io-key - Unlock a new Dimension of Business

Currently, centralised monitoring of sensor data of small or decentralised applications is rather difficult and comparatively expensive. High initial investments for the required infrastructure and expensive wiring are often the reasons why such projects are not very attractive and unprofitable. However, there is finally a solution: io-key!

What makes it special: io-key transfers the data of the connected sensors via mobile network (NB-IoT or 2G network) to a secured cloud where the user can access the clearly structured data in a dashboard - no matter when, no matter where. Long and expensive wiring to reach distant sensors is prone to errors and has become a thing of the past, just like over-dimensioned, expensive infrastructures while using only a small number of sensors.

Monitoring decentralised processes and installations can be that simple.

io-key in detail

io-key in detail: simple, convenient, powerful

Simple: installation saves time and money
With io-key, you will opt right from the beginning for an easy-to-handle, yet powerful form of process and plant monitoring. A power supply and an available GSM network – this is all that io-key requires to transmit the data of the connected IO-Link sensors to the cloud. There is no need for complex connection to the company network or to a controller.

Convenient: alarm function by email or text message, automatic reports
The clear dashboard allows the user to set limit values for the connected sensors with just a few mouse clicks. If these limit values are exceeded, the user will be alerted by email or text message. Moreover, all kinds of data can be summarised and exported automatically in the form or reports.

Powerful: sturdy housing, vast choice of sensors
Whether in a dusty environment or outdoors, thanks to protection rating IP65, io-key is the perfect solution for all kinds of applications. Thanks to two sensor connections, a great variety of monitoring scenarios can be implemented. ifm has many different IO-Link sensors in store for this purpose.

At a glance

At a glance: the advantages of io-key


  • Plug & play monitoring: sensor-supported plant monitoring without network planning or cabling
  • Easy set-up: connect io-key to a power supply, connect the sensor(s) to io-key, register at the ifm cloud. That's it! Now you can read out the sensor data.
  • High flexibility: the installation location can be freely selected – thanks to IP65 even outdoors. Free choice of a great number of IO-Link sensors for all kinds of applications
  • Efficient: low cost in comparison to other industrial cloud solutions


io-key in practice: application examples

Monitoring of old machines via radio gateway
Up until now, it was common to connect the IO-Link sensor directly to the PLC. However, since the PLC only processes the switching signals, about 95 percent of the process information will be lost. By using io-key, this digital information can now be transferred directly from the process to the cloud and then be used for more accurate machine analysis.

Pressure monitoring at pumping stations
With io-key, you can keep an eye on the proper pumping function of remote or mobile pumping stations at any time. An alarm function immediately reports deviations from the preset value so that the required pumping capacity can be quickly restored.

Level measurement on tanks
Feed silos, tanks for printing ink or concrete additives have one thing in common: they should be refilled before they are completely empty. Suppliers who equip their customer's tanks with io-key can guarantee reliable, uninterrupted product supply. Once a defined level has been reached, logistics can automatically initiate refilling. A great improvement in service quality!

Predictive maintenance on remote machines
Fans in decentralised cold stores or storage facilities can be monitored via io-key as well as remote motors or pumps, for example, in automated agriculture. Damaged bearings, unbalance and similar signs of imminent machine damage will be detected by vibration sensors and reported to the central dashboard via io-key. This prevents unplanned interruption of work processes while the product quality will be maintained thanks to constant storage conditions.
