Hello,



Can anyone recommend a good, small, preferably 

environmentally sealed connector to use on the 

five conductor cable of 22 AWG wires that run to 

each of the Ray Allen trim servos?  If I 

weren’t going to be flying in primer first 

I’d probably just splice the wires together for 

the entire run.  But with paint and control 

surface removal in the known future I’d like to 

make removal of the control surfaces easier with 

connectors on these cables.  They need to be low 

volume connectors to fit in the space where they’ll be.



Thanks,

BTW, when I try to email in questions to the list 

nothing comes through for me.  So posting 

directly to the AeroElectric List Forum.



    Not sure what you mean by 'email to the list'



    Using aeroelectric-list(at)matronics.com in your address

    is the only way to post to the list server and in this

    case, it seems to have worked for you.



    Why 'environmentally sealed' . . . that opens

    a huge catalog of choices few of which offer

    a good return on investment.



    Consider this:

    . . . for reducing the profile on a d-sub

    to allow threading through the lightening

    holes on an RV . . . not sure what your

    cable routing constraints are . . . perhaps

    a stock pair of D-Sub9 connectors would

    fit.



    If you're committed to the environmentally

    sealed variety heres an exemplar selection

    I think you'll find the rudimentary D-Subs

    adequate to the task.

   If you've got a really tight size restriction, then

   there are some pretty compact but still well enclosed

   connectors from Lemo

   I used these on a couple of programs at Beech . . . but

   they come in so many assembly options that nobody stocks

   many ready-to-install combinations. Both times I needed

   4 and 5 wire connectors, they were ordered in from a

   Lemo distribution facility that custom assembled to the

   desired option. Cost about $40 each half plus back

   shells and 6 week lead time.



   Nice connectors tho . . .

switchcraft en series is sealed, small and works well for trim 

cables. It takes reasonable soldering skill but not bad.


	


   Interesting find! Thank you. According to the

   data sheet



http://tinyurl.com/le3gwtp



   these are available in 20AWG crimp pins. There's

   a 95% chance that the el-cheepo (and platinum

   plated) 4-quadrant tools will install these

   pins. Unfortunately, Digikey doesn't stock the

   crimp versions yet but they will do special orders

   of 10 or more connectors. I'll put these on

   my list of "things to go buy and evaluate" and

   may add them to the AeroElectric Catalog. But

   if they're popular, Digikey will eventually

   stock them.



   Switchcraft is a staid, old-line supplier of

   electronic components . . . low risk.

I think this was Bob's idea but I could not find it on his 

website.  Use 5 sets of male-female D-Sub pins without any shell at 

all.  Cover each mated pair with heat-shrink.  If the joints have to 

be weather proof, use adhesive lined heat-shrink.  The heat shrink 

will have to be cut to separate the connections, not a big deal.
