Le FG4KK-2048G-90G-NG is a high-precision incremental encoder ideal for heavy machinery and steel industry automation. With 2,048 pulses per revolution, it provides reliable feedback for drive motors, rolling mills, and material handling systems, enabling precise control over critical industrial processes.
Due to the original model being hard to source, our custom replacement encoder is designed to replicate all original specifications, providing a drop-in solution for operators in metallurgical and steel plants.
