The FG4KK-1024G-90G-NG is a robust incremental encoder specifically designed for the steel and metallurgy industry. With 1,024 pulses per revolution, it provides precise feedback essential for controlling rolling mills, material handling conveyors, and automation systems. Built to withstand harsh industrial environments, it ensures reliable operation under heavy loads, vibration, and high temperatures.
As a legacy model, sourcing the original FG4KK-1024G-90G-NG is often challenging. We developed a custom replacement solution that replicates the original encoder’s specifications, including mechanical dimensions, electrical interfaces, and incremental output characteristics. This guarantees a drop-in replacement for operators needing continuity in production.

Expert’s note: This replacement encoder balances durability, precision, and availability, making it an ideal solution for operators facing limited supply of legacy models. Our custom service ensures long-term operational reliability for critical steel production systems.
To resolve delivery delays and procurement obstacles, we accept non-standard customization orders for the FG4KK-1024G-90G-NG. This service allows clients to obtain replacement encoders precisely matching their legacy models, while our typical lead time of 15 working days ensures a rapid response. By using this service, steel plants and heavy industrial operators can avoid production downtime and maintain system reliability.
