Reference sensor connectors. Source?

[Quicksilver]

I'm trying to find the part numbers and a source for both the male and female connectors for the 3.2's flywheel reference sensors.

I want to connect a temporary tap to pull the signal for some data logging and a short extension with a male and female on either end would make it easy in, easy out.

CONN-75853

Hope this will help.

So it looks like everyone is all selling the TE Connectors #282191-1 as the female connector. (Interesting that Mouser lists it as "Male" when the attached PDF clearly shows it as female.)
The drawing shows the male connector as "Counterpart" and it lists every spec except the part number.
On the TE Connectors site they only show a 2 connector ("2 position") male. Any other number of connectors only shows the female "splash proof" connector.

No one lists the other connector under "customers also purchased" either.
Weird...


(Wonder where the "Junior Timer" name came from?!)

I would love to know - it would be an interesting piece of esoterica for a geek like me. I don't know the full history, but back in the day, there were 4 major connector mfrs that I was aware of, 4 that my line of biz dealt with exclusively. We just called them A, B, C, & D (Amp, Bendix, Cannon, and Deutch). There were certainly more. Over the years, TYCO bought up a lot of the ones that were still around. TYCO became TE.
This info is just from my faulty memory.

The same thing happened in the discrete part industry - I did a memory dump, but I think IRC (resistors) was bought by vishay I think for example, and companies bought out each other and I stopped keeping track since it became an avalanche.

Junior Power Timer was (is?) an Amp product known by the acronym JPT. The industry used s-loads of acronyms, and the guys that remembered them all became local go-to guys in my work.
I suspect that the part was made (and named) for one particular application, and then other industries found they could use them for alternate applications. Maybe Gerry (86 911 Targa) knows.

The male / female part locating on the web-site is infuriating. when I was a pup, I could call an Amp rep who would only deal with me, and I would get my answer. Now, you wonder if you missed something or if they got it wrong (probably). Sorry, gotta go chase some kids off my lawn. :-)

Searching the Chief Enterprises number for the male connector gave me a link with a number of interchange numbers!
BOSCH 1 928 402 452
MERCEDES-BENZ 034 545 39 28
MERCEDES-BENZ A 034 545 39 28
RENAULT 77 03 297 048
SIEMENS 1701002788
SIEMENS 2260345453928

The Bosch number seems to check out. Nexus Electronics lists that they stock it and they are close by in Chino...

And just for fun that Bosch number pulls up Bosch 1 928 402 579 and 1 928 402 412 as the female connector. (The difference seems to be 1 928 402 412 is cheaper and has a boss on the side so it can be slip mounted on a metal tab. Wouldn't make a difference besides the slightly non stock look.)

I find connectors like this in the U-pull-it junkyards, usually from BMW's as the Porsche section is often missing.

I have made the exact adaptor you are describing!

Wayne - can you elaborate on how you're planning to buffer the signal(s)?
Thanks

No buffer. Just a tap to an ADC.

Found the design drawings on the Bosch Connectors website.
If you filter the "Product Family" by "Jetronic" they will pop right up. Explains a lot of the nomenclature such as "Code 1" and shows a bunch of other options in case you want to build something stock looking with different wire counts.

Nice :-)

I had to rebuild mine using fuel injector spades when my ref sensor wire pulled out. Lesson, do not pull on the wires.

Just to add options, I like these guys but I don't see the 3 pin male. They do have the boots��

Turns out that Chief Enterprises in Illinois is the North American distributor for Bosch Connectors. I called Nexus Electronics locally and they had the connectors in stock and would will-call them but they had a $50 minimum order so I'll just wait a few days...

$2.96 each which includes the housing, the crimp connectors, and the boot. Seems like a bargain!

Turns out that the Bosch 1 928 402 452 and 1 928 402 579 numbers are only for the connector housing even though the picture shows all the parts.
