The FG4S-150G-90G-NG is an older encoder model that has been discontinued and is now difficult to source. For operators facing this challenge, we provide non-standard replacement solutions designed with 1:1 parameter customization. This ensures the replacement encoder is a direct fit and can be integrated into existing systems without the need for costly modifications. With a production cycle of only 15 working days, our solutions help customers address urgent procurement difficulties while ensuring equipment remains in reliable operation.
In its time, the FG4S-150G-90G-NG was used widely in heavy-duty applications within the steel and metallurgical industry. It was engineered to deliver precise incremental signals, enabling accurate speed and position feedback in demanding environments. Machinery such as rolling mills and industrial drives relied heavily on this encoder for smooth and reliable performance. Although no longer manufactured, our replacement solutions extend the operational life of such equipment by providing dependable and accurate alternatives.
