The FG40KK-16384G-90G-NG is a high-resolution incremental encoder, offering 16,384 pulses per revolution, making it one of the most precise models used in steel industry automation and heavy machinery control. Its accuracy is vital for advanced drive systems, rolling mills, and positioning tasks where even minor deviations cannot be tolerated.
This encoder stands out for its ability to combine extreme precision with industrial ruggedness, functioning reliably in metallurgy environments characterized by dust, vibration, and heat. It plays a critical role in ensuring process quality and efficiency in steel production.
Due to supply chain challenges, sourcing this encoder quickly has become difficult for many operators. We address this issue by providing a custom replacement solution that exactly replicates the original encoder’s performance and installation design. This enables quick integration and avoids engineering complications.
Our replacement encoders are engineered with long-term stability and industrial-grade reliability, ensuring that they remain dependable even under continuous heavy use. This allows operators to maintain tight process control without interruptions.
We also support non-standard customization projects, delivering encoders adapted to unique industrial setups. Whether customers require mechanical modifications or signal adjustments, we can provide tailored solutions to fit their needs.
To ensure timely supply, we guarantee custom encoder delivery within 15 working days. This helps steel plants and heavy industry operators reduce lead times, overcome procurement obstacles, and sustain uninterrupted operations.
