E-stop signals and other safe signals via standard WLAN

The Bihl+Wiedemann safe coupling Safe Link enables safe communication via standard WLAN*: For example, if a stationary E-stop is actuated, it is also possible to safely switch off moving wireless applications. Use the wireless form of safe communication for automated guided vehicle systems (AGV systems), storage and retrieval machines (SRMs), conveyor systems in underground mining or other mobile applications.


* WLAN components have to be ordered directly from the respective manufacturer. Devices with Safe Link are compatible with almost all available suppliers.
