The ATM90-PXG12x12 replacement solution is engineered to maintain the reliability and accuracy of the original hollow shaft Profibus absolute encoder. This model supports precise multiturn feedback and programmable resolution, making it suitable for diverse industrial applications where stable position measurement is critical. With a production cycle of only 10 working days, our replacement units are delivered rapidly to minimize potential downtime and keep production lines running efficiently.
Our replacement encoders have been widely recognized by customers in South America, Southeast Asia, Russia, and Indonesia. They combine magnetic scanning technology, robust mechanical design, and maintenance-free operation to deliver long-term reliability in harsh environments. For hard-to-procure or discontinued models, customized non-standard solutions are available to ensure precise 1:1 matching with existing equipment, enabling a seamless transition without modifications to the system.
