The FG4S-1000G-90G-NG encoder is an older heavy-duty incremental encoder model that has now been discontinued. For many customers in the metallurgical and steel industry, this has created procurement challenges since the original part is no longer available through standard channels. To resolve this issue, we provide a customized replacement solution designed as a 1:1 parameter match. This ensures that the replacement encoder can be seamlessly integrated into the same applications without requiring major system modifications. By focusing on precision engineering and strict quality control, our replacement encoders reproduce the original specifications and deliver the same level of reliability in demanding environments. Furthermore, with a fast production cycle of just 15 working days, we help customers minimize downtime and quickly restore their operations.
In terms of application, the FG4S-1000G-90G-NG was widely used in heavy-duty industrial systems, particularly in steel rolling mills, metallurgical machinery, and other large-scale equipment where robust and precise feedback was required. Its incremental signal output made it suitable for position and speed monitoring in harsh conditions where vibrations, dust, and high temperatures were common. Many customers relied on this encoder because of its long operational life and stable performance, but since it has been discontinued, operators now face the challenge of sourcing compatible replacements. Our solution directly addresses this issue by replicating the key features of the original design while ensuring availability through non-standard custom manufacturing.
