FGH6K-2000G-90G-NG-J/50P Robust Heavy-Duty Encoder Replacement for Metallurgy Equipment
Le FGH6K-2000G-90G-NG-J/50P is designed for heavy-duty applications in the steel and metallurgy sector. As an incremental encoder, it provides precise control of speed and angular position, making it an essential part of high-torque machinery.
It is commonly installed in rolling mills, steel conveyors, and large drive motors. These environments place extreme demands on encoders, requiring both accurate feedback and resistance to shock, dust, and high heat.
With a resolution of 2000 pulses per revolution, the encoder offers both accuracy and stability. Its durable build and protective housing make it suitable for continuous operation under severe working conditions.
Metallurgical equipment requires long-term reliability to avoid costly downtime. This encoder is highly valued because it delivers consistent performance in environments where even minor interruptions can result in significant losses.
For customers facing limited availability of this model, we provide non-standard custom replacements. These alternatives are compatible with the original design and delivered within shorter lead times, ensuring minimal disruption to production lines.
