Hello Guys,

on my new UL, i will have 13 pins on each wing connector (3 servos, electric gear and electric brakes). all 24-22AWG wiring.

which conenctor would you recommend that would hopefully take all 13 in one case?
was thinking about a 2 row Type D15, but don know of any way to retain these when they are connected together.

Any other ideas?
thanks.

Why not just use 2 of the latching polarized Molex/Ashlock style connectors. A 1x9 pin for the 3 servos and 1x4 pin for the gear/brakes. Here is a link to what I'm talking about - http://www.hansenhobbies.com/product...nlpconnectors/

Emoctec have some rather beautiful ones at 6 servos per wing but be prepared they are $$$



PWC6 PowerWingConnector for 6 servos


Easy to handle plug system for wing wiring and up to 6 servos.
The PWC6 wing plug must be screwed between wing and fuselage. On the pin strip inside the wing the servo cables can easily be plugged and secured with the enclosed shrinking hose.
The PWC6 fuselage cable is placed inside the fuselage. On the pin strip at the end of the cable the PWC patch cables (item no. A85225) to the receiver can be connected. Also this plug connection can be secured with the enclosed shrinking hose.
The PWC PowerWingConnector system's advantages:

• Reverse polarity protection
• Vibration safe connection because of locking
• Easy mounting due to packaging
• No soldering necessary
• Up to 22A permanent current

Delivery includes PWC6 wing plug, PWC6 fuselage cable and 2 shrinking hoses.

What about our professional grade USC:

http://www.ultimate-jets.net/collect...ervo-connector




The casing is made of carbon fiber reinforced PEEK. Rated for continuous use at 250 c, MIL-STD-202. Large gold plated pins, rated at 15A peak. AWG24 to 20.
We have been using this in all our UAV for years now. It is rock solid and has demonstrated complete reliability in the worst operational conditions.
Very good feature to price ratio as well.

Here is a harness finished with our aero adhesive heat shrink and MIL spec high temperature wrap around sleeve.

http://www.digikey.com/catalog/en/pa...011&vendor=900 These are the Molex parts the Ashlock connectors use. Makeup exactly what you need and they do have panel mount housings available.

Hi

Just for info, if you incorporate electric gear and brakes in a single socket system, I would strongly advise you not to go with the flimsy Molex connectors. They are designed for PC/ IT connections.
They are rated a 1 amp and you will get heat soaking problems with all these servos/ gear connected at the same time on a fast jet in hot desert environment.

The solution I showed above is the one you need. We are running vehicles in the Middle-East on this configuration and the Molex connectors are simply not good enough in desert conditions.
Coupled to multiple high amp connections and you might head up to problems with Molex. Also note that you will need to run AWG 20 or AWG 22 cables, preferably silicon HD wires. These don't fit in the Molex setup.

Finally, our solution is sourced directly from Japan and is MIL spec rated. It is rated at twice the temperature of the regular Tyco product and not available on any online electronics distributor. Additionally the AMP range of product is limited to 50 connect-disconnect cycles. The pins we use are aero spec, rated to 5000 cycles and can withstand vibration levels of 50 Gs. We have been selling the USC for 3 years now and have not received a single complain about it.

The only cons with this solution is that you need to crimp your cables and there is a learning curve. But once you master this technique, it is so much better and cleaner than welding...

Hi Oli, could you add a picture or two about the pins?
Thanks

thats good, can you help me locate PN/S for panel mount 13+ pins Jack and matching Plug?

Olnico posted some data on the amp ratings of various connectors, the Ultimate connector may be better for what you are doing. Quick search of Digikey did not show any panel mount housings in the size you are looking for.

olnico

Here is the old graphic showing the decrease of current vs number of connectors for the Molex system.
They have increased the performance of the pins and I believe that max current with AWG20 is now 3 amps vs 2 for the older pins. But it gives a good idea of what happens when increasing the number of connectors.

Using these in our spacecraft. Uber reliable.

Hi
Try these with 16 pins. This is the male plug, but in related products you will find female and 20AWG pins to crimp. Choose the golden ones

http://www.digikey.pt/product-detail...9536-ND/664288

Seem the same as Ultimatejets. I have these in my Mibo A10 for arround 20 flights now with no problems. Will change all other jets for these. Bye bye MPXs and others..... :-)

Best regards

Thanks Nuno.
i can find 4 sets of pins (all golden) under that page, but all female sockets are not golden? or do you have appripriate digikey P/Ns?
also what kind od crimp tool is required for these?

thanks again.

olnico

Almost.
Our housings are sourced directly from Japan and made of carbon fiber reinforced PEEK. They sustain 250c continuous.
Here is a comparative test between our MIL spec wrap around sleeve and the USC housing exposed to a 600c heat flow.

https://vimeo.com/92129548 The connectors we offer are the mIl spec versions. They have a thicker gold plating surface and we certify it to our military customers to MIL-STD-202 and 5000 connect/ disconnect cycles.

or

For MIL certified crimps.

However our ratchet crimping tool does a decent job for hobby purposes.

I can vouch for Oli's 20-pin connectors, just installed it on my new Tomahawk F-5, great quality, used also his 20AWG servo wire.

Thanks Oli once more for your contribution to the hobby.

It's always a pleasure to help you, Tassos.
By the way, beautiful installation!
Pass by the shop, I'll give you a short section of wrap-around sleeve and some clips to protect that big bundle of wires. It will look even better...

Tried to order them from Digikey but its only showing pins in 3500pc reel.
any idea how do i order smaller amounts?

That's just not fair Oli. I have known you for a hundred years and you never invite me to "The Shop"

Man, any time!
Check my roster and call me.
I'd love to have had you there earlier but we're both so busy! Just consider that it took Tassos two months of hard work to get to find a slot to see me!!!
