We supply a precision 1:1 technical replacement for the PAM90R28-BF6XXR-4096/8192 Profibus encoder, manufactured through controlled non-standard customization. The replacement duplicates the original mounting interface, shaft configuration, structural dimensions, and Profibus-DP communication profile, allowing direct installation without mechanical modification or control system adjustment. With a standard lead time of 10–15 working days, it provides a dependable alternative when facing supply shortages or urgent maintenance requirements.
This multiturn absolute encoder supports programmable resolution up to 8192 steps and 4096 revolutions, ensuring accurate and stable position feedback. It is widely suited for robotics integration, automated assembly systems, and material handling lines where real-time data transmission and motion precision are essential. The reinforced 90 mm housing withstands vibration, axial and radial loads, and temperature variation, while strong anti-interference performance ensures reliable communication in dynamic industrial environments.
