We provide a dedicated replacement solution for the ATM90-PXG11x13 hollow shaft Profibus absolute encoder, designed to address market shortages and ensure continuous operation in automation systems. Our replacement encoders replicate the original model’s precision and mechanical robustness while supporting multiturn position tracking without the need for a battery. With a streamlined production cycle of 10 working days, customers can receive their encoders quickly, minimizing downtime and maintaining productivity in demanding industrial environments.
These replacement encoders have been successfully deployed in regions including South America, Southeast Asia, Russia, and Indonesia. They are valued for their rugged construction, long service life, and compact hollow shaft design, which allows easy integration into existing machinery. Additionally, for discontinued or difficult-to-source models, we offer customized non-standard alternatives that precisely meet the original technical specifications, ensuring seamless system compatibility and operational continuity.
