Two female ports and one male give you a clean drop off the trunk, gold-plated contacts that hold up season after season, and an IP67 seal once it's mated. It's the little part that keeps a whole network reliable.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Actisense A2K-T-MFF is a Micro T-piece, the small three-way connector that lets you tap one device into an existing NMEA 2000 backbone. It has two female connectors and one male connector, so it drops into the trunk line and gives you a spur, a port, to run a cable out to a chartplotter, a sensor, an engine gateway, whatever you're adding. If you've ever wired an NMEA 2000 network, you already know these T-pieces are the backbone of the whole thing. Literally.\u003c\/p\u003e\n\u003cp\u003eHere's how the network works. NMEA 2000 is a single trunk line, the backbone, that runs the length of the boat with a terminator on each end. You don't wire devices straight into that trunk. Instead you break the backbone at each device location with a T-piece and run a short drop cable off the T to the device. One T, one device. Need to add a second display at the helm? You add another T. The A2K-T-MFF is that building block, and it's built to Actisense's own interconnect and NMEA standards so the connection stays clean where it counts.\u003c\/p\u003e\n\u003cp\u003eThe build is where this part earns its keep. The male contact is brass with gold plating, the female contacts are phosphor bronze with gold plating, and gold on a low-current data connection like this matters more than people expect. It resists the micro-corrosion that quietly kills marine networks. The contact carrier is 30% glass-filled PA66, the housing is PVC, the screw caps are nickel-plated brass, and there's a rubber O-ring seal on every mating face. Thread it up hand-tight and you get an IP67 seal, so a wet bilge or a spray-soaked console won't find its way into the pins. It's rated for 4A at 60VDC, which is well beyond anything a signal-level drop asks of it.\u003c\/p\u003e\n\u003cp\u003eWhy spend on a name-brand T-piece for a part this small? Because on a boat, the network is only as reliable as its weakest connection, and a T-piece sits right in the middle of the trunk. One corroded pin or one connector that wasn't sealed properly and you're chasing an intermittent fault that drops your instruments at the worst possible moment. Gold-plated contacts, a real O-ring, and a housing that seals to IP67 are cheap insurance against exactly that.\u003c\/p\u003e\n\u003cp\u003eThis is standard M12 A-coded hardware with an M12 mating thread, the same Micro fit the rest of the Actisense NMEA 2000 cable range uses. So it mates cleanly with Actisense Micro cable assemblies and field-fit connectors, which is what makes it a genuinely versatile T-piece rather than a one-off. Sailboat, center console, trawler, it doesn't care. If the boat runs an NMEA 2000 network, this is the piece that grows it.\u003c\/p\u003e\n\u003cp\u003eTemperature range is wide too, rated for operation from -25C to +70C and storage down to -40C, so it holds up whether the boat lives on a trailer through a northern winter or bakes on a lift in the Florida sun. At 47 grams it adds essentially nothing to the run, and because the whole thing is molded and sealed there's nothing to service. You install it and forget it, which is exactly what you want from a connector buried behind a console.\u003c\/p\u003e\n\u003cp\u003eA few install notes from the dock. Keep the backbone cable running as straight as you can through the T so you're not putting side load on the pins. Don't crank the locking ring, hand-tight is the spec and over-tightening is how you crack a plastic housing. If you're rigging a saltwater boat, a dab of dielectric grease on the contacts before you mate them buys you years. And on a powerboat that pounds, throw a cable tie around the T and the adjacent cable so vibration can't slowly back a connection loose. None of it is hard. It's just the difference between a network you wire once and one you keep chasing.\u003c\/p\u003e\n\u003cp\u003eOne thing to be clear about, this is a data T, not a power T. It passes the network through and taps off a device, but it doesn't inject power into the bus. If you need to feed power to the backbone you want the Actisense Micro Power T instead. And if you've got a tight cluster of devices at the helm and don't want a string of individual T-pieces, the Actisense 4-Way connector gives you multiple drops from one point. For the everyday job of adding a single device to the network, though, the A2K-T-MFF is exactly the part you reach for. It's cheap, it's reliable, and you'll probably buy a handful at a time.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eTwo female and one male M12 Micro connector, the standard T-piece layout for tapping a single device off an NMEA 2000 backbone\u003c\/li\u003e\n  \u003cli\u003eGold-plated contacts (brass male, phosphor bronze female) resist the micro-corrosion that causes intermittent network faults\u003c\/li\u003e\n  \u003cli\u003eIP67 sealed when mated, with a rubber O-ring on every face, so wet bilges and spray-soaked consoles stay out of the pins\u003c\/li\u003e\n  \u003cli\u003eRated 4A at 60VDC, well beyond the signal-level demand of an NMEA 2000 drop\u003c\/li\u003e\n  \u003cli\u003e30% glass-filled PA66 contact carrier and nickel-plated brass screw caps for a connection that holds up under vibration\u003c\/li\u003e\n  \u003cli\u003eStandard M12 A-coded thread mates cleanly with Actisense Micro cable assemblies and field-fit connectors\u003c\/li\u003e\n  \u003cli\u003eWide -25C to +70C operating range handles northern winters and southern sun alike\u003c\/li\u003e\n  \u003cli\u003eJust 47 grams and fully sealed, so it adds no service burden once installed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Actisense reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the A2K-T-MFF T-piece actually do?\u003c\/summary\u003e\n    \u003cp\u003eIt taps a single device into your NMEA 2000 backbone.
