IO-Link is a digital point-to-point connection based on a 3-wire connection. IO-Link is an efficient communication technology.

IO-Link improves communication between sensors/actuators and controllers through a reliable, digital point-to-point connection.
It reduces wiring effort, increases data availability, and supports intelligent automation.
IO-Link is a manufacturer-independent, standardized point-to-point communication system for connecting sensors and actuators to an automation system.
Components of an IO-Link System
- IO-Link Devices: Devices such as sensors or actuators that are connected via IO-Link
- IO-Link Master: The interface to the controller or to the higher-level fieldbus, which communicates directly with the IO-Link devices
In times of intelligent manufacturing, increasing connectivity and automation have led to radical improvements in production speeds and product quality. Nevertheless, efficiency is very often hampered by a lack of standardization in the automation components that are essential for a machine or system. This gap is closed by our product offering, by providing sensors with an IO-Link interface.
Advantages of IO-Link
The advantages of IO-Link interfaces are obvious and will be briefly explained below.
- Integrated electronics save space in the control cabinet
- Standard cables and standard M12 connectors enable quick and easy installation
- Standardized IO-Link sensor interfaces can be used freely, regardless of the network (e.g., Ethernet- or fieldbus-based)
- Plug-and-play integration
- Simple and reliable sensor replacement
- Automatic cloning by IO-Link master prevents incorrect settings
- Minimized downtime
- Statistics - maximum, minimum, peak value, operating counter or load collective
- Easy parameterization and diagnosis
IO-Link Load Cells from octogon
All our force transducers and load cells can be equipped with an IO-Link measuring amplifier or an IO-Link interface. Depending on the design - especially depending on the size of the sensor - we essentially offer two versions:
- Load cells or force transducers with an IO-Link output integrated into the sensor housing - for larger designs where sufficient installation space is available.
- Load cells or force transducers with an IO-Link interface integrated into the cable - for compact sensors where direct installation into the housing is not possible, the interface is housed in the connection cable to save space
The modular design and the flexible design of the IO-Link variant integrated into the housing enable direct integration of the interface for most sensors – without adjustments to the sensor design.
