To count, measure, detect – the tasks of Baumer sensors in machinery and installations are very clear. But there is much more to the small power packs. Many Baumer sensors feature IO-Link, a fast communication interface that besides measured values transmits a great bunch of additional information – in both communication directions. Sensors with IO-Link connectivity communicate with a master addressing up to eight sensors. The stored master parameter data can thus be distributed to several individual sensors. This allows for much more precise sensor adjustment in the application, which is a special benefit where processing different objects on a machine. Another advantage: The deployed sensor can switch functionality, for example an inductive sensor can be used as frequency meter or counter. IO-Link is therefore indispensable in digitization and a must-have for Industry 4.0 and IIoT.
