Extending its WDGA series of absolute encoders, Wachendorff Automation, the Geisenheim/Germany-based encoder manufacturer is using PROFINET-IO and EtherCAT Industrial Ethernet interfaces. With the new WDGA58F, Wachendorff has succeeded in constructing the world's smallest design in both diameter and length. As the trend towards ever more compact systems continues undiminished, this saves valuable installation space which can be crucial in new or retrofitted machines.
