Actisense A-CONPACK-PNBF1 Screwless Connector Pack for PRO-NBF-1

The Actisense A-CONPACK-PNBF1 is the pluggable screwless connector pack that pairs with the PRO-NBF-1 NMEA 0183 buffer. If you've ever wired a buffer install at the dock with a screwdriver in one hand and a flashlight in your teeth, you'll get why these matter. The connectors clamp each conductor without a screw terminal, so you land your wire by hand and move on. There are no tiny screws to strip, drop overboard, or back themselves out over a season of vibration.

Quick refresher on where this pack lives. The PRO-NBF-1 takes one NMEA 0183 talker and feeds it to as many as six isolated listeners. That's exactly the job on a boat that's grown a chartplotter, an AIS, a radar, and an autopilot that all want the same GPS sentence off one source. The buffer mounts on a DIN rail behind the helm or in an electronics locker, and every input and output lands on one of these pluggable connectors. This pack is that pluggable half, ready to wire.

Here's the part crews love. Because the connectors are pluggable, you can wire the whole pack on the bench where the light's good, then plug it onto the buffer when you're ready. And when something acts up two seasons later, you pull the connector instead of unwiring the terminal. Chasing an intermittent 0183 drop? Unplug one listener, watch the data, plug it back. That's a five-second move instead of a ten-minute one, and you're not fighting a screwdriver in a tight locker to do it.

A few things we've learned landing these. Strip your conductors to about five or six millimeters. Under-strip and the wire barely catches, which tends to show up later as an intermittent drop right when you're offshore and want the plotter talking to the autopilot. Over-strip and you've got bare copper hanging out where it can short to a neighbor. On gauge, tinned 20 AWG grips noticeably better than thin 22 AWG, especially on a powerboat that pounds through a chop all day. If you're stuck with lighter wire, a small tinned ferrule helps it bite and stay put.

The pack gives you the connectors, not strain relief, so treat the connector as the connection and not the anchor. Cable-tie your bundle to the DIN rail or a nearby stud so the weight of the harness isn't hanging off the terminals. That's doubly true on a flybridge where the run is exposed and everything's getting shaken. On a metal hull, keep the buffer and its grounds isolated the way the manual lays out, because a ground loop into an 0183 line shows up as garbled sentences that'll have you chasing ghosts for an afternoon.

So who actually buys a connector pack? Usually one of three people. You're doing a fresh PRO-NBF-1 install and want a spare set on the shelf. You inherited a boat where the old connectors went brittle or simply walked off somewhere. Or you're re-terminating after a refit and would rather start with clean connectors than fight tired ones. What it isn't: it's not for the PRO-BUF-2 or any other Actisense buffer. Those use their own connector pack. Match the pack to the model on your rail and you're set.

If your install is growing past plain 0183, this pack still earns its keep. Plenty of crews run the PRO-NBF-1 alongside an Actisense NGW-1 to bridge 0183 data onto an NMEA 2000 backbone, so a tidy, serviceable set of pluggable connectors keeps that mixed network easy to work on down the road. Fewer screw terminals, fewer things to back out, and more time actually on the water instead of head-down at the helm.
