These low-profile units are nearly flush, minimizing drag with only 5 mm (3\/16\") extending outside of the hull. The housing features a water valve which minimizes water ingress into the boat when the retractable insert is being replaced with the blanking plug.\u003c\/p\u003e\n\u003cp class=\"TypographyStyle-sc-11lquxl gVBKsR\"\u003eAirmar's Smart\u003csup\u003e™\u003c\/sup\u003e Sensors have embedded microelectronics. The signals from the speed and temperature sensors are processed right inside the housing itself. All that is needed to receive data is a single cable into a compatible network or display. Available as an analog sensor or a digital Smart Sensor that can output in NMEA 0183 or NMEA 2000 protocol.\u003c\/p\u003e\n\u003ch3 class=\"section-title section-title-center\"\u003e\n\u003cb\u003e\u003c\/b\u003e\u003cspan class=\"section-title-main\"\u003eFeatures\u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSpeed and fast-response water-temperature sensing\u003c\/li\u003e\n\u003cli\u003eSpeed range: 2 to 45 knots (2 to 52 MPH)\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 protocol\u003c\/li\u003e\n\u003cli\u003eRetractable insert in a low-profile housing with a water valve\u003c\/li\u003e\n\u003cli\u003eAvailable in a plastic (P17) or bronze (B17) housing\u003c\/li\u003e\n\u003cli\u003eRetrofits into B617V, P617V, SS617V, P217, P314, or ST650 housing\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 certified cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"section-title section-title-center\"\u003e\n\u003cb\u003e\u003c\/b\u003e\u003cspan class=\"section-title-main\"\u003eSpecifications\u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCable-Length: 6 m (20') NMEA 2000® Cable\u003c\/li\u003e\n\u003cli\u003eCommon Use: Cruising\/Racing Sailboats, Leisure\/Yachting, Fishing\u003c\/li\u003e\n\u003cli\u003eData Rate: 1X per second\u003c\/li\u003e\n\u003cli\u003eFunctions: Speed, Temperature\u003c\/li\u003e\n\u003cli\u003eHole Size: 51 mm (2\")\u003c\/li\u003e\n\u003cli\u003eHousing: Plastic\u003c\/li\u003e\n\u003cli\u003eHull Material: Fiberglass or metal\u003c\/li\u003e\n\u003cli\u003eMounting Style: Low Profile Thru-Hull\u003c\/li\u003e\n\u003cli\u003ePower Rating: N\/A\u003c\/li\u003e\n\u003cli\u003eProtocol Output: NMEA 2000®\u003c\/li\u003e\n\u003cli\u003ePulses: 17,000 p\/nm* (4.8 Hz per knot)—*p\/nm = pulses per nautical mile\u003c\/li\u003e\n\u003cli\u003eRetractable housing: Yes\u003c\/li\u003e\n\u003cli\u003eRetrofits: Retrofits into B617V, P617V, SS617V, P217, P314 or ST650 housing\u003c\/li\u003e\n\u003cli\u003eSpeed Range: 2 to 45 knots (2 to 52 MPH)\u003c\/li\u003e\n\u003cli\u003eTemperature Accuracy: ±0.5°C (±1.8°F)\u003c\/li\u003e\n\u003cli\u003eTilted Element: No\u003c\/li\u003e\n\u003cli\u003eUsable Shaft Length: 57 mm (2.25\")\u003c\/li\u003e\n\u003cli\u003eVoltage: 9 to 16 VDC\u003c\/li\u003e\n\u003cli\u003eWater Temperature: -10° To 40°C (14° to 104°F)\u003c\/li\u003e\n\u003cli\u003eWeight: 0.7 kg (1.4 lb.)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Airmar","offers":[{"title":"Default Title","offer_id":51625875997009,"sku":"44-164-1-01","price":387.15,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4434\/4913\/files\/www.sailrace.com-st850-1.png?v=1754727966","url":"https:\/\/www.sailrace.com\/ru-caucasus\/products\/airmar-st850-smart-sensor-plastic-thru-hull-nmea2000","provider":"SailRACE","version":"1.0","type":"link"}
