Actisense DIN-KIT-1 DIN Rail Mounting Kit for NDC-5, EMU-1 & NBF-3

If you run Actisense interface gear on your boat, you already know the boxes tend to end up zip-tied to a bulkhead or floating on a wiring loom behind the dash. That works until you need to service something. The DIN-KIT-1 fixes that. It's the factory mounting kit that clips an NDC-5, an EMU-1-BAS or an NBF-3-BAS onto a standard DIN rail, so the box sits flat, stays put, and comes off in seconds when you need to get at it.

Here's what you're actually getting. Two mounting clips and four screws. That's it. The clips screw onto the base of the Actisense unit, and then the whole thing snaps onto a rail. The DIN rail itself isn't included, and that's on purpose. Most helm and electronics panels already have rail run for breakers, terminal blocks and relays, so you just add your Actisense box to what's already there.

The kit fits two common rail standards. A top-hat rail, type EN 50 022, is the 35mm hat-section rail you'll see in nearly every electrical panel. A G-section rail, type EN 50 035, is the older G-profile rail some panels still use. The DIN-KIT-1 clips handle both, so you don't have to know which one your boat's builder fitted before you order. If it's a DIN rail, this kit works with it.

It's built for three specific Actisense boxes, all of which share the same Titan case. The NDC-5, the EMU-1-BAS and the NBF-3-BAS. The NDC-5 is Actisense's NMEA 0183 multiplexer, the box that lets you feed several 0183 talkers like GPS, AIS and autopilot into one combined output. The EMU-1-BAS is the Engine Monitor Unit, which reads your analog engine gauges and converts them to NMEA 2000 so engine data shows up on your MFD. The NBF-3-BAS is the NMEA 0183 buffer, used to split and isolate a single 0183 source out to multiple listeners without dropping signal. Same case, same mounting bosses, one kit covers all three.

Why bother mounting these on rail at all? Two reasons. First, serviceability. A box on a rail comes off with a flathead in the clip, so when you're chasing a data fault at 8am before a charter, you can pull the unit, check it on the bench, and clip it back without cutting a single tie. Second, tidiness. Marine electronics lockers get crowded fast. Rail-mounting your interface boxes lines them up next to your breakers and terminal strips instead of leaving them dangling in the loom where they chafe and rattle underway.

Installation is straightforward. Screw the two clips to the underside of the Actisense unit using the four supplied screws, then push the unit onto the rail until it clicks. To remove it, lever the spring clip down with a screwdriver and lift. No drilling into the box, no adhesive, no custom brackets. If you're doing a fresh install, mount your rail first on a backing board or panel, then add the Actisense units and your other DIN-mounted components in the order that keeps your wiring runs short.

A few honest notes. This is a mounting kit, not a rail, so if your panel doesn't have a DIN rail yet you'll need to buy a length of top-hat or G-section rail separately. The clips are matched to the Titan case, so they won't fit older Actisense products in different housings or the boxed gateways. And if your install spot genuinely can't take a rail, the Titan-case boxes also have direct-mount screw holes in the case flange, so you're not stuck. But for a clean, serviceable panel, rail is the way the pros do it, and this is the kit that gets you there.

It's a small, inexpensive part that makes a real difference in how a helm looks and how easy it is to work on later. If you're installing or refitting any of the three compatible Actisense boxes, add the DIN-KIT-1 to the order. Future-you, elbow-deep in the electronics locker, will be glad you did.
