[MRCA] External 24V Vehicular Connector?

[Ray Fantini]

I would go with the old style slave connector. That's what was used on everything prior to the introduction of the NATO style connector. The male plug can be an issue but the two pin to NATO adapter are plentiful and cheap. I have the old style on my mutt and use it to connect an external power supply, generator or also doing weird things like plugging in a 1 kW inverter I have for 120volts 60 cycle. The proper installation is to have the cables connected directly to the batteries. That way you can also jump start other vehicles.
The smaller three pin connector is ok for forty or fifty amps but the two pin slave or newer NATO connectors will power anything.
If you go with the two pin I have a couple spare two pin to NATO adapters and can give you one at Gilbert. Also I have seen many NATO style plugs that were designed for low current applications so that may be a plus.

Hi there. I am doing some radio-related electrical work on my military vehicle (1986 Land Rover Defender). One thing I want to do is to create an external connector for 24V to run things like radios outside the vehicle. I am trying to think of a good panel-mount connector that can be out in the elements, carry some modest current (maybe max 15A).  At first, I was thinking of using the NATO slave connector, but that is seriously overkill and I think I've ruled that out. I also came across this connector, but I'm not sure what mates with it:

I'm not sure if anyone knows about this connector and what mates with it, but It is an interesting option.  Something about it makes me think it might be for older vehicles? Maybe Korean war vintage? Not sure.

And finally, I saw this on ebay, this is an MX-7777B/GRC. And this connector look like a good idea. The other pic on ebay shows a screw on cover, which of course I would want. Does anyone know the MS (or Amphenol equivalent) of this connector? I don't need a whole MX-7777 just to harvest a connector hihi. It seems pretty easy to get mating connectors on ebay for this connector which makes it attractive.
