Fortunately this topic is one that has been researched thoroughly in the past. The table of parts, including the one you are seeking, is listed on the I-Pex.com website.
Just to clarify for future users,
The IPEX link you have provided is only for the connector and requires another supplier to do a cable assembly.
I've found the Mouser interposer board, can you clarify the function/requirement here? Is the interposer responsible for this requirement:
To support firmware recovery, a 3.3V controllable interrupt must be connected to the SR300 INT pin.
Or is it that as discussed in this ticket (Schematic for RealSense interposer? ) the interposer is only required to create a USB adaptor for inline connections.
To simply the build in my assembly I would prefer to have a simple cable like this:
Do you see any issues with this method?
Thanks again for your support,
Yes, the connector is made up of a number of separate parts, and the cable also has to be purchased separately. The focus in my response was on the specific part number that you were seeking.
A German website lists an adapter board for the SR300.
They also list a cable.
The interposer board provides the interface between the cable receptable and the main circuit board in the camera. The cable is also sometimes known as an interposer cable for this reason.
Pages 32 to 34 of the SR300 data sheet document explain the connector parts in detail.
Regarding your simplified design: other people can probably give better advice than I can on whether it will work, as I do not have hands-on experience of building with those parts.
