ATEX-compliant shaft encoders

Safe explosion protection through ATEX-compliant housing

A particular challenge for shaft encoders are explosive atmospheres such as transfer systems in painting lines, filling/bagging stations in grain mills, petrol pumps at filling stations, or geothermal energy environments.

As an accredited manufacturer of explosion-proof enclosures, we offer ATEX-compliant absolute encoders with housings made of aluminium or stainless steel for hygienically sensitive applications. The housings are encapsulated in a pressure-resistant way and can be used under the harshest conditions of temperature class T6 in Zone 1 (gases) or 21 (dusts). The enormous selection of interfaces will include the right shaft encoder for every need.
