A universal large hollow shaft absolute encoder supporting software-based intelligent programming of internal parameters, enabling flexible configuration and easy system integration.
The large hollow shaft mounting design eliminates the need for on-site zero adjustment, allowing fast and convenient installation.
Signal outputs can be freely selected and are compatible with multiple absolute encoder interfaces to meet diverse system requirements.
Featuring a safety lock bearing design, it effectively prevents shaft center displacement caused by excessive axial loads, ensuring long-term stable and reliable operation.
Compliant with the EU explosion protection standard EX II 2 G Ex ib IIB T4 Gb, it provides reliable safety assurance for petrochemical applications and various explosion-proof equipment.
