The FG40K-2500G-90G-NG is a mid-resolution incremental encoder widely used in steel plants, rolling mills, and metallurgical automation systems. With 2500 pulses per revolution, it balances precision, performance, and cost-effectiveness for industrial operations.
It is particularly valued for its rugged construction, allowing consistent operation in environments exposed to vibration, high temperatures, and airborne contaminants. Its performance ensures accurate motor feedback, conveyor monitoring, and drive synchronization, even in the harshest conditions.
Technically, the encoder provides stable and reliable signal output, suitable for medium-resolution speed control and positioning tasks. It is often applied to rolling lines, casting processes, and heavy-duty drives, where accurate feedback is critical for operational efficiency.
Given current supply chain limitations, obtaining the FG40K-2500G-90G-NG quickly can be difficult. To mitigate this, we provide a custom replacement solution designed to match the original specifications exactly. This allows operators to integrate the replacement seamlessly into their systems without modification.
Our replacement encoders are constructed from industrial-grade materials, tested for durability, reliability, and consistent long-term performance. This ensures that operators can maintain uninterrupted production while avoiding unexpected downtime.
