{"product_id":"actisense-a2k-mpt-2-nmea-2000-power-t-piece-3m","title":"Actisense A2K-MPT-2 NMEA 2000 Micro Power T-Piece, 3M Cable","description":"\u003cp class=\"nvn-hero\"\u003eThe Actisense A2K-MPT-2 is the power T-piece that gets 12V onto your NMEA 2000 backbone the right way. Two female micro connectors, a 3-meter UL-certified drop, and Actisense's own precision-made ends. If you're building or expanding a network, this is where the power goes in.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eEvery NMEA 2000 network needs power fed onto the backbone somewhere, and the Actisense A2K-MPT-2 is the piece that does exactly that. It drops into your backbone like any other tee, but instead of feeding a single sensor it feeds the whole bus. You get two female micro connectors and a 3-meter power cable that runs off to your 12V source. Simple, safe, and the way a network is meant to be powered.\u003c\/p\u003e\n\u003cp\u003eThe idea behind a power T is straightforward. Your backbone carries both data and power to every device hanging off it, and that power has to come from somewhere. The A2K-MPT-2 gives you a clean injection point. The two female micro (M12) connectors let it sit inline on the backbone with standard cable on either side, so it's genuinely plug and play. No cutting, no crimping on the network side. The Actisense-designed connectors are shaped for easy, secure mating, and because both ends are female, this power T is fully DeviceNet compatible too.\u003c\/p\u003e\n\u003cp\u003eIf you're new to NMEA 2000, here's the short version of why this matters. The network is a single backbone cable with a device tapped in at each tee, all of them sharing one power and data bus. Feed that bus from a good 12V source through a part like this, and every instrument on the boat talks to every other one over a single pair of wires. That's the whole appeal of the standard, and it starts with getting power onto the bus cleanly and safely.\u003c\/p\u003e\n\u003cp\u003eWe rig these into everything from center-console rebuilds to bigger cruisers adding a second helm. The rule of thumb is to put the power tee near the electrical middle of the backbone so voltage drop stays even out to both ends. Wire the red lead to a switched, fused 12V feed and the black to ground, and the network comes alive. The 3 meters of cable is usually plenty to reach the panel or a nearby bus bar. If it's long for your run, coil the slack and tuck it. And Actisense added improved strain relief at the cable exit, so the connection holds up to the vibration you get on an outboard boat running any kind of sea.\u003c\/p\u003e\n\u003cp\u003eBuild quality is where Actisense earns its name. They make their own connectors instead of buying generic ones, and it shows. The female contacts are phosphor bronze with gold plating for a low-resistance connection that shrugs off corrosion. The contact carrier is 30% glass-filled PA66 nylon, the screw caps are nickel-plated brass, and the whole housing is sealed to IP67 when mated. The cable itself is UL certified, which isn't just a nice-to-have. On charter, commercial, and surveyed vessels, UL-certified wiring is often exactly what the inspector wants to see.\u003c\/p\u003e\n\u003cp\u003eOn the electrical side it's rated at 4A per feed and 60VDC, which is more than enough headroom to power a typical NMEA 2000 backbone full of displays, sensors, and gateways. The cable uses 18 AWG tinned wires with a 34-strand tinned copper drain and an aluminum-mylar shield, so your data lines stay quiet even with the alternator charging hard. Operating range runs from -20 to +70 degrees C, so it's happy whether you're running the Gulf in July or a cold morning up north.\u003c\/p\u003e\n\u003cp\u003eOne thing to be clear about. This is the power injection point for your network, not a drop cable for a single device and not a terminator. You'll still want backbone cable between devices, a tee at each instrument, and a terminating resistor at each end of the run. If you're building a fresh backbone or adding enough new gear that your old power tap is getting warm, this is the part that keeps the whole system fed. Not sure what your network needs?
