For the ATM90-PXF11x13 model, we offer a reliable hollow shaft Profibus absolute encoder replacement solution, designed to address supply limitations and ensure uninterrupted industrial operations. Our replacement products are engineered to provide precise multiturn position feedback while fully matching the functional characteristics of the original encoder. With a production cycle of just 10 working days, customers can receive their replacement units quickly, minimizing downtime and maintaining efficiency in automation systems that require Profibus connectivity.
These replacement encoders have already been successfully applied in various regions, including South America, Southeast Asia, Russia, and Indonesia, earning positive recognition for their durability, mechanical robustness, and maintenance-free operation. The compact hollow shaft design enables easy integration into existing machinery while providing high shock and vibration resistance. For discontinued or difficult-to-source models, we offer customized non-standard solutions, allowing customers to maintain system compatibility and operational continuity without redesigning equipment.
