Cable pinout

------Question for 0511100850-20-A-6-Z Please Put your question below------
Since I’ve seen it done either way, and it’s not defined on the drawing…
On this cable, does the wire on pin 1 (end A) connect to pin 1 (end B) or is it mirrored? The picture would suggest that’s the case, but pictures are representative, not definitive. By contrast, the 6-position cable I’m currently using…

…has the wire from pin 1 going to pin 6, mirroring the ends. I’m switching to an 8-position cable and I need a bit more length. The Molex website doesn’t have a datasheet for this assembly, since I think it’s a semi-custom internal to DigiKey. It would help if this was called out on your drawing here:

BTW, I’d use a 2185091084 except they’re backordered until September. :frowning:


Thank you for your question, I would be happy to assist.

Firstly, I can see why you may be confused regarding the actual pinout configuration as I do not see them on there either. I do know that since they are a value add product, we can make them either way. An email to indicating what you would like would be a good way to move forward.

Another solution, depending on how many you would need, is to build them the way you need them. These are the products needed to build them.



MFR PART # 503948055
DIGI-KEY PART # WM15204TR-ND - Tape & Reel (TR)




MFR PART # 511100860
DESCRIPTION 8 Rectangular Connectors - Housings Receptacle Black 0.079" (2.00mm)



Regardless of which way you go on this on I will see what I can do to help make this less confusing going forward.

I do hope this is helpful!

A chart on the datasheet showing both ends would solve the problem. If “we can build them either way”, then indicate that as an ordering option and show it. That could be as simple as a “W” option for double-terminated, pin 1 to pin 1, and the “Z” option for double-terminated, pin 1 to pin 7.

I know we can build the cables; I’m trying to avoid running stuff through our cable shop, because it costs 10X as much for us to do it by hand in-house as it does to have you guys do it with automated equipment.

Hi @markf ,

Thanks for your question. 0511100850-20-A-6-Z, contrary to the image representation, is mirrored. If a cable has a reversed connector, it will list that in the “Connector Type” or the “Features” attribute:

Instead of filtering within those boxes, typing “reverse” in the ‘search within’ search bar will find all reverse types - although I’m assuming you need non-reversed or mirrored.

Click here for 8 position non-reversed (mirrored) options.
Click here for 8 position reverse socket options.

See further explanation of ribbon cable wiring:
H8PP vs H6PP vs H0PP (DIP to DIP -vs- DIP to DIP reversed)

This old forum post describes the telecom industry standard nomenclature for modular cables and how it is represented in telecom industry standard drawings. Could be a good starting point for working out what to do to improve the datasheet.
