IO-Link - M17 modules are industrial automation components produced by various manufacturers, primarily from Germany and the United States. These modules are part of the IO-Link system, a standardized communication protocol (IEC 61131-9) for sensors and actuators. Companies like Balluff, IFM, and Pepperl+Fuchs offer M17-sized IO-Link modules, which are compact and designed for harsh industrial environments. They serve industries such as manufacturing, automotive, and logistics, enabling smart sensor connectivity, real-time data exchange, and device parameterization. Key products include IO-Link masters, hubs, and interface modules supporting M17 connectors, which facilitate easy integration into industrial networks like PLCs and IIoT systems.
