IP66 wind direction sensor FA20

maintenance-freehigh-performance

Product overview
The FA20 is a maintenance-free marine wind vane designed for harsh offshore corrosive environments (C5‑M). Corrosion-resistant bearings, all‑metal construction and IP66 protection provide continuous wind direction measurement for vessels, offshore platforms, meteorological buoys and marine monitoring systems.

Features

• Non-contact magnetic sensing with imported non-contact magnetic sensor chip for high measurement accuracy and strong electromagnetic immunity.
• Deeply optimized multi-passage labyrinths to achieve IP66 protection rating.
• All‑metal body: 6061 aluminium with hard anodized finish; hardware and exposed parts in 316 stainless steel for enhanced corrosion resistance.
• Special corrosion-resistant bearings qualified for offshore C5‑M environments.
• Fault-tolerant wiring design to prevent damage from incorrect connections.
• Multi-stage lightning and surge protection for maritime installations.
