Identify Electrical Connectors

Hi Adam
You might have to identify the connector. Are there any markings on it or numbers. There are lots of different pins of this type and a lot of different retaining systems. It would mean searching through possibly hundreds of pictures and drawings to find one that “looks like” yours. Easier if you have one in your hand, a bit hard off a couple of pics.

What happened that you need a “couple” of contacts. If you can find them you might have to purchase up to 100. Then there comes the tooling to crimp them on the wires.

Can you purchase the harness or is it part of the car.

One avenue might be a company that specialises in car audio etc. Strathfield Car Radio is one that comes to mind but there are undoubtedly others. When it comes to tooling it might be more economical to get such a company to fix it for you.

Hi Adam, welcome to the forums!

To second what Bob has said, if you could provide us with anymore information about the model of car, infotainment screen or quadlock unit we may be able to get further as the sizing you have listed probably wont be enough to narrow it down.

Having said that, based on your pictures it seems like this is one lead of many in a harness. because of this I did some digging and think that this https://connector.pinoutguide.com/40__16_12_12__pin_Head_Unit_Car_Stereo_Quadlock/
may be a close match?

If you can provide some more information I’m sure we could get further.

Thanks

Thanks Samuel… The car is a 2014 BMW 428, and yes…the pics in the link you provided are pretty much exact. They’re the pins in blocks C and D!

Hi Adam

“pretty much” doesn’t help when you find they are “not quite” and won’t fit.

Are you showing 2 different connectors? one seems to have a metal shell and the other doesn’t. Is there any polarising mechanism to prevent reverse insertion. It is a bit hard to tell but I can’t see any.

Unfortunately that linked site does not give connector details. concentrates on pin outs mainly.

I am assuming you only want the pins (actually female sockets, if you start asking for pins you will get the male side). I think you (or someone who knows) are going to establish the connector manufacturer and type to get the matching “pins”.

You haven’t answered my previous question.

There seem to be 2 of this type of connector. Are there any unused positions on the other one with spare contacts in it that you can remove. Not very likely but you never know.

If that is a propriety connector you could have a real problem. It is likely though that a more common contact type has been used. But without manufacturers information there are a LOT of pictures and data sheets to search. Element 14 could be a good start as there are usually several filters to cut down any search but they do mostly provide data sheets which probably have drawings of the contact.
Search Contact, Female, Crimp etc NOT Pin.

Still think your best bet would be car audio specialist or auto electrician.

Hello!
I’m looking for help in identifying this connector. The female “hole” is 2,54 mm wide from each others…I think. I need to buy a couple replacements.




Hi Tama.
I have had a bit of a look but no joy so far.

“I think”, not good enough. It is 2.54 or it isn’t.

There are some connectors out there that are 2.50mm. It is a bit hard unless you are using a good micrometer to tell the difference sometimes. They are sometimes considered “sort of” interchangeable to a degree up to about 3 pins but the difference is noticeable and unusable at 6 pins. To reduce any measurement error measure from the edge of pin 1 to the SAME edge of pin 6 (so you are not estimating the centre) and divide by 5. This will spread any slight measurement error over 6 pins and thus should be very small and close enough that you could say with certainty that it was 2.54mm or 2.50mm

I would nearly bet on 2.54 but you need to make sure.
Cheers Bob

Hi Tama, Welcome to the forums!

Would you have any information about what these connects are used in? If you know what device they come from / plug into it might be possible to track it down based on that information.

Thanks!
Sam

We use this connectors in the Siemens servo motors, connected the “resolver” (encoder) to the cable.

You might find out something here.

Hi Tama
It has been 5 days now and we are no closer to finding out if your connectors are 2.50mm or 2.54mm pitch.

There are no magicians here waving magic wands. You are the one who has possession so you are the only one th provide this info.
Cheers Bob

Hey Bob
I can’t really tell, the difference is so small…
I also checked with a caliper, I measured around 2.51-2.52
Can it be 2.2 mm from hole center to hole center?

And sorry for the late response

Hi Tama
Have you done this

It is not rocket science and if you can measure between 2 pins you should have no trouble measuring across 6.
DO NOT try to estimate pin centres as the possibility for errors is greater. The difference between 2.5 and 2.54 is too small to be guessing the pin centres.
Cheers Bob

Hello Robert
You right not a rocket science, i did forget to measure. But measured now and the result 2,53mm

Regards Tamas

Unfortunately, I couldn’t find any information about the connector here either

Hi Tama
OK then we can be pretty sure it is 2.54mm
Unfortunately this does not get any closer to positively identify this connector but it does confirm one characteristic definitely.

I think this could be difficult. Are there any agents for this Siemens device reasonably locally without going to Germany.
Cheers Bob

Wanted to know the name of connector round with 8 pin i have picture and want to know to submit picture of connector
Thanks
