{"product_id":"raymarine-capteur-rotation-mat-sans-fil","title":"Wireless mast rotation sensor","description":"\u003cp\u003e\n    Designed specifically for sailboats equipped with rotating masts, the Raymarine T221 wireless mast rotation sensor provides essential correction for apparent wind angle data. Unlike traditional wind sensors that do not account for mast orientation, the T221 ensures that wind information displayed on Micronet displays is accurate, regardless of mast rotation. This feature is critical for performance optimization on racing sailboats or fast cruising boats with specific rigging, where wind data accuracy is paramount.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and system configuration\u003c\/h3\u003e\n\u003cp\u003e\n    The T221 integrates with Raymarine’s Micronet wireless system. It requires a Micronet display compatible with compass configuration (such as Digital, Dual Digital, or Remote models) and a Micronet wireless wind transmitter. For a complete solution, the system must also include either a T121 hull transmitter with a T909 compass or an STng heading source (such as an EV-1) paired with a Micro-Talk gateway. This integration flexibility allows the T221 to adapt to various Raymarine system architectures.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation, calibration, and maintenance\u003c\/h3\u003e\n\u003cp\u003e\n    For optimal performance, the T221 sensor should be installed at the masthead, no more than 1.5 meters above the deck, to ensure a clear radio link with the masthead wind unit. The bracket can be permanently fixed with non-magnetic rivets or screws, or temporarily with the supplied Velcro strap. Network integration is automatic. Calibration, which is vital for accuracy, involves keeping the mast aligned with the boat’s longitudinal axis and applying a deviation correction via the Micronet display. Battery and solar charge status monitoring is available via the MAST® section of the Health page on a Micronet display, with a \"Mast Low Batt\" alarm indicating a low level.\n\u003c\/p\u003e","brand":"Raymarine","offers":[{"title":"Default Title","offer_id":53723797750100,"sku":"T221","price":510.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_fe61c0f7-c4c6-4541-8233-a237622baf3d.png?v=1779383657","url":"https:\/\/skysat.fr\/en-gb\/products\/raymarine-wireless-mast-rotation-sensor","provider":"Skysat","version":"1.0","type":"link"}
