{"product_id":"actisense-a2k-ter-f-nmea-2000-female-micro-terminator","title":"Actisense A2K-TER-F NMEA 2000 Micro Terminator, Female","description":"\u003cp class=\"nvn-hero\"\u003eEvery NMEA 2000 network needs exactly two terminators, one at each end of the backbone, and this is the female end. The Actisense A2K-TER-F drops a precise 120 ohm resistor onto your bus so the data flows clean. It's gold-plated, sealed to IP67 when mated, and built to shrug off years of salt, spray, and vibration.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've ever chased a phantom fault on an NMEA 2000 network, a device dropping off, sensors flickering, engine data going quiet for no reason, there's a good chance the backbone wasn't terminated the way it should be. NMEA 2000 is a bus, and a bus needs a resistor at each physical end to stop the signal from bouncing back down the wire. Miss one and the whole network can turn flaky. This is the female terminator, one half of that pair.\u003c\/p\u003e\n\u003cp\u003eInside the housing sits a single 120 ohm resistor, held to 1% tolerance and rated 500mW. Put one at each end of the backbone and the two 120 ohm resistors sit in parallel across the data pair, giving the network the 60 ohms of total resistance it's designed around. That's the number that keeps the CAN data readable from one end of the boat to the other. Get it wrong and you'll see the kind of intermittent gremlins that eat a whole afternoon at the dock.\u003c\/p\u003e\n\u003cp\u003eTermination belongs at the two extremities of your backbone, never on a drop cable. Whichever connector is exposed at each end tells you which terminator you need. This female terminator mates to a male backbone connector. Its counterpart, the male terminator, plugs into a female port. You can't fudge the gender, so check the open ends of your backbone before you order. On a typical helm-to-transom run you'll end up needing one male and one female, one at each end.\u003c\/p\u003e\n\u003cp\u003eActisense built these to live outside. The contact is phosphor bronze with a gold plating for a low-resistance connection that won't corrode, carried in a glass-filled PA66 body. The screw cap is nickel-plated brass, there's a rubber O-ring seal, and the whole thing is PVC-housed and rated IP67 once it's mated. So it'll take a wash-down, a rail full of spray, a bilge that never quite dries out. The operating range runs from -25 C to +70 C, which covers just about any boat in any season.\u003c\/p\u003e\n\u003cp\u003eInstalling it is about as simple as marine wiring gets. Find the open connector at the end of your backbone, thread the terminator on, and hand-tighten the screw cap until the O-ring seats. No tools, no crimping, no power to cut. Building a fresh network from a starter kit? You'll want a pair, one male and one female. Extending an existing backbone and moving the end point? You'll re-use or replace the terminator at the new end. First boat wiring in a first sounder, or a full multi-display helm, it's the same part and the same steps.\u003c\/p\u003e\n\u003cp\u003eThe power pair is rated to 60VDC and 4A, well inside what a standard 12V N2K network ever puts across it, so nothing here is working hard. And because it's a passive resistor in a sealed shell, there's nothing to fail. No firmware, no LED, no settings. It does its one job and stays out of the way.\u003c\/p\u003e\n\u003cp\u003eNot sure your network is terminated right? The symptoms are telltale. Devices that appear one minute and vanish the next. A display that reads no data on a sensor you know is wired and powered. Gauges or targets that stutter. Any of that on an otherwise healthy install, and the first thing a good tech checks is the terminators, one at each end, correct resistance, seated tight. It's cheap insurance against a lot of head-scratching.\u003c\/p\u003e\n\u003cp\u003eThis terminator is part of the wider Actisense Micro connection range, so it seats straight onto Actisense A2K Micro backbone cable and connectors without adapters. The M12 mating thread and standard A-coded polarization follow the NMEA 2000 Micro standard, so it fits a standard Micro backbone end the way you'd expect. Two of these, or one of each gender, and your backbone is properly closed off at both ends.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e120 ohm resistor held to 1% tolerance and rated 500mW, setting the correct 60 ohm network resistance when paired at both backbone ends\u003c\/li\u003e\n  \u003cli\u003eFemale M12 connector that mates to the male end of your NMEA 2000 Micro backbone\u003c\/li\u003e\n  \u003cli\u003eGold-plated phosphor bronze contact for a low-resistance connection that won't corrode\u003c\/li\u003e\n  \u003cli\u003eIP67 sealed when mated, with a rubber O-ring that keeps out spray and wash-down water\u003c\/li\u003e\n  \u003cli\u003eGlass-filled PA66 carrier and PVC housing that stand up to vibration and sun\u003c\/li\u003e\n  \u003cli\u003eNickel-plated brass screw cap for a hand-tight install with no tools\u003c\/li\u003e\n  \u003cli\u003eRated 60VDC and 4A on the power pair, comfortable margin on a 12V network\u003c\/li\u003e\n  \u003cli\u003eWide operating range from -25 C to +70 C for any season\u003c\/li\u003e\n  \u003cli\u003ePassive sealed design with no firmware, LED, or settings to fail\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\u003eWhy does an NMEA 2000 network need two terminators?\u003c\/summary\u003e\n    \u003cp\u003eBecause it's a bus.
