The FG40KK-2048G-90G-NG is a medium-resolution incremental encoder, providing 2048 pulses per revolution, commonly used in steel production lines, conveyor drives, and heavy-duty machinery. It delivers dependable signal feedback for precise speed and position monitoring.
This encoder is trusted for its durability in harsh operating conditions, functioning reliably even in high temperatures, constant vibration, and dusty environments typical of steel plants. Its rugged design makes it a go-to solution for demanding industries.
To address supply challenges, we developed a custom replacement encoder that replicates the original model’s key specifications and installation dimensions. This guarantees smooth replacement and eliminates downtime caused by system adaptation.
Our replacement solutions focus on reliability and consistency, ensuring uninterrupted operation in high-demand applications. Steel and metallurgy operators can count on our products to maintain production efficiency.
In addition to standard alternatives, we offer non-standard customization services, delivering solutions tailored to unique equipment requirements. This ensures compatibility with a wide variety of industrial setups.
To help operators overcome long delivery cycles, we provide custom encoders with a 15 working day lead time, ensuring timely supply and reducing the risk of costly production interruptions.
