Greetings,

 

I’m in the process of installing an MAC/Ray Allen trim actuator, and am wondering what the best way is to connect the five 26 gauge leads coming out of the actuator to the corresponding 26 gauge five wire control cable that will be routed up to the cockpit.  The company used to offer a small, round pin connector for that purpose, but not any more.  Would like to be able to disconnect the actuator rather than cut solder joints, if possible.  Any suggestions for a connector for fine wires like that appreciated.

I used a molex but i suspect a dsub would have been better

    Ditch the 26AWG 5wire extension and mate your

    MAC actuator to a 22AWG 5-wire bundle of your

    own making. Here's a suggested method that is

    much easier to fabricate and decidedly more

    robust as a finished installation:

Machined subD pins should work fine; if needed strip twice as much and

double the wire before inserting in the pin. If you want them 'orderly',

use a 9 pin housing; otherwise just use heat shrink over each mated pair.



Wish I could claim the idea..

I remember seeing this approach somewhere also, I want to say from Stein Bruch at Steinair.  He simply used good quality pins and sockets and then mated them and individually heat shrunk them as you describe.  I think he may have put a larger heat shrink sleeve over the entire bundle for an extra payer of protection and neatness.  It looked like a neat and tidy solution.  Certainly not as quick to disconnect as an actual connector, but then how often do you remove the elevator or tail of your airplane?



I am considering this approach, but may also just use a 0.062 pitch mini molex as they are fairly robust and small, but not weatherproof.  A 5 pin Weatherpack or Metripack is weatherproof, but much bulkier.

The technique is detailed on the       Aeroelectric Connection site; I think Bob has a 'comic book'       detailing it. But the technique is pretty much everywhere in the       wild now.

For those tiny wires I like to use crimp-type D-sub pins and sockets.

Stagger the joints and heat-shrink each one, then heat-shrink all five.

They don't need to be in a housing. It makes a fairly small and manageable

bulge.  I think Bob has a write-up on this technique.

Transition away from 26 gauge as soon as possible and use a 9 pin D-sub as a connector

Solder the 26g wires from the servo and then crimp 22g for the rest of the run.

    The last frame of this comic-book describes

    this technique:



  https://tinyurl.com/c5v2xvm



     . . . and yes, those 26AWG leads are of questionable

     design integrity. I've spoken with Ray-Allen folks

     at OSH about this numerous times 20+ years ago

     only to be rebuffed. So be it. It's their product.

     But anything less than 22AWG wire in the airframe

     bundles only increases fabrication labor and risk,

     it's not good practice in the GA industry.



     Raytheon-Beech DID use quite a bit of 24AWG wire

     in Model 390 airframe bundles. Assembly line folks

     hated the stuff but it DID save some weight in a very

     complex airplane (Premier). For our purposes

     any benefits secured by the use of tiny wires

     are washed out by degradation of robustness.

Weâ€™ve been using that method for a long time, and in fact made a quick video of it (full credit to Bob Nuckolls)!
