Jackpost information for PXI adapter

[nickw1881]

This may be the wrong location, its a little more 'hard' than 'ware'. I am not able to find a drawing of NI 187949-10. 

I am making a custom breakout adapter for an SHC68-68-EPM type cable. The connector for this is TE Connectivity 2-5174339-5. This website says what I need: https://www.ni.com/en/support/documentation/supplemental/15/ni-daq-device-custom-cables--replacement...

The jackscrews listed on the site are a custom NI part: 187949-10, which is not available anywhere else.

Question 1: The 2-5174339-5 has M2.5 threads, the SHC68-68-EPM has 2-56 threads. Does the NI 187949-10 has M2.5 Male threads and 2-56 female threads? I know there are some different versions of the D68 connector out there, so I want to confirm.

Question 2: The 187949-10 says it comes in a set of 10. I take this to mean that there are a total of 10 connectors worth of jackposts, or 20 total jackpost pieces. Can anyone confirm that this assumption is correct?

Hi Nick,

Question 1: The 2-5174339-5 has M2.5 threads, the SHC68-68-EPM has 2-56 threads. Does the NI 187949-10 has M2.5 Male threads and 2-56 female threads? I know there are some different versions of the D68 connector out there, so I want to confirm.

- You are correct, each jacksocket screw has a 2-56 socket and 2.5M screw.

Question 2: The 187949-10 says it comes in a set of 10. I take this to mean that there are a total of 10 connectors worth of jackposts, or 20 total jackpost pieces. Can anyone confirm that this assumption is correct? 

- Each kit contains 4 screws and 4 washers. The 187949-10 part number is used to order ten kits, so in the end you'll have 40 screw and 40 washers.
