We provide a tailored replacement for the PAM90P20-BF6XXR-1024/1024 encoder, developed through non-standard customized production with a lead time of 10–15 working days. The substitute is a 1:1 match of the original device in mechanical, electrical, and communication characteristics, including shaft configuration, mounting dimensions, and Profibus interface settings. This ensures seamless installation and eliminates the need for system modifications, offering a practical solution for users facing sourcing difficulties or supply delays.
This model is often used in mid-size automation systems, conveyor networks, and precision handling equipment. Despite its smaller resolution compared with higher ppr models, it still provides accurate absolute positioning and reliable Profibus communication, which is essential for process monitoring and motion control. Its compact 90 mm housing and robust construction allow it to perform reliably in environments with vibration, moderate shock, and variable temperatures, making it a versatile choice for industrial automation applications.
