IO-Link technology – Your gateway to the Smart Factory
Baumer sensors offer the best and most reliable sensor functions. With the IO-Link technology, the functions integrated directly in the sensor can be easily parameterized. Sensors are immediately ready to use and optimally adjusted to the respective application. IO-Link also makes it possible to transmit a wide range of additional information directly from the sensor to the OT world or IT world, making for more effective systems – your gateway to the digital factory.
What is IO-Link?
- A manufacturer-independent digital communication protocol/interface
- IO-Link enables the bidirectional exchange of process data (measured values and status information), parameters for configuring the sensor, together with event and diagnostic data for feedback on faults or additional information
- An IO-Link connection is always established between an IO-Link master and an IO-Link device (actuator & sensor)
- Unshielded standard M8/12 cabling can still be used for IO-Link
- The IO-Link master is the gateway for open connections to all fieldbuses and various IT protocols (IT/OT communication)
- IO-Link is an open industry standard
Advantages of IO-Link
- Easy commissioning & fast sensor exchange
- Diagnostic data for condition monitoring for optimized processes
- Loss-free transmission of measured values thanks to digital communication
- More sensor information for reliable control of systems & machines
- Precise parameterization of sensor functions
- Efficient engineering thanks to PC-based sensor tools

Backward compatibility
As explained in the section What is IO-Link?, IO-Link masters can also read in and output switching signals. All IO-Link devices can also be used as switching devices by default. This ensures backwards compatibility at all times.
IO-Link dual channel
The term “IO-Link dual channel” was coined by Baumer and refers to sensors that have additional switching or analog outputs alongside the IO-Link communication.
Thanks to IO-Link dual channel, it is possible to operate very fast processes or existing analog interfaces and at the same time enjoy the benefits of IO-Link technology (e.g. parameterization, condition monitoring, etc.).
