Adapter shaft easily adjusted
Options: Certified safety component to DIN EN ISO 13849-2 (PL e) and isolated version

The rugged solution for shafts without centering thread

Flange adapter shafts facilitate the convenient, simple and stable attachment of hollow shaft encoders to large shafts without a centering thread. Depending on the on-site situation they are attached to the front face of the application shaft with external centering or internal centering; consequently, they are ideal as retrofitting and replacement solutions. If required, they are also available as certified safety components with fault exclusion to DIN EN ISO 13849-2 (PL e) and as an isolated version to shield against shaft currents.

Technical Data

Attribute	Value
