View Full Version : Mil/Spec connecotrs
Some of the import builders are starting to incorporate these military spec connectors and insulation into their wiring harnesses, the wire junction separators are trick too. very clean looking.

ugh I hate working with those. They are a pain in the rear to fab or re-pin.
I can only imagine. I've never seen them used on cars before today. Have they been around a while?

Cannon Plugs have been around for 40-50 years in the aviation industry

They are not too bad if you have the right tools. Unfortunately since they are mil spec the tools are pricy! There are special tools to remove the pins without damaging the pins or the connector. I will grant you that the pin labels are very tiny and hard to read.
The one shown in the original post is a MS circular connector like one shown on this page (http://www.surplussales.com/connectors/Circcon.html)
They are common in the aerospace industry and are very durable. They are also keyed so be careful if you are getting surplus ones. You want to get ones with matching keys.

Have experience through submarines :) they still suck lol. When you have a 100 pin amphenol (I know Amphenol is the company, but much like q-tips...) with an open wire, you start to hate them fast.

Though they are trick, I think a bulkhead WeatherPack connector is an overall easier option that can use readily available inexpensive installation and removal tooling.

I am a contract F-15 and A10 mechanic for the Air Force, We use these type cannon plugs throughout and not only are they reliable, but very pricey and so are the tools required to maintain them. You have to ask yourself..is the cost worth the look? A good quality connector and solder will hold for years in a car. But if you plan on flying at 24000 feet and doing 480 knots, well then the choice is obvious. just my 2 cents..

I absolutely agree. As far as connectors go, I enjoy working with Weatherpack / Metripack connectors.
The metripack also fits in well when incorporating a portion of a GM harness into the car.

I think it is a cool option if you had them laying around, or they grew legs and ended up on your shelf. They are diffently not for the novice as it is very easy to put the pin in the workng hole and ruin the connector trying to get it back out.
Cool idea, but not very practical for something that may not ever be disconnected after it is installed, unless of course you like showing it to people...
Personally I really like the weathertight plugs and I think they get the job done very well.
One thing I am surprised Jon U did not mention (since he is the resident ee) you have to be careful of the voltage levels you run through thes and are normally used for RS-422 or RS-423 applications so as long as your volts and amps are less than those it will work... But bleed over is an sob especially when your working at night, have been up 30 plus hours and guys are out in the field getting shot at!

what he said. I am an electrician on the A-10 for the air force, been working with them for 10 years. They aren't that bad, but when they get corroded, the look bad and the backshells break easy. I know this is from years or use and all. I could use them on my cars since I have access to the tools, but I wouldn't You can't just go on a cross country drive, have to make a repair, and have the pins or connectors or tools readily available.

durability also depends on which ones you get. they are not all sealed or fuel/oil resistant, for those proprieties add more $$$. they actually are easy to work with if you have the tool i deal with them on a daily basis also. the cost of the extra contact has dropped some but they are still pricey depending on which ones you need.
