For discontinued or long lead-time PAM90H15-BF6XXR-4096/8192 Profibus hollow shaft encoders, we provide a precision 1:1 technical replacement engineered for seamless system continuity. The solution accurately matches original mounting dimensions, hollow shaft specifications, and Profibus-DP communication parameters. It allows direct installation without PLC reconfiguration or structural modification, helping reduce retrofit risk and overall replacement costs while ensuring stable multiturn absolute feedback.
With a controlled production cycle of 10–15 working days, this solution supports urgent maintenance needs and small-batch non-standard customization. The encoder offers programmable resolution up to 8192 steps and multiturn capability up to 4096 revolutions, meeting demanding motion control requirements. Each unit undergoes strict communication validation and load testing to guarantee reliable performance under vibration, axial and radial stress, and fluctuating industrial temperatures.
