We offer a fully compatible replacement for the PAM90P28-BF6XXR-4096/8192 encoder, produced through non-standard customized manufacturing with a typical lead time of 10–15 working days. The replacement strictly follows the original encoder’s mechanical and electrical parameters on a 1:1 basis, ensuring identical shaft type, mounting flange, and Profibus communication characteristics. This solution helps customers resolve procurement challenges, maintain production continuity, and achieve consistent performance without modifying their existing systems.
This encoder is widely deployed in automated assembly lines, robotics, and material handling systems that require high-resolution absolute feedback and robust mechanical construction. Its 90 mm housing provides strong resistance to industrial vibration, mechanical shock, and temperature fluctuations. With the Profibus interface, it supports real-time monitoring and precise motion control, making it ideal for long-term industrial operation in demanding environments. The combination of durability, high resolution, and seamless integration ensures reliable performance in critical applications.
