The H-555555-FFFFFM-S001 is a rugged NMEA2000 Micro-C 4-way T-connector designed to create multiple drop points in a network backbone. It features a robust construction with a polyurethane (PU) outer mold and an IP68 waterproof rating, ensuring reliable operation when submerged in 1 meter of water for up to 24 hours. The connector's contacts are made from copper alloy with 30u" gold plating for superior conductivity and corrosion resistance, secured by nickel-plated zinc alloy nuts. Internally, it uses a UL1061 22AWG wire harness. This component is ideal for building or extending NMEA2000 networks on marine vessels for connecting sensors, displays, and other electronic devices.
