Furuno ST-02PSB Plastic Thru-Hull Speed and Temp Insert (6-Pin)

The Furuno ST-02PSB Plastic Thru-Hull Speed and Temperature Insert is a 6-pin transducer designed to integrate speed and water temperature data directly into marine navigation systems. This dual-function sensor eliminates the need for separate instruments, consolidating critical performance metrics into a single thru-hull installation. Built with a plastic housing, the ST-02PSB delivers reliable data transmission across a 9-meter cable, making it suitable for boats equipped with compatible Furuno chartplotters and multifunction displays.

The 6-pin connector architecture ensures secure electrical integration with Furuno's marine electronics ecosystem. Speed data allows operators to monitor actual hull performance under varying sea conditions, while integrated temperature sensing provides real-time water temperature readings—critical information for fishing applications, engine cooling system monitoring, and navigation safety. The 9-meter cable length accommodates standard installation on vessels of various sizes without requiring cable extensions or splicing. Plastic construction provides corrosion resistance in saltwater environments while reducing weight compared to metal alternatives.

This sensor is designed for boat owners and commercial operators who depend on accurate speed and water temperature data for navigation, performance monitoring, and fishing success. Recreational anglers benefit from precise water temperature readings to locate fish in thermal layers, while cruising sailors use speed data to optimize fuel efficiency and passage planning. The thru-hull design requires professional installation to ensure watertight integrity and proper transducer orientation for accurate readings.

Compatible with Furuno navigation systems that support 6-pin speed and temperature transducers, the ST-02PSB is a direct replacement or upgrade for existing installations. Verify connector compatibility with your specific chartplotter model before ordering. Marine electronics integration demands precision—this sensor delivers the redundancy and reliability expected from Furuno's professional-grade product line.
