors are auto detected and configured
  • No additional PLC needed
  • Complex sensors can be parameterized onsite

Higher Range of Motion

Utilizing wireless technology for data transmission minimizes movement restrictions for industrial robots, cobots and other machines.

Higher Range of Motion

  • No limiting cable connection needed
  • Can complement existing installations and machinery
  • Proven IO-Link technology guarantees interoperability

Accessibility of Space Limited Areas

Sensors and actuators only require a power supply to transfer data via Hilschers netFIELD Device Wireless Bridge to the master and vice versa.

Accessibility of Space Limited Areas

  • You are good to go with just a 24 V power supply
  • No sensitive cables and connectors in confined spaces

Alleviate Downtimes

Wireless data connections will not break due to physical stress as a result of moving robot arms for example.
