Deutsch connector can be sourced in small quantities at reasonable prices from:

http://www.deutschconnector.com/

Deutsch connectors are used in Evinrude outboard motors manufactured by Bombardier, as well as in other outboard motor brands.

Good resource Jim, thanks for posting.

I recently ordered a connector from this vendor. The price for the connector was reasonable. The shipping cost was modest. I placed the order on-line via their website and paid with a credit card. I received the connector in a few days via First-Class U.S. mail.

Jim,
I know these are supposed to be crimped but can the contacts be soldered or is there a way to easily crimp them without their special crimping tool?

I need to connect my VHF to my GPS, both are on my Montauk console and out in the weather. Would you recommend a different connector?

When I ordered the connector I specified the solder cup contact inserts, and this relieved me of the burden of having to buy an expensive crimping tool. I like solder cup contacts because you can re-use them. I also ordered the gold contacts, since in my single connector installation the cost premium was not onerous.

I don't think that Deutsch would tell you this connector is designed for direct exposure to the weather or is completely water proof. Also, these connectors are not particularly compact. On the other hand, I can't think of any better alternative at the moment for the application you mention. If I do, I'll append a follow-up.

Having done many wiring repairs and modification mostly on airline type aircraft, may have some information to pass along concerning crimped verses soldered connections.

A properly crimped terminal is the ideal situation in the marine environment as in the air. The biggest downside to soldered terminals is the possibility of failure due to heat. Simply, the solder can soften or melt. This can result from either high current flow through the wire or being exposed to say normal engine heat. Induce more heat from short circuits, overheated engines or fire and you can understand why crimped is used on aircraft for safety reasons.

If it's on a system with low current flow you can afford to loose in a worse case situation you would probably have no problems.

In the case of these Deutsch connectors used in an instrumentation system, the contacts are rated for about 15-amperes while the current being carried is about 0.010-Ampere. This gives a safety margin of

15/0.01 = 1,500 times

so I don't anticipate that there will be any problems due to heating of the solder joint.

In order to re-melt a typical lead-tin alloy solder connection, the temperature has to be raised to about 400-degrees-F. If anything is getting that hot in wiring associated with serial data or instrumentation, you have a much bigger problem on your hands than worrying about the solder melting in a data connector.

The perfect connector for connecting GPS to VHF would be
genderless. I fabricated such a pair of beasts from four two-ping
connectors (they were a lot like a trailer flat four, but
only had one male and one female pin).

If you look at the end of one pair it would look like:

AB
YZ

Where A and Y are male, B and Z are female, A and B are in one
connector, Y and Z in the other.

A = NMEA IN -
B = NMEA IN +
Y = NMEA OUT -
Z = NMEA OUT +

Wire both up that way, tape the plugs together, and, it's
a kluge, but it works.

It will be really nice to have something like a Deutsch that
was built that way.

I didn't see "solder cup contact inserts" on thier web site. Are they called something else?

I got it wrong in my prior post. It should be:

AB
YZ

Where A and Y are male, B and Z are female, A and B are in one
connector, Y and Z in the other.

A = NMEA IN -
B = NMEA OUT -
Y = NMEA IN +
Z = NMEA OUT +

MMM, now that I think about it, you could build a genderless
connector from two 2-pin Deutsch connectors, one male, one
female on each side, because they are keyed.

If you are looking at end of the two connectors, key up,

On the female connector, left is NMEA - OUT, right is NMEA + OUT.

On the male connector, left is NMEA + IN, right is NMEA - IN.

Sorry for causing confusion. I used the wrong term to describe the pins and sockets I ordered. They're not called "solder cup" but "solid." I think they are really designed for crimping. Actually, I have right tool to crimp those contacts, but I prefer to solder to them. You can easily solder these contacts to the connecting wire. See this page for details:

Thanks for the info. I've ordered up a set.
