We deliver a precision-engineered 1:1 custom solution for the PAM90H20-BF6XXR-4096/8192 Profibus encoder, developed through controlled non-standard manufacturing. The replacement strictly replicates the original hollow shaft structure, flange dimensions, installation depth, and Profibus-DP communication profile, allowing direct integration into existing automation systems. No mechanical redesign or PLC parameter adjustment is required. Standard production lead time is 10–15 working days, helping users respond quickly to urgent maintenance or supply chain disruptions.
Designed for demanding industrial environments, this multiturn absolute encoder supports programmable resolution up to 8192 steps and 4096 revolutions. It is suitable for cranes, lifting platforms, heavy-duty conveyors, and continuous-operation equipment where stable feedback is critical. The robust 90 mm housing withstands vibration, axial and radial loads, and temperature variations. Enhanced anti-interference capability and high-speed communication ensure reliable position data transmission for long-term, high-load applications.
