WND100 Mast Head Unit & 20M CableWind Transducers have a tough life, experiencing extreme weather, constant movement and the occassional seagull, so it is no surprise that they can often fail. With this in mind, the WND100 wind sensor features an ultra tough design with UV and salt resistant plastics, Igildur bearings for exceptional life and corrosion resistance. Data transmission is via a super-thin 20m digital cable providing fast update NMEA0183 data for maximum compatibility with legacy instrument systems and multi-function displays.Features:Ultra tough Mast Head UnitIgildurbearings for exceptional life and corrosion resistanceUV, Salt water and high impact resistant plastics12/24v DC operation with minimal power consumptionSuper thin 20m Mast Head cableIndustry standard NMEA0183 Output for maximum compatibilityOutput at 5Hz (configurable)
