Interchangeable installation dimension and wiring definition for direct replacement.
Model Code Explanation
FGH40K - 2000G - 90G / 20P
- 1.FGH40: Heavy-duty encoder series, hollow shaft type
- 2.K: Double side lateral terminal box structure
- 3.2000G: 2000 pulses per revolution, incremental signal
- 4.90G: RS422 differential line driver output
- 5.20P: Hollow shaft bore diameter Ø20mm
Advantage
1. Reinforced Heavy Housing for Severe Heavy Industry Conditions.
Robust integrated cast aluminum housing with IP66 dustproof & waterproof grade. It withstands heavy impact and continuous vibration, ensuring stable long-term operation in steel plants, mines, ports and other tough working sites.
2. Fully Interchangeable with Original Hubner FGH40 Series, Easy Replacement.
Identical flange dimension, hollow shaft specification and electrical wiring definition. No base machining or circuit modification required during equipment renovation, greatly cutting your replacement cost and downtime.
3. RS422 Differential Signal, Strong Anti-Interference & Long Transmission
High precision 2000PPR pulse output. Differential signal provides excellent resistance to electromagnetic interference and supports long-distance signal transmission. Perfect for equipment with high-power frequency converters to achieve accurate speed and position measurement.
Structure Introduction
- 1.Standard circular mounting flange with evenly distributed fixing holes for firm installation.
- 2.Double-side metal waterproof cable glands, reliable protection and flexible wiring.
- 3.Built-in hollow shaft design, directly fitted onto drive shaft with high mechanical load capacity.
