Wachendorff has developed its solid-shaft encoder WDG 58V specially for the food and pharmaceutical industries, where the demands for hygiene and cleanliness are of the utmost importance. Both housing and shaft are manufactured from V4A stainless steel, and PTFE was selected for the dead-space-free radial shaft seal. Both the design and construction of these professional encoders satisfy strict regulatory requirements. So, for example, WDG 58 V meets the high protection rating IP69K and is certified by the independent institutions Ecolab and EHEDG.
