part number of 68M-50F

[Ogre2010]

I wanted to purchase the 68M-50F adaptor which is assumed to be connected to the NI 7344 via the SH68-C68-S cable.

Based on my understanding, it should have both the 50-pin and high density DSub 68pin male connectors.

Does anyone know the part number for this product?

The following is my tragic experience in case anyone is interested: 

We planned to design a motor driver for our customer who used the NI 7344 along with the SH68-C68-S cable.

At first, our customer recommended us the part number 184670-01 and we then query this number with NI technical support guy for the detailed data sheet, who gave me the following link

68M-50F Step/Servo Bulkhead Cable Adapter User Guide：
https://www.ni.com/docs/en-US/bundle/322543a/resource/322543a.pdf 

I thought it's OK and paid for it.

But after we received the  product, we found it is not the proper adaptor for motion control but for DAq.

After a discussion with the NI Technical support, they said they would gave me the product in this link:

 http://sine.ni.com/nips/cds/view/p/lang/en/nid/3972 

As the picture in the page shown, I think this time it should be the right on.

Again, I was disappointed. The one I received (with a part number 778262-01) was not the same thing as the picture shown on the link. It has a VHDCI connector instead of a HDSUB connector.

Since i found there are two part numbers in the above link, I asked NI if the other number (185630-01) is the right one?

Guess what? they replied me that those two part numbers represent the same thing...theysaid the difference between them is the package, manual, etc.

Till now, I am totally confused...

I'm sorry for the confusion that was caused by these mixed messages. But before I give you a recommendation I would kindly ask you to explain the exact use case to me. Instead of using a cable adapter, that was designed for a very specific purpose, wouldn't it be much easier to use a general purpose connector block with screw terminals? If you are about to design a PCB why don't you use a 68 pin connector that connects directly to a SH68-C68-S cable?

Hi Jochen, thank you very much for your prompt answer.

The idea in the very beginning is to get rid of the time-consuming soldering process.

As you know, SH68-C68-S cable has the HDSUB68 female connector (which is very popular and inexpensive on the market). for mating, we have to choose a male , panel mounted version, which is very rare, expensive and has only solder-pin verison. (not to mention the additional cost of PCB layout if R/A version is selected)

So considering the cost, we chose the NI adaptor in the first place, which is not very expensive and easy to use. All we need to do is to find a 50pin IDC version connector with flat-cable, which could be found everywhere.

However, in the current situation, I would like to ask you if you know any connector which could be used in our case.

In short, what we want is a panel mounted, male HDSub68 pin, 180 degree, solder version connector.

we used to consider the Tyco connector 2-5174339-5 or 5174339-5, but the lead times are more than 2 weeks, which is not acceptable in our case.

But if someone could tell me the correct part number of the NI adaptor, I may check with NI China to see if they have it in stock and could make the delivery shortly.

BTW, NI China is close a river, our company is just on the other side of this river. The distance between us should not be so large.

Ok, this makes things clearer now. If you want to go for the direct PCB connector, you could choose P/N 777601-01.

Unfortunately our naming conventions are not very clear for these adapters, so I'll try to resolve the confusion:

68M-50F is NOT the product name, but there are two products that start with this string:

1. P/N 184670-01 is a 68M-50F MIO Cable Adapter. This device is meant to connect 68-pin multifunction data acquisition devices to 50 pin DAQ equipment
2. P/N185630-01 is a 68M-50F STEP/SERVO Bulkhead Cable Adapter. The purpose of this device is to connect 68 pin motion control devices to 50 pin drives, like the obsolete nudrives series.

The pinout of these adapters are not compatible and only 185630-01 can be used with NI motion control boards. If you use this device, you can find the appropriate pinout in appendix B of the NI 7344 user manual.

I hope this helps,

Thank you very much Jochen.

With your comprehasive answer, I will contact the local technical support of NI.

After a discussion with NI China, they refused to replace the wrong product for us, which means we have to afford the money loss and keep the wrong type of adaptor.

They said both sides have mistakes, which we definitely disagreed. We paid the money after they gave us the wrong datasheet, now we lose money but they lose nothing.

I don't know if there is a chance to comlain this situation to NI headquarter. We are a German company, but this contract happened in Shanghai, is it possible to send the complaints to NI Germany or NI headquarter?

Does anyone have this experience?

BTW, as an alternative, we purchased the tyco's connector and planned to solder the cable manually.

I'm sorry to hear, that this situation was not resolved in a more accomodating way and I want to appologize for that.

I would appreciate it very much, if you could contact me directly (jochen.klier@ni.com) and I will try to find a way to sort things out for you. You can write in either German or English (I'm located in the German NI branch).
