We provide a reliable replacement solution for the ATM90-PUF11x13 hollow shaft Profibus absolute encoder, ensuring seamless integration into automation systems where the original device may be difficult to source. Our replacement encoders are designed to match key operational parameters of the ATM90 series, delivering stable performance even under demanding conditions. With a streamlined production cycle of 10 working days, we support fast delivery and help customers avoid downtime caused by supply shortages.
Our hollow shaft Profibus replacement encoders have been successfully deployed in South America, Southeast Asia, Russia, and Indonesia, where their durability and accuracy have been widely recognized. The rugged mechanical design allows for long service life, while features such as programmable resolution and maintenance-free operation offer clear advantages. For models that are discontinued or hard to procure, we can deliver custom non-standard replacements, providing flexibility and ensuring reliable operation in industrial environments with strong vibration or fluctuating climates.
